Procedure inquiry when using RPMB - raspberry-pi
I am studying RPMB in Raspberry pi 3B model.
The development environment I have configured is as follows. For reference I tested two eMMC modules.
Target : Raspberry pi 3B Storage
Storage
eMMC module made by hardkernel
eMMC: https://www.hardkernel.com/shop/8gb-emmc-module-xu4-linux/
eMMC Reader: https://www.hardkernel.com/shop/emmc-module-reader-board-for-os-upgrade/
eMMC module made by uugear
https://www.uugear.com/product/raspikey-plug-and-play-emmc-module-for-raspberry-pi/
firmware: 2021-05-07-raspios-buster-armhf-lite.zip
After the above configuration, the following work was carried out.
In ubuntu pc
1. Initialize the partition using fdisk
2. Write firmware image to eMMC.
- unzip -p 2021-05-07-raspios-buster-armhf-lite.zip | sudo dd of=/dev/sdd bs=4M conv=fsync
After raspbian is written successfully, the partition configuration checked through fdisk is as follows.
Command (m for help): p
Disk /dev/sdd: 7.3 GiB, 7818182656 bytes, 15269888 sectors
Units: sectors of 1 * 512 = 512 bytes

/dev/sdd2 532480 15269887 14737408 7G 83 Linux
After that, I inserted the eMMC module into the sdcard in raspberry pi3 slot and booted it up successfully.
Looking at the log during booting, 512KB of mmcblk0rpmb chardev was recognized as shown below.

After I booted, when I checked the device, it was not found in lsblk, but when I searched the /dev directory, rpmb dev was also found.

I installed mmc-utils for RPMB test, and first checked extcsd information.

I know that RPMB runs in the trustzone zone. I am analyzing optee.
As a result of checking the RPMB-related code in optee, I understand that reading the write counter value should be performed even if the HMAC key is not injected into the eMMC.
(HMAC Key is One Time Programmable, so I am approaching it with caution.)
For reference, the kernel version currently used in raspbian is as follows.
pi#raspberrypi:~ $ uname -a
Linux raspberrypi 5.10.63-v7+ #1457 SMP Tue Sep 28 11:25:31 BST 2021 armv7l GNU/Linux
I have not made any modifications or additions other than the above work. All of the eMMC modules I purchased (hardkernel, uugear) are experiencing the same problem.
If anyone knows how to solve this problem, please help me.
That is most likely because the area has not been used - the key has not been written.
Try reading the counter after setting the key with 'mmc rpmb write-key' command ( and yes, this is one-time operation).

