I have built the very latest u-boot release and placed the image on a Raspberry PI. After boot, I get this error message:
U-Boot 2013.10 (Oct 24 2013 - 09:35:44)
DRAM: 448 MiB
WARNING: Caches not enabled

mmc0 is current device

Obviously, u-boot failed to mount the file system.
Can this be related to some mmc related setting as access speed?
Thanks in advance

On one of my raspberry pis (Raspbian OS) with a USB serial device connected, there is periodic disconnection of the serial device while still being registered as a USB device.
lsusb returns a valid Bus Device entry, but there is no corresponding /dev/serial/ entry.
The only way to fix this issue is rebooting the pi, which I'd like to avoid.
I'd love some ideas on how I can debug USB serial connections on a Raspberry Pi Linux platform, or methods to reset the serial connection without requiring a reboot.
We tried:
Tracking udevadm monitor to see USB related events. This is what is seen where we catch a serial disconnection / reconnection happening:

Checking if the raspberry pi was overheating, using vcgencmd. It returns 8000 Soft temperature limit has occurred flag sometimes, but not always.
Tried the following method to "reset" the serial connection, which had no effect
echo -n '1-1.3:1.0' | sudo tee -a unbind
echo -n '1-1.3:1.0' | sudo tee -a bind
Followed some of the solutions here: https://raspberrypi.stackexchange.com/questions/9264/how-do-i-reset-a-usb-device-using-a-script, including the solution to reset the USB bus, with no luck.
USB Serial malfunctioning may be caused by many different factors, including software, hardware or noisy environment.
The following diagram roughly describes the related components,

| Userspace (Apps) | | Power Supply |

| Kernel (Drivers) | <-- | USB Cable | <-- | Device |
-------------------- ------------- ----------
Narrow down to the faulty part
As first step, elimination method can help us to narrow down to the faulty part, basically you replace the suspect part with another good component, and observe if it changes result. for example,
use the latest official raspbian image to eliminate userspace issue
choose a different kernel/firmware image to eliminate kernel/driver issue
change usb cable
change usb device
use a decent power supply
Troubleshooting on software issue
Assume we could narrow down the scope to software, I would use the following procedures to do further check,
Make sure the usb device is recognized by kernel, check with lsusb, dmsg, udevadm.
Have a correct name (dev path), check udev rules;
Run udevadm monitor to observe any unexpected disconnection events, make sure it works (stable connection) on a fresh OS image, and install only necessary packages step by step.
Other tips
Check if your usb device is a "smart" device? meaning the device may have its own logic to disconnect or change mode, so that affect your host side connection.
To see what happened on the USB bus it is better to use usbmon (see https://wiki.wireshark.org/CaptureSetup/USB).
I think you should carefully check usb descriptors: lsusb -v and check how much current it attempts to take (check configuration descriptor: https://learn.microsoft.com/en-us/windows-hardware/drivers/usbcon/usb-configuration-descriptors).
I think reconnects could occur due to insufficient current to you usb device especially if device supplied only from bus. If current > than usb host controller can provide, usb host-controller limits current this could lead to device reset. To check this hypothesis connect your device to Raspberry using active hub with external power supply.
I wanted to get my feet wet with AOSP on my MacOS M1 (ARM64) with Big Sur, but it looks like there is no configuration build for this host.
When I look under build/soong/cc/config I only see one Darwin related file, namely x86_darwin_host.go.
With the latest aosp release, namely android-11.0.0_r35 I'm able to build a generic arm64 target, but the resulting emulator does not boot. Configuration shows that the HOST is detected as x86_64, in fact binaries generated are in x86_64 format.

Any idea how I can debug what is wrong with the initrd image?

