Hi,
How are you?
I am trying to coreboot an Asus A88XM-E. The chip on that motherboard is GD25Q64(B), which I execute sudo flashrom --programmer ch341a_spi -w coreboot.rom, I got this error: flashrom v1.2 on Linux 5.9.14-rockchip64 (aarch64) flashrom is free software, get the source code at https://flashrom.org

I got new GD25Q64 chips from aliexpress. The verbose version is like this:
