It could be that XMC chips aren't officially supported yet, but there
are some unofficial flashrom patches for XMC support available online.
Please try them.

Hi Mike

i have compile last git source an make a read -test

yesterday have i testet it with old version . this has "Found Unknown flash chip "SFDP-capablechip" (8192 kB, SPI) on ch341a_spi.
and data was also read out.
then I had to repeat the read process to a new file and check with diff command that recognized differences.

today with aktual git source "flashrom v1.2-230-gc193fbd" 
the unknown Unknown flash chip "SFDP-capablechip" also appears.
but the reading tests showed that no more differences were recognized.

I found a post in another forum:
>

I've de-soldered chip  XMC QH64AHIG (XM25QH64AHIG)
In attachment you can find dump from flashrom
Also I've found that, this chip is equals to :
XM25QH64AHIG GD25Q64CSIG MX25L6406EN2I-12G EN25QH64A-104HIP W25Q64JVSSIQ
<

an make  test 'flashrom --programmer ch341a_spi -f -c "GD25Q64(B)" -r XMC_XM25QH64AHIG.bin'
with the same result. flashrom can read chip.
I couldn't write test yet because I have to revise the flash first and remove all of the China spyware from the firmware.

greetings Winfried

further development purposes.

The only reliable way to "remove all of the spyware" from your
firmware - is to switch to the opensource coreboot BIOS with as few
binary blobs as possible. (By simply removing some UEFI modules you
could't guarantee the security, I hope you understand this). If your
PC isn't supported by coreboot: either try to port a coreboot to it if
it's possible, or sell it and buy a supported PC with that money.
