New DreamPlug Hardware ?

[Juanjo]

Got a new batch. And it seems that instead of 2MB Flash SPI now it comes with 512MB NAND FLASH and new uBoot version.

I was able to copy my Kernel (from FAT partition) to Flash as in a GuruPlug tutorial. Problem is that this new uBoot seems to get stuck scanning BUS with certain USB Mass Storage devices plugged

I would not expect any of my kernels to work with NAND flash.
However,  sheeva kernels might now be a better fit for the dreamplug.

[Juanjo]

Actually they do but NAND MTD isn´t detected.

I modified the kernel (dreamplug-setup.c) to include Orion NAND but it doesn´t detect the NAND either

[spinifex]

Not sure which is the biggest problem, 

Your specific problem or how to provide a generic Dreamplug kernel?

[Juanjo]

Actually 512MB flash isn´t bad.

The real problem with this new batch is the buggy uBoot they used, it cannot boot from external SD and it hangs with some USB storage devices. I booted with a GuruPlug uBoot and it starts and recognize the NAND, so I started to compile a new uBoot which is a DreamPlug uBoot with bits from GP board definition to allow NAND, so far it compiles and loads but it cannot see the NAND and I´m a complete noob with uBoot

Since kernel is modular I think it can be modified to support SPI NOR and NAND on the same Kernel but it seems hard to do the same on uBoot in order to have a generic DP uBoot too

BTW it also comes with rootfs on NAND flash... UBIFS fs

[spinifex]

So does it still have an internal uSD?

[Juanjo]

So does it still have an internal uSD?

Yes. But it´s empty. The kernel and rootfs is on the NAND.

Since the GP uBoot recognize the NAND. A Kernel modified to have GP NAND partitions and Orion NAND should work but I don't know why it doesn't detect the NAND chip (Samsung 512MiB NAND, 8bits)
