How is maxsize defined in your configuration?
maxsize is configured as, #define CFG_MAX_RAM_SIZE 0x08000000 /* 0 .. 128 MB of (S)DRAM */
Try doubling it ;-)
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
Umm.. this seems bogus to me. If the actual size is != MAX_RAM_SIZE thenyou will have a hole in your mapping; this is not what you want to do. See the README how to handle such a situation.
BTW, is it right by simply halving the MAX value ? I sort of guessed
No, this is ... bogus.
this part. Looked at schemetics and they used 2 chip selects. So, I figured halving it. Is it cool ?
Definitely not.
