Zynq7000 Zedboard "Erase while flasing the device"

[maska989]

A couple of weeks ago in the process of testing "on bench" we encountered a problem with Zynq 7000 Zedboard (Fresh units). Even today on GitHub-CI (direct link) same problem appeared namely it is all about "ERROR WHILE FLASHING THE DEVICE".

This problem is hard to reproduce (it's showing up something like once on 50~60 runs) and sometimes is easier to get other (maybe related to this) problem with jffs2.

Commit SHA used to reproduce: (commit c4c322a75b1333f4797fad184c313dd2feebee64)

• What's going on in the screenshot:
  • On the left-upper corner we had our runner which encountered a problem with erase flash0 in the first case we were looking for a maybe bigger timeout on this in case zynq is likely to slow down, but that wasn't the solution.
  • On the right-upper corner we had dmesg -w running and it's looking like USB connected to Raspberry couldn't recognize zynq plo USB even if it had a couple of times it tries to reset the assigned.
  • On the left-down corner we tried to check if it was right what the dmesg says and what USB connection was missing.
  • On the right-down corner we used Picocom to connect to zynq to look inside what is going on and found out that Plo is up.
