[flashrom] flashrom Verifying FAILED

[Servus]

Hi!
 
I get this error very often:
 
flashrom v1.2 on Linux 5.10.78-7-osmc (armv7l)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found GigaDevice flash chip "GD25Q64(B)" (8192 kB, SPI) on ch341a_spi.
Reading old flash chip contents... done.
Erasing and writing flash chip... Erase/write done.
Verifying flash... FAILED at 0x00008790! Expected=0x44, Found=0xff, failed byte count from 0x00000000-0x007fffff: 0xcc60
Your flash chip is in an unknown state.
Please report this on IRC at chat.freenode.net (channel #flashrom) or

Any ideas?
