Flashing NAND using JTAG

[gatelogic]

Hi,

I have a custom i.MX28 board without SD / USB client, and want to flash the NAND via JTAG.  I'm currently using OpenOCD with the Olimex ARM-USB-OCD JTAG interface.

It appears that there's no current support in OpenOCD for the GPMI-based NAND access used on the i.MX28, which leads me to ask if anyone has used other tools to do the job, or indeed modified OpenOCD to handle it?

Hi Alister,

did you get any response to your question?

I have the same question and did not find any answer.

best regards

Alister, Jan

If you are using OpenOCD, once you halt the SoC soon after

reset, you might be able to load ram version of u-boot and

provided that your NAND flash is supported in u-boot, you

would be able to program your NAND. I didn't try this but I

believe it would work.

Hope this helps