Respberry Pi 4 debian HDD not detected on USB3 but works on USB2
I have a brand new Raspberri Pi 4 loaded with NextCloudPi_11-27-20 image on the SD which seems to boot and work perfectly. The system info tells me that the distribution is: Debian GNU/Linux10 \n\l I am a linux noob, but think debian is causing the following problem. I have a 4tb HDD in an USB3.0 enclosure (DELOCK 42613) which should support UASP If I connect the HDD to USB3 it does not show up on sudo fdisk -l If I connect to USB2 it works fine. Where can I start to investigate this problem? How can I get it to work on the USB3.0 port? edit 2020-12-14 17:05: sudo dmesg output (part of it, characters limit 30000): pi#nextcloudpi:~ $ sudo dmesg [ 1423.007653] usb 2-2: SerialNumber: 0123456789ABCDEF [ 1423.020119] scsi host0: uas [ 1423.026589] scsi 0:0:0:0: Direct-Access JMicron Generic 0508 PQ : 0 ANSI: 6 [ 1423.027759] sd 0:0:0:0: Attached scsi generic sg0 type 0 [ 1423.029003] sd 0:0:0:0: [sda] 7814035055 512-byte logical blocks: (4.00 TB/3. 64 TiB) [ 1423.029017] sd 0:0:0:0: [sda] 4096-byte physical blocks [ 1423.029705] sd 0:0:0:0: [sda] Write Protect is off [ 1423.029720] sd 0:0:0:0: [sda] Mode Sense: 53 00 00 08 [ 1423.030162] sd 0:0:0:0: [sda] Disabling FUA [ 1423.030175] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, does n't support DPO or FUA [ 1423.031003] sd 0:0:0:0: [sda] Optimal transfer size 33553920 bytes not a mult iple of physical block size (4096 bytes) [ 1423.060421] sda: sda1 [ 1423.063607] sd 0:0:0:0: [sda] Attached SCSI disk [ 1423.243629] BTRFS info (device sda1): disk space caching is enabled [ 1423.243638] BTRFS info (device sda1): has skinny extents [ 1429.361794] usb 2-2: USB disconnect, device number 6 [ 1429.364055] sd 0:0:0:0: [sda] Synchronizing SCSI cache [ 1429.410539] btrfs_dev_stat_print_on_error: 17 callbacks suppressed [ 1429.410558] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 1, flush 0, corrupt 0, gen 0 [ 1429.410641] BTRFS error (device sda1): error reading free space cache [ 1429.410661] BTRFS warning (device sda1): failed to load free space cache for block group 30408704, rebuilding it now [ 1429.413058] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 2, flush 0, corrupt 0, gen 0 [ 1429.413142] BTRFS error (device sda1): error reading free space cache [ 1429.413161] BTRFS warning (device sda1): failed to load free space cache for block group 1104150528, rebuilding it now [ 1429.413300] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 3, flush 0, corrupt 0, gen 0 [ 1429.413389] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 4, flush 0, corrupt 0, gen 0 [ 1429.413528] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 5, flush 0, corrupt 0, gen 0 [ 1429.414158] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 6, flush 0, corrupt 0, gen 0 [ 1429.417529] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 7, flush 0, corrupt 0, gen 0 [ 1429.419569] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 8, flush 0, corrupt 0, gen 0 [ 1429.419721] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 9, flush 0, corrupt 0, gen 0 [ 1429.422261] BTRFS error (device sda1): bdev /dev/sda1 errs: wr 0, rd 10, flus h 0, corrupt 0, gen 0 [ 1429.434640] BTRFS: error (device sda1) in btrfs_commit_transaction:2280: errn o=-5 IO failure (Error while writing out transaction) [ 1429.434694] BTRFS info (device sda1): forced readonly [ 1429.434865] BTRFS warning (device sda1): Skipping commit of aborted transacti on.

Apparently this is a known problem: STICKY: If you have a Raspberry Pi 4 and are getting bad speeds transferring data to/from USB3.0 SSDs, read this I would not be surprised if there is a similar question on SO In short: Something to do with the chips in the SATA adapters to USB and UAS. (if I got it right) Please go to the link above for the full story. Quick solution: Get the idVendor=xxxx and idProduct=xxxx by disconnecting the adapter, run sudo dmesg -C, reconnect and run dmesg sudo nano /boot/cmdline.txt and add at the start of the line of parameters 'usb-storage.quirks=[idVendor]:[idProduct]:u' In my case it looks like this usb-storage.quirks=152d:0578:u from the code snippet in my question. reboot check with dmesg | grep usb-storage, you should see something like this: [ 2.495725] usb 2-1: UAS is blacklisted for this device, using usb-storage instead [ 2.512739] usb 2-1: UAS is blacklisted for this device, using usb-storage instead [ 2.531823] usb-storage 2-1:1.0: USB Mass Storage device detected [ 2.549642] usb-storage 2-1:1.0: Quirks match for vid 2109 pid 0715: 800000 [ 2.566177] scsi host0: usb-storage 2-1:1.0
Set burst for bandwidth limit for a pod
For what I know, there're two way to limit bandwidth with k8s.
First, configure the CNI with
{
"type": "bandwidth",
"capabilities": {"bandwidth": true},
"ingressRate": 10000000,
"ingressBurst": 10000000,
"egressRate": 10000000,
"egressBurst": 10000000
}
And second, annotate a pod with:
annotations:
kubernetes.io/ingress-bandwidth: 8M
kubernetes.io/egress-bandwidth: 8M
I read through the documentations but didn't find any way to configure burst for a pod.
But the default burst is too large to make the limitation useful:
qdisc tbf 1: dev calia2333445823 root refcnt 2 rate 8Mbit burst 256Mb lat 25.0ms
And it seems when the CNI is configured with bandwidth limit, then pod annotations will not override the CNI's configure and take effect.
So how can I set a burst for just a pod?
iperf output to illustrate the burst:

