[flashrom] Unrecognized flash

[Ron Knapp]

Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on linux_spi.
Probing for Generic unknown SPI chip (REMS), 0 kB: probe_spi_rems: id1 0xf0, id2 0x7
Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI).

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

I put exactly what is listed as type and says unknown


***@pi0w:~ $ sudo flashrom -L | grep MX25L6406E/
Macronix MX25L6406E/ PREW 8192 SPI
***@pi0w:~ $ sudo flashrom -r oldefi1.bin -c "MX25L6406E/" -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.

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.
