Description

I know it's a bit of a longshot, but any chance of getting support for the F50L2G41XA (2B)?

Hello? @lehjr ! Today IMSProg can only work with SPI NOR FLASH chips. Your chip is SPI NAND. I am only thinking about SPI NAND Flash memory support for now. This is planned in future.

Hello, @lehjr ! Please build and test version 1.7.1 of the main branch...

Unfortunately, I wasn't able to read the chip because there is no option to toggle ECC on or off. There is a fork of SNANDer that has support for the chip at (chip actually appears to be a clone of MT29F2G01ABA). https://github.com/Droid-MAX/SNANDer

With that fork and using the "disable ecc" option, the chip will read, without it, reading fails. Of course reading a chip this size takes hours. CH347 is probably a better option but software support hasn't caught up yet.

I took a quick look at the datasheet for this chip. It has many non-standard commands for SPI NAND flash memory. For standard SPI NAND flash memory chips, you can disable ECC using the “Chip Information Menu” ([CTRL] + P ). Here you can change bit 4 in register two.