Environment:
Kubernetes 1.15.7
Calico v3.11.1
bandwidth plugin v0.8.0
tc iproute 4.11.0-14.el7
Unfortunately current implementation of bandwidth control does not support limiting burst for pod. I had the same results testing this. I also looked at the cni code on kubernetes github and found out that there are only annotations visible are for ingress bandwidth and egress bandwidth. bandwidthAnnotation := make(map[string]string) bandwidthAnnotation["kubernetes.io/ingress-bandwidth"] = "1M" bandwidthAnnotation["kubernetes.io/egress-bandwidth"] = "1M" Since network shaping is still in alpha stage you could raise a request on github and ask for this functionality.
mount - can't find /dev/sdc in fstab error
I'm trying to mount xfs disk. I prepared directories. sudo mkdir /grid/; sudo mkdir /grid/0; then I tried sudo mount -t xfs /dev/sdc /grid/0; But I always receive can't find /dev/sdc /grid/0 in /etc/fstab My fstab looks like this # # /etc/fstab # Created by anaconda on Tue Dec 18 11:05:19 2018 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/rhel-root / xfs defaults 0 0 UUID=xxx /boot xfs defaults 0 0 UUID=zzz /boot/efi vfat umask=0077,shortname=winnt 0 0 /dev/mapper/rhel-home /home xfs defaults 0 0 /dev/mapper/rhel-var_log /var/log xfs defaults 0 0 /dev/mapper/rhel-swap swap swap defaults 0 0 /dev/sdc /grid/0 xfs defaults,noatime 0 0 /dev/sdd /grid/1 xfs defaults,noatime 0 0 /dev/sde /grid/2 xfs defaults,noatime 0 0 /dev/sdf /grid/3 xfs defaults,noatime 0 0 /dev/sdg /grid/4 xfs defaults,noatime 0 0 /dev/sdh /grid/5 xfs defaults,noatime 0 0 /dev/sdi /grid/6 xfs defaults,noatime 0 0 /dev/sdj /grid/7 xfs defaults,noatime 0 0 is something wrong with my fstab ?

The issue was caused by non-breakable space which was mixed in fstab records and in mount command. After converting text to ASCII and checking on "Show All Characters" in notepad++ I replaced all non-breakable space with ordinary space and command finished successfully.
Matlab crashes when plotting specific 3D functions
Matlab crashes (closes) when I try to plot a 3D function of the like z=(x,y), whenever the function involves the following conditions together: incorrect multiplication and power notation: e.g. x*y^2 instead of x.*y.^2 x,y support grid very small: e.g. meshgrid(0.01:.01:0.99) For example, the following code doesn't work: [x,y] = meshgrid(0.01:.01:0.99); z=x*y^2; surf(z) Same happens if I use mesh instead of surf. Normally, you would expect an error about the notation. It seems to be a bug of Matlab.

