Thanks for the hint. You are right I left out configuring memory controller. Okay, now I've configured it, but it's still playing up on me.
How is maxsize defined in your configuration?
maxsize is configured as, #define CFG_MAX_RAM_SIZE 0x08000000 /* 0 .. 128 MB of (S)DRAM */
How is your memory controller configured (address masks) ?
#define CFG_BANK0_START 0x00000000 #define CFG_BANK0_END (CFG_MAX_RAM_SIZE/2 - 1) #define CFG_BANK0_ENABLE 1 #define CFG_BANK1_START (CFG_MAX_RAM_SIZE/2) #define CFG_BANK1_END (CFG_MAX_RAM_SIZE - 1) #define CFG_BANK1_ENABLE 1
Rest is all disabled.
It gets to DRAM: 128MB, but soon after that, it wants to access 0x7FDEEB0, where there's no data. Looks like its configuration issue. Guess I should look into it.
BTW, is it right by simply halving the MAX value ? I sort of guessed this part. Looked at schemetics and they used 2 chip selects. So, I figured halving it. Is it cool ?
