RFSoC 4x2 not booting

Support
1

Hi,

Out of nowhere my RFSoC 4x2 won’t boot properly. Whenever I turn it on, the board seems to boot normally for one second, then it kinds of reboot and tries again, the LEDs blink rapidly and the fan starts spinning, stops and starts again. It’s better to see in a video:

This repeat indefinitely. What I’ve tried is:

  • Change the power supply with one from another RFSoC, same result
  • Change the SD card for one that I know it works in antother RFSoC, same result
  • Contact RealDigital, but they won’t answer my emails nor my calls

Does someone have any idea, what type of failure could this be?

Hi,
If I understand correctly, you took another SD card, reburned in it the image from PYNQ supported boards and PYNQ pre-built images | PYNQ, put it in your board, selected the boot option “sd card” and retried to turn on the board? And it still not loads, nothing is displayed via the led screen?

That is correct. With new image, and power supply, the board won’t boot, it will just blink the LEDs and spin the fan for 1 second, and repeat (see video). It seems to be a hardware problem.

Dear @franco,

Based on your description, the board seems to be faulty.

Please try contacting RealDigital again, if they do not reply in a few days contact the AMD University Program.
