I want to trace exceptions/interrupts happening in my board with STM32L4xx in Atollic Studio by SWV Exception Trace Log and SWV Trace Log.
I use SEGGER J-Link and In Debugger I have correctly set the interface to SWD and the Core Clock to 80 MHz. Also in the Serial Wire Viewer setting, I set the EXETRC and Enable Prescaler. By pressing Start Trace, I get the following verification error in console:

Do you know what could be possible problems?

Has anyone had a similar problem?
This link says it means there is something wrong with the esp file system rendering it "broken"... Not sure if there is a way to fix the issue though.
EDIT:
I found that if I disconnected some of my peripherals from esp32, the error went away. Perhaps too much power was being drawn.
The code is working. I can build it and to mention. it was working, i could upload it to my custom made ESP32 board. From all of a sudden it stopped working. Tried with different PCB boards also different cables.
I somehow resolved my problem so i can program it, but now i get a verification error after Programming Finished
Here is my complete log from terminal.

I'm using the Raspberry Pi 4 and trying to have an Internet access using the A9G GSM/GPRS+GPS Module.
At first I have install ppp with sudo apt-get install ppp screen elinks
I have create a file with name rnet in path /etc/ppp/peers/rnet:
# My APN internet.vodafone.gr
connect "/usr/sbin/chat -v -f /etc/chatscripts/gprs -T internet.vodafone.gr"
# Communication port:

# Do not ask the remote to authenticate.

In file gprs in path /etc/chatscripts/gprs I have add the line that need my "MY_4_DIGIT_PIN":
ABORT BUSY
ABORT VOICE
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "NO DIAL TONE"

# except for 1 which means "full functionality".
#OK AT+CFUN=1

So when I'am trying to starts up the rnet file:
sudo pon rnet
I get this error message in syslog (cat /var/log/syslog | grep pppd):
Oct 14 18:14:22 raspberrypi pppd[3063]: pppd 2.4.7 started by pi, uid 0

...
When I am trying to run the below AT commands, the module seems to be work fine and be able to connected to network:
AT

AT+CPIN?
+CPIN:READY

So I can't understand if I have have writing something wrong in file rnet or is something else that I am not doing it right. If you have any idea please help me.
The problem was that my A9G Module, was not getting enough power.
Therefore, check if your A9G Module is turned on, before starting the process
and make sure that you have disabled login shell to be accessible over serial,
and also you have enabled the serial interface.
I need to port ecos on new platform board with u-boot.
Everywhere I am able to find Porting guide for ecos with redboot.
Did anyone booted ecos with u-boot?
I got some link which tells it's possible to boot ecos with u-boot?
https://sourceware.org/ml/ecos-discuss/2010-06/msg00038.html
But I am not able to find any document regarding that.
I tried following following procedure to boot ecos with u-boot
compiled ecos 3.0
ecosconfig new
ecosconfig tree
make
cross compiled and generated sample hello_world elf linking library
generated in previous make.
Powered on the board and stopped at u-boot(prebuilt u-boot already in
flash)
Transferred hello_world to a load_addr(entry point address of RAM) through tftp
bootelf load_addr
But it got hanged as follows,
bootelf 0x820000bc
Loading .rom_vectors # 0x82000000 (204 bytes)
Loading .text # 0x820000cc (224132 bytes)
EDIT :
When I try loading at address 0x81000000 It proceed further as follows,
bootelf 0x81000000
Loading .rom_vectors # 0x82000000 (204 bytes)
Loading .text # 0x820000cc (207960 bytes)
Loading .rodata # 0x82032d28 (7296 bytes)

Clearing .bss # 0x82035798 (313052 bytes)
## Starting application at 0x820000bc ...
But hangs after the above line. My ELF file size is around 1.9 MB. Will it make a problem?
Note: RAM size - 8 MB (0x80000000 - 0x88000000)
It shouldn't be hard. If you have an ELF file, bootelf will boot it.

I don't know how to use BOOT0 and BOOT1 to get into ISP mode. BOOT0 is connected to GND.
Post some information about your environment.
Are you using IAR EWARM? If you're not, you should download the size-limited trial version. Then, load one of the basic program examples, and try to flash it to your board.
What board are you using? And what do you mean you "closed" SWD and JTAG? I'm not sure what that refers to...jumpers? options window?
Help us out here.
