32MB Fuze V1, Checksum error

(1/9) > >>

sss:
I upgraded my Fuze to 32MB of SDRAM and now when it tries to load the firmware, it says, "Bad Checksum"
(Checksum: 3A27276 Sum: 1E60F0D Length: 91B14   ;D I knew it would bite me with some sort of error with a ram upgrade)

What exactly do I need to do to compile the bootloader and firmware to work with my upgraded fuze v1?

If I also upgraded a fuze v2 in the future, would anything else need to be done (additionally)?

saratoga:
You just soldered a new memory module in place?  Are you sure its compatible? 

sss:
I am trying to find that out  ;D  It was difficult to find 512MB DIMMs of SDRAM and before I go out and try another, I would like to see if the chips I have work first. 512MB /16 chips = 32MB per chip.  With hot air, soldering is pretty easy.

saratoga:
I would find the datasheet for your chip and verify that its electrically compatible with the one you took off, then check if the logical organization of the module is different. 

sss:
Saratoga, are you saying that if I put a verified, perfect replacement on, I should be able to boot the Fuze like nothing happened and Rockbox will see the 32MB of RAM without compilation of a new firmware and bootloader??  Are you sure?
