Help please with uboot GoFlexHome (no replies)

Hi there,

I've got a 2TB goflex home that I'm attempting to understand - unfortunately it's off (inter)network, I don't have JTAG ICE, but have added a serial port (based on an original Nokia CA-42 - all I had around, building an RS232 level shifter when I've finally finished the board). The Nokia cable doesn't show a serial port until the GFlex has powered up (so that causes some headaches firing up a console fast enough to interrupt the boot process)

Anyway, not wanting to brick the device, I decided to download davygravy's uboot for the goflex home - I load it in via tftp (according to jeffs instructions) and then tell it to go - it immediately goes into error and resets the CPU.

After dumping the nand and doing a checksum, it doesn't match any of the MD5's of the supported goflex devices.

I've also tried compiling the latest version of uboot (u-boot-2013.07.rc2) as this has support for the goflexhome built in (supposedly), this does something very similar (i.e. resets the CPU)
