I'm using a board similar to ecotea here's the initial prompt. So initailly it had 256 mb ddr sdram. now i want to use 512 ddr sdram. i put that part in and now i get this error.
So to sum up, 256MB i working (U-Boot get's to the prompt) and 512MB is not working. Right?
the error is generated in program_tr1() in cpu/ppc4xxx/spd_sdram.c here are some questions
- what exactly is this program tr doing. i guess cp
No. It's doing a simple memory test do determine a common TR1 value for all installed memory bank's. Please see the 440GX users manual for more details.
- Can someone gimme any pointers as to what's that problem here.
Not easy to say. Could be a hardware problem. Could be still a bug in the 440 SPD-DDR setup routine. Did you try a module from another vendor?
- why isn't program_tr0 used at all ?
It seems to be used for me. Please look again.
