Hi, I've got a APU2.e PCB with a AT25SF641 for the serial flash (flash PN based on looking at the PCB). Trying to run flashrom (via a Debian live usb stick...I'm having no issues with APU2 booting accessing serial console) as follows yields a lot of output, but nothing useful...is this expected with a AT25SF641?
Other people commenting on the interweb with the APUs seem to be seeing Winbond (and no issues)
Found Winbond flash chip "W25Q64.V" (8192 kB, SPI) mapped at physical address 0x00000000ff800000
Any thoughts are greatly appreciated Jon
