Hi,
I would like to change DDR size from 128MB to 256MB on DM368IPNC_IMX036 ver 2.0.0 reference design based board.
What software changes need to be done.
I looked at u-boot code in davinci_dm368_ipnc.h :
/* Memory Info */
/*=============*/
#define CFG_MALLOC_LEN (0x40000 + 128*1024) /* malloc () len */
#define CFG_GBL_DATA_SIZE 128 /* reserved for initial data */
#define CFG_MEMTEST_START 0x82000000 /* memtest start address */
#define CFG_MEMTEST_END 0x90000000 /* 16MB RAM test */
#define CONFIG_NR_DRAM_BANKS 1 /* we have 1 bank of DRAM */
#define CONFIG_STACKSIZE (256*1024) /* regular stack */
#define PHYS_SDRAM_1 0x80000000 /* DDR Start */
#define PHYS_SDRAM_1_SIZE 0x8000000 /* DDR size 128MB */
Is there sufficient just to increase PHYS_SDRAM_1_SIZE to 256MB.
Do i need to change any other code in bootloaders or Linux.
Best regards,
Marko.
