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.
the error is generated in program_tr1() in cpu/ppc4xxx/spd_sdram.c
here are some questions
1) what exactly is this program tr doing. i guess cp
2) Can someone gimme any pointers as to what's that problem here.
3) why isn't program_tr0 used at all ?
Any inputs are appreciated,
