Yes, it is fairly new I suppose. Is there any way I can install the spidev kernel module manually? At least then I would be able to use flashrom.

So, chipsec does not know how to access the SPI part because the platform is not supported by the tool. To dump the SPI device it must access the SPI controller and this is platform dependent. Other tools may be having similar issues if this is newer hardware.

problem dumping bios
by Healer64
I am trying to create a secure backup of bios + all option roms for integrity verification purposes. However I cannot dump the bios. I have tried the following commands:
Chipsec_util spi dump rom.bin
Chipsec_util spi read 0x700000 0x100000 bios.bin
I get the error "SPI cycle not ready. SPI flash didn't return any data (turn on verbose)"
I've also tried using flashrom and get the error "cannot get target bus from programmer. Programmer initialization failed"
When I check /dev I don't see any spidev0.0. Does chipsec require an spidev? Is there another way to dump rom?