Good luck, let us know if it works to you!
I have a Segger J-Link which I am trying to use on a Macbook running MacOS Catalina 10.15.4, with openocd and GDB against an ESP32 board. The problem is that I can not seen the device:
$ ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port /dev/cu.JimsiPhone-WirelessiAP /dev/cu.SLAB_USBtoUART /dev/cu.usbserial-0001
None of these is the J-Link. If I run lsusb I can see it:
$ lsusb
Bus 020 Device 002: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 020 Device 003: ID 1366:0101 SEGGER J-Link ARM
I have installed the "J-Link Software and Documentation Pack" downloaded from Segger. I have checked the Mac "Security and privacy" settings and it does not report that it blocked any drivers or programs from being installed or run.
On the J-Link, the green LED is on, with a very brief flash about twice per second.
I'm sure I have a piece missing, and would appreciate some help.
UPDATE: I have been following instructions here:
OpenOCD Instructions
It all works until I get to step 6, and I follow these instructions:
Serial driver instructions
The problem is, a path for the driver never shows up, as I described above. I don't think I can run OpenOCD if I can't make it talk to my J-link.
When I run openocd-esp32, I get (full paste from openocd-esp32 output is below):
Error: No J-Link device found.
The contents of esp32-wroom-32.cfg is:

After doing the above I now get a different error message when running openocd-esp32 (perhaps because of the J-Link FW upgrade?). Initially it complained that there was not an adapter speed set, so I modified interface/jlink.cfg and added:
adapter_khz 3000
I now get a different error:
Error: JTAG scan chain interrogation failed: all ones
Which I have been Googling, and which could mean a bad board or still another configuration issue. There is no SD card in the SD card socket and no other SPI devices on the board, although the ESP32-WROVER-32U has SPI flash on it.
Here is the complete output from openocd-esp32:

I would suggest to validate your setup step by step - I personally do not like big bang integrations.
Verify that your the Segger software can see your JLink probe - the good thing is that lsusb can see it. JLink Commander should provide some useful information.
Launch openocd without any executable-related arguments: openocd -f interface/jlink.cfg -f board/esp-wroom-32.cfg
Verify that basic commands are working, i.e. resetting the CPU, displaying registers, reading/writing memory.
If you you are still experimenting issues, double-check your wiring - see here for more information.
I have an old Solaris SPARC application that I'm trying to get running.
I learned from this question that x86 Solaris won't cut it. I recently learned that VM virtualbox can't emulate SPARC architecture. Therefore, I am currently trying to emulate Solaris 10 SPARC using QEMU.
I have acquired a Solaris 10 SPARC iso (sol-10-u11-ga-sparc-dvd.iso) from here.
I have Qemu 3.1.50 installed.
However, when I try to run, it gives me:

What am I doing wrong here?
You're trying to run with only 512 mb of RAM:
...qemu-system-sparc64" -m 512 ...
Per the Oracle Solaris 10 1/13 Installation Guide: Planning for Installation and Upgrade page on System Requirements and Recommendations:
For UFS or ZFS root file systems, 1.5 GB is the minimum memory required for installation. However, note that some optional installation features are enabled only when sufficient memory is present. For example, if your system has insufficient memory and you install from a DVD, you install through the Oracle Solaris installation program's text installer, not through the GUI.
The current version of QEMU (I last tested with 4.1) does not support SPARC64 systems well yet. While the instruction set is supported, to run OpenSolaris the rest of the hardware needs to be emulated too. The system emulation code is not finished yet, but I have seen some slow progress on Git.
I have a f1-micro instance running on Google Compute Engine running CentOS.
Some time ago I got a mail stating that the zone I am using (us-central1-b) is going through a hardware upgrade to new Hashwell servers, and all instances need to be restarted. So, I did restart. I shut down my services, and performed a restart via the developer dev. console.
But the instance never came up - the boot on the new hardware failed, and now I can not log in to the instance with ssh. I will add the serial console content below this.
My main issue is that there are some content I would really like to get my hands on (nope - didn't do a full backup - shoot!).
How do I restore the instance, when I can not log in using ssh?
Changing serial settings was 0/0 now 3/0

I suggest at first to follow standard troubleshooting steps to validate the disk's filesystem as documented.
Then you can try to snapshot the disk and create a new instance with boot disk from snapshot to avoid exclude a disk UUID conflict.
Finally you can try to attach the disk to recover the files to a brand new instance as I suggested in my previous comment.
If you can not validate the filesystem as per troubleshooting guide the data is most probably lost and nothing more can be done to recover it.
Please note as a good practice to take care of either periodic snapshot, GCS differentiual backup or other replication method.
Thank you.
Sincerely,
P.
