Hello,

I am trying to use Linux Kernel from SDK 6.3.0.106 and having problem with the nandflash command.

on SDK 4.0.0.4 I was using the following:

flash_erase /dev/mtd3 0 0

nandwrite -p /dev/mtd3 dataFile

On SDK 6.3.0.106:

flash_erase /dev/mtd3 0 0

nandwrite -p /dev/mtd3 dataFile

There is no error as such, but the nandwrite command on SDK 6.3.0.106 is v2.0.2 but in SDK 4.0.0.4 its v1.5.2

SO my question, how to find what is the page size set to, please. thanks

Hi Mitesh,

Sorry to notice you are facing issues on NAND flash command. I checked this with Linux Experts on this and gathered the information for you as below.

By the way, what is the SOC you are facing issue with? Is this K2E EVM?

$ mtdinfo -a

should help. “Minimum input/output unit size” for NAND should correspond to page size.

See example here: https://unix.stackexchange.com/questions/184284/nand-flash-mtd-ubi-total-space

-Thanks,

Aravind

Hi Aravind, I am using OMAPL138 SoC. the nandwrite command on SDK 6.3.0.106 is different to SDK 4.0.0.4 and not sure if that is the cause of the error.

thanks
