This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE
The chip is mx25L6406EZNI-12gf which I assume
would use
Macronix MX25L6406E/ PREW 8192 SPI
The command that gets the generic message is
sudo flashrom -r oldefi1.bin -V -p linux_spi:dev=/dev/spidev0.0
please see our FAQ[1]. You are running the SPI bus at an unknown (likely much too high) clock.
I put exactly what is listed as type and says unknown…
pi@pi0w:~ $ sudo flashrom -L | grep MX25L6406E/ Macronix MX25L6406E/ PREW 8192 SPI
Looks like somebody put a line break into the identifiers... you'd have to write "MX25L6406E/MX25L6408E"; it's one entry for both chips. But that would only help if flashrom could detect the chip.
