I'm pretty interested. NAND on the pxa320 is proving to be a painto us.
It seems I'd forgotten to cc' the list on my reply to Daniel so I've fw'ed that on now - see that msg for some of the details and the source.
It should work ok for the pxa320 but I think there is a #define that needs changing because the controller clock speed is different. I think the docs said that that was the only difference.
What's your boot sequence look like?
Not much at the moment, I've just been playing with it. Currently I let the OBM load u-boot from flash and then u-boot loads the kernel off of the MMC card because I'm having problems with JFFS2 on the NAND within linux itself (Is JFFS2 supposed to be that slow??).
Are you using the mobm from the BSP?
Bear in mind this is an iPAQ so a complete retailed system. I can't get any help or info from Marvell or HP so I'm doing everything by poking it and seeing.
If the MOBM is what I know as just the OBM then yes, but it's the winCE one (they are apparently slightly different). The OBM loaded the winCE bootloader from 0x40000-0x80000 in the flash to 0x83C00000 in RAM. I've just put U-Boot there and let the OBM load it up. The other advantage being that the MMC and NAND MFP configs and basics have already been set.
I daren't touch the OBM because I can't reflash the device if it fails to boot and the OBM lets me boot off of the MMC card (it's "diagnostic function") if I wipe the later boot stages.
Are you using the nand_spl from u-boot?
Not sure what that is. I'm afraid I'm still on the learning curve as I only saw u-boot for the first time on Thursday and hadn't touched the NAND flash before the weekend before.
Hope that helps,
