why the kernel can not match driver for norflash on DM6467 ?

Hyman Yu

Hi everyone,

I was stuck in a bad situation. I wanted to make my kernel to mount jffs2 file system on norflash,and I did it with a low edition kernel,on that point,the kernel worked well and could mount the jffs2 successfully. But,when using another high edition kernel,in fact we just added some new drivers in this kernel ,I found the kernel never mount the jffs2.The following information was printed on the console.

nor_davinci: probe of nor_davinci.0 failed with error -6

From my perspective,the kernel find norflash but can not match a driver for it.But I am sure the MTD driver is normal and the kernel supports jffs2 as the low edition kernel does.

So,where is wrong?Please help me!

Hi,

DM6467 EVM from TI does not have a NOR flash. Are you using a custom board which has DM6467 chip on it?

Error number -6 corresponds to ENXIO. Search for ENXIO in the NOR flash driver source code and debug why the driver is returning this error code. I doubt, you might have enabled some other driver which cannot co-exist with NOR flash driver.

Hi Sudhakar，

Thanks a lot,as you know,this problem has troubled me for 3 days.I could not find the answer myself.

But with your remind,I finally find that,my nor flash co-exists with ATA driver.

This is where the error ocours!

I feel really grateful to you!
