Hi,

I have test on mx23evk board. Still see the same issues.

Hi,

Thanks for your test.

Hi,

It's not really working for me.
I've applied all gpmi-nand driver patches and the dma driver patches.

I have added following kernel parameters:
mtdparts=gpmi-nand:20m(boot),-(user) ubi.mtd=1 root=ubi0:rootfs0
rootfstype=ubifs gpmi_debug_init

During boot I get already get DMA timeout:
[    2.560000] [ start_dma_without_bch_irq : 392 ] DMA timeout, last DMA
:1
[    3.560000] [ start_dma_with_bch_irq : 427 ] bch timeout!!!
...
(see log file in attach line 89)

I still see this DMA timeout when booting.
What kernel parameters do you use? I still use same as above.

Do you have an SD card in the system? I'm getting the same error when
accessing an SD card. Without SD card I can use the flash without any
errors.

No SD card in the system. At least not on my mx23evk board.
My real target hardware has a SDIO wifi chip.

Does it conflict with the GPMI?

Are you also testing on the mx23evk board? Really strange it is not
reproducible here then.
Anyone using mx23evk please give:

I tested the code in mx23evk.
After boot the kernel and login the shell, I met a problem:
  the flash_eraseall can not run with the log:
"Floating point exception"
:(

- revision number of board (I have tested on rev C1)

Revision number is C.

- kernel parameter used (see previous mail for mine)

"console=ttyAMA0,115200 root=/dev/mmcblk0p1 rw rootwait gpmi_debug_init"
