I have see SD cards become corrupted, and thus unbootable. Do you have another SD card you can try?
Also, rather than using the prebuilt option for PetaLinux JTAG boot, can you try simply booting to u-boot instead?:
petalinux-boot --jtag --fpga --bitstream ./images/linux/system.bit --u-boot
(don't forget to move the boot mode switch to JTAG!)
This obviously won't boot the full OS image, but it can be a quicker test that the processing system and programmable logic are OK. I have see that the prebuilt option does not always work as desired or expected. If you can get to a u-boot prompt there is a good chance the hardware is OK and you can focus debug elsewhere.
Thanks for the feedback, I tried another SD card but it is not working
The command you mentioned gives following error :
INFO: Configuring the FPGA...
INFO: Downloading bitstream: ./images/linux/system.bit to the target.
fpga initialization failed
I tried also with Vitis to download the bitstream, ext ... but the board is not detectable.
If you are using a VM, you might check this suggestion from the Xilinx forum:
My only other thought is that your board has been damaged.
Are you able to read the uSD card from another system, mainly a Linux system? This could also give you an idea if the filesystem is corrupt or there is an issue with the uSD card itself.
Also, there seem to be notes regarding Samsung EVO uSD cards not being supported with the Ultra96 boards, especially those over 64Gb. However, I am using both Samsung Pro+ 64Gb and Samsung EVO Plus 64Gb without issue thus far.
I have seen issues where the uSD card was not seen on a board as a result of a damaged uSD card holder. You might want to check the slot for the uSD card and ensure there are no obstructions or damaged pins in the slot.
I was normally booting my Avnet Ultra96 V-2 from SD-card but today surprisingly no more.
- I am booting from the same SD card and the switch is correctly configured
- No output on the serial Interface
- The Led D5 INIT(red) is always illuminating
- The led D2 3,3V (Green) is always illuminating
- The led D1 (DONE) is never illuminating
- the leds D3,D4,D6,D7 always illuminating
- Clicking on the button SW4 (PWR_BTN) doesnt trigger a restart (I guess so because I remarked that the leds are always illuminating).
I tried to change the SD-card but the same status remains.
I tried to boot it from JTAG using petalinux-boot --jtag --prebuilt 3 --verbose, it ends up with the error "no targets found with "name = ~"*PSU*" . available targets :
1 PS TAP
Can you please give some hints too debug the problem, that would be really helpful.
