Hello,

I have a problem on my board based on IMX28

Generally it works well, but sometimes I met kernel panic problem,

here is booting log.

Please give me a help and advice.

Thanks all.

Hi honguyp

I agree, probably more newer kernel may help.

Please look for example below

Use NAND-Flash with Kernel 3.2 on mx28evk

Best regards

Hi, Hongyup:

We meet the same problem in imx287, linux2.6.35, gcc4.4.4. I mean most of the time the system works well, only sometimes reboot will fail and we can see the error informations in serial bus. After power cycle, it will recover. It seems like that in gpmi_nfc_dma_go(), it waits for the dma_done flag, which will be set in gpmi_nfc_dma_isr(). When something goes wrong, isr doesn't work and kernel will be stuck in DMA error.

We are not familiar with the gpmi driver and maybe there are some bugs inside. Anyway we have tried some ways including reboot the kernel when DMA error happens, but can't figure it out yet.

We also try to contact with freescale's FAE, no response either.

If you have any updates for this please also let us know. Thanks.