http://www.mathworks.com/support/contact_us/ A technical support engineer might contact you with further information. Thank you for your help. In suggestion from this forum, I submitted a service request. Clearly, I solved my problem by using the correct dot notation. Yet, regardless of any wrong notation, Matlab should not crash. I will update this post once I receive further information and either delete or answer this question.
Measure height of 3d block for [x y] point
I have following data: kx = 20; ky = 20; k = [kx ky]; PointsL = [ [ 32 0 0] % P1 [387 0 0] [475 0 0] [475 30 0] [602 30 0] % P5 [602 220 0] [475 220 0] [475 737 0] [387 737 0] [ 32 737 0] % P10 [ 32 555 0] [ 0 555 0] [ 0 277 0] [ 27 277 0] [ 27 250 0] % P15 [ 0 250 0] [ 0 57 0] [ 32 57 0] % P18 ]; PointsH = [ [ 32 0 270] % P1 [387 0 270] [475 0 183] [475 30 183] [602 30 183] % P5 [602 220 183] [475 220 183] [475 737 183] [387 737 270] [ 32 737 270] % P10 [ 32 555 270] [ 0 555 270] [ 0 277 270] [ 27 277 270] [ 27 250 270] % P15 [ 0 250 270] [ 0 57 270] [ 32 57 270] % P18 ]; PointsL are points of the lower surface - all with z=0. PointsH are points of the higher surface - changable in z-axis. All of them are representing points of room. Following code draws 3d model: plength = size(PointsL,1); for i=1:plength if i == 1 pl1 = PointsL(plength,:); ph1 = PointsH(plength,:); else pl1 = PointsL(i-1,:); ph1 = PointsH(i-1,:); end pl2 = PointsL(i,:); ph2 = PointsH(i,:); line([pl1(1) pl2(1)], [pl1(2) pl2(2)], [pl1(3) pl2(3)]); line([ph1(1) ph2(1)], [ph1(2) ph2(2)], [ph1(3) ph2(3)]); line([pl1(1) ph1(1)], [pl1(2) ph1(2)], [pl1(3) ph1(3)]); end p1 = PointsH(2,:); p2 = PointsH(9,:); line([p1(1) p2(1)], [p1(2) p2(2)], [p1(3) p2(3)]); p1 = PointsH(4,:); p2 = PointsH(7,:); line([p1(1) p2(1)], [p1(2) p2(2)], [p1(3) p2(3)]); Is it possible to get height (z value) for given x,y values ?
Ok, I was going to say that this could easily be done using TriScatteredInterp() on PointsH. I realised that it was not that simple to get it to produce what I wanted. I resorted to adding extra points and moving them around to create the right interpolation triangles. I finally got something that can produce the z-value corresponding to the point (a,b). Here is what I ended up doing... epsilon = 1e-8; PointsL_diff = epsilon*[ [ -1 0 0] % P1 [ 0 -1 0] [ 0 -1 0] [ 1 0 0] [ 0 -1 0] % added [ 1 -1 0] [ 1 0 0] % P5 [ 0 -1 0] [ 1 1 0] [ 1 1 0] [ 0 1 0] [ 1 0 0] % added [ 0 1 0] [ -1 0 0] % P10 [ 0 1 0] % added [ -1 1 0] [ -1 1 0] [ -1 0 0] [ 0 -1 0] % added [ -1 -1 0] [ -1 1 0] % P15 [ -1 0 0] [ 0 1 0] % added [ -1 -1 0] [ -1 -1 0] % P18 ]; PointsL = [ [ 32 0 0] % P1 [ 32 0 0] % added [387 0 0] [475 0 0] [475 0 0] % added [475 30 0] [602 30 0] % P5 [602 30 0] % added [602 220 0] [475 220 0] [475 737 0] [475 737 0] % added [387 737 0] [ 32 737 0] % P10 [ 32 737 0] % added [ 32 555 0] [ 0 555 0] [ 0 277 0] [ 0 277 0] % added [ 27 277 0] [ 27 250 0] % P15 [ 0 250 0] [ 0 250 0] % added [ 0 57 0] [ 32 57 0] % P18 ]; PointsH = [ [ 32 0 270] % P1 [387 0 270] [475 0 183] [475 30 183] [602 30 183] % P5 [602 220 183] [475 220 183] [475+epsilon 220 183] % added [475 220+epsilon 183] % added [475 737 183] [387 737 270] [387 220 270] % added [ 32 737 270] % P10 [ 32 555 270] [ 0 555 270] [ 0 277 270] [ 27 277 270] [ 27 250 270] % P15 [ 0 250 270] [ 0 57 270] [ 32 57 270] % P18 ]; % plot bounds x_min = -200; x_max = 800; y_min = -200; y_max = 800; newPointsL = PointsL + PointsL_diff; x = [PointsH(:,1); newPointsL(:,1); x_min; x_max; x_min; x_max]; y = [PointsH(:,2); newPointsL(:,2); y_min; y_min; y_max; y_max]; z = [PointsH(:,3); newPointsL(:,3); 0; 0; 0; 0]; F = TriScatteredInterp(x,y,z); % default is linear interpolation % find z-value for point (a,b) a = 100; b = 200; z_value = F(a,b) % generate mesh and plot surface ti_x = x_min:10:x_max; ti_y = y_min:10:y_max; [qx,qy] = meshgrid(ti_x,ti_y); qz = F(qx,qy); mesh(qx,qy,qz); hold on; plot3(x,y,z,'o'); ... and here is the figure the code produces:
