Marek, Some of our boards failed. I traced to this commit. Reverting this commit fixes the issue. I happen to have two boards with slightly different flash chip. One works and the other doesn't. The working board has => fli Bank # 1: CFI conformant flash (16 x 16) Size: 128 MB in 1024 Sectors AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E2801 Erase timeout: 2048 ms, write timeout: 1 ms Buffer write timeout: 3 ms, buffer size: 512 bytes The failing board has => fli Bank # 1: CFI conformant flash (16 x 16) Size: 128 MB in 1024 Sectors AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E2801 Erase timeout: 4096 ms, write timeout: 1 ms Buffer write timeout: 3 ms, buffer size: 64 bytes Can you investigate?
