Hello,
I have a tablet on NM10 chipset and AFU says it has EON 25F/Q/QH chip 16Mbit size. But flashrom don't even probe for SPI chips.
GCS = 0x10c60: BIOS Interface Lock-Down: disabled, Boot BIOS Straps: 0x3 (LPC)
Is it possible to force SPI interface somehow? Verbose log attached.
Since the lockdown is disabled one could in theory change the interface used I think (I have never looked into it in detail). *But* this would not help you: the flash chip is most probably behind the embedded controller which is not supported yet by flashrom. The EC translates between the SPI bus used by the flash chip and the LPC bus used by the NM10. It also probably uses the same flash for its own firmware, which is one of the reasons why supporting such devices is a bit hairy.
