Two types of flash on the Juno's. I think Ben was talking about the SDcard flash? If so that can be replaced relatively quickly by replacing the SD cards either on failure or periodically ahead of failures.

Correct. Dave sent a earlier email explaining that we're seeing about 136 jobs before a failure. Which gives us about 2 weeks, before the SD card fails. Apparently, there were some known problems with the r0 sd card, that were fixed in the R2 design.

FYI we are buying the highest quality. Next call would be to reach out to Dean Arnold to see if they see same issues.

Best to talk to Dean Arnold and his team on how often as he manages Arm's LAVA farm. The on Juno board flash chip can also wear out eventually we have found over many years, they do after all have a finite life of reflashing. I did try as an experiment sending a Juno off to have its flash chip replaced on a Juno board (Approx £250) that had suspected on board flash issues but that did not help. Perhaps the board had other issues due to its age. Replacement Juno's cost £1200+ last I checked. They also don't make them any more I believe. However SD card failures are more often I understand.
