After restore: chain[5] PIC fw version=0x00
I have had this issue with multiple S9s. Sometimes chains 5 and 6 will have fw=0x03 and chain 7 will have 0xf1, for example, and the pic flash errors are only on that chain.
This problem obviously blocks the machines from mining, although they stay on with stable api and not rebooting. How can I address the PIC needing restoration? Is the issue here with the flash or the firmware? Is it unable to restore fw due to flash error?
