linux_spi - spispeed not affecting erase/write speed - MT25QU01G

[Mathijs Van de Poel]

Hello,

We are using the driver to write to a MT25QU01G memory over SPI.

I tried various speeds using the spispeed parameter but the erase/write
times stayed the same.

Any idea how I could improve this speed?

time sudo flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=100000 -c
"MT25QU01G" -E

time sudo flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=100000 -w
MT_file.bin -V -c MT25QU01G

Spispeed
