[flashrom] erase algorithm on Macronix MX25L6406E

[Arian Sanusi]

Hi all,

I have a T420 with Macronix MX25L6406E flash. flashrom's first erase algorithm fails, the second succeeds, which is obviously not fatal, but means an unimportant (internal flasher), annoying (raspi) to painful (arduino) delay. Would be awesome if the second erase algorithm could be default for this chip!

best regards,

Arian
