We use Appro DM8127 IPNC RDK 3.8.0 in our project, the default configure is 512MB DDR3,with two EMIF(EMIF0 and EMIF1),each is 256MB.
Now,we want to change to only use EMIF0 with 256MB DDR3. I try to change memory map 256M(single EMIF) as follows:
1、Not use Bank #2 in ti8148_ipnc.h
/**
* Physical Memory Map
*/
#define CONFIG_NR_DRAM_BANKS 1 /* we have 2 banks of DRAM */
#define PHYS_DRAM_1 0x80000000 /* DRAM Bank #1 */
#define PHYS_DRAM_1_SIZE 0x10000000 /* 256 MB */
//#define PHYS_DRAM_2 0xB0000000 /* DRAM Bank #2 */
//#define PHYS_DRAM_2_SIZE 0x10000000 /* 256 MB */
2、change LISA register
/*
* Program the PG2.1 DMM to Access EMIF0
* 256MB sections with not interleaving
*/
__raw_writel(0x0, DMM_LISA_MAP__0);
__raw_writel(0x0, DMM_LISA_MAP__1);
__raw_writel(0x0, DMM_LISA_MAP__2);
__raw_writel(0x80400100, DMM_LISA_MAP__3);
3、change the env bootargs:
setenv bootargs 'console=ttyO0,115200n8 rootwait=1 rw ubi.mtd=4,2048 rootfstype=ubifs root=ubi0:rootfs init=/init mem=54M vram=4M notifyk.vpssm3_sva=0x8F900000 ip=${ipaddr}:${serverip}:${gateway}:${subnet}::eth0:off ethaddr=${ethaddr} cmemk.phys_start=0x83600000 cmemk.phys_end=0x85600000 cmemk.allowOverlap=1 earlyprintk';saveenv
4、Boot log as below：
