Hi ALL
We are facing one issue related to the memory allocation on DM365 based
board. We have 256MB DDR on our board.
But when we allocate more than 128 MB of memory to the kernel (in
bootargs), sometimes kernel gives paging request errors while running
application or sometimes it is not able to even boot (i.e. kernel panic).
We have done changes in the U-boot to configure the DDR of 256MB.
We have modified the following U-boot source file:
File: include/configs/davinci_dm365_evm.h
Change: (As below)
#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 */
// ORIGINAL: #define PHYS_SDRAM_1_SIZE 0x8000000 /*
DDR size 128MB */
#define PHYS_SDRAM_1_SIZE 0x10000000 /*
DDR size 256MB */
Details of our DM365 board is as follows:
* Silicon Version of DM365: DM365ZCE30
* DVSDK Version: dvsdk_2_10_01_18
* Linux Version: linux-2.6.18_pro500
* PSP Version: PSP_02_10_00_14
* DDR Size: 256MB.
Any body help me what are the changes are still left?
Is there any missing in setting?
What are the setting if we go from 128MB ddr to 256MB size of DDR?
Thanks
Hitesh Patel
