imx6 nand driver using ecc on bsp

mrshafie — Mon, 19 Apr 2021 07:49:59 GMT

Hello.

i'm writing imx7 nand driver. i have no idea how to do it, so i read imx7 reference manual and nand driver that wrote for imx6 bsp. but that driver use c++ object oriented architecture for implement command chain. and i want to use c for that. so i rewrite it by c language and all thing is ok except ecc write and ecc read.

so my problem is: is Nand ecc write/read in imx6 bsp work? is it ok?

i have this problem because i saw dumpchain in ecc write/read sectioin that maybee this code is not ok and maybee buggy ..

in other words, I rewrite Nand driver in C and and raw Nand read/write is ok and work correctly. but ecc didn't work, its interrupts called and all thing seems is ok but data not read successfully.

Hi Hdggd

for imx7 nand driver one can look at i.mx28 (it is the same) baremetal example (../drivers/nand)

On-Board Diagnostic Suit for the i.MX28
