On my board SDRAM is 2 chip 2*256Mb
MT48LC16M16A2 â?? 4 Meg x 16 x 4 banks
I set define
#define SDRAM_SIZE 0x04000000 // 64MB
#define IXP425_SDRAM_CONFIG_INIT (SDRAM_CONFIG_CAS_3 | SDRAM_CONFIG_2x16Mx16)
The IXDP SDRAM controller has to refresh the 8192 rows each 64 ms which
means one refresh each 7.81us. At 533Mhz it means ~ 4162 cycles which is
0x1042.
#define IXP425_SDRAM_REFRESH_CNT 0x1042
#define IXP425_SDRAM_SET_MODE_CMD SDRAM_IR_MODE_SET_CAS3
It is correct?
