Interestingly I had flash_readtest running in a loop the whole weekend without any errors. Although this test does not verify the data read so it could point towards a controller / driver problem. I'm in the process of upgrading the SDK from 2017.3 to 2019.2 to see if that makes any difference Thanks, /Otto On Fri, Nov 22, 2019 at 1:53 AM Richard Weinberger wrote: > > On Thu, Nov 21, 2019 at 8:54 PM Otto Blom wrote: > > > > Hello All ! > > > > A couple of updates on this problem.
