I have problems getting a dual-channel LPDDR2 (2x512MB) configuration to work with i.MX6Q.
The board is currently running and works fine except that I only have access to half of the RAM (512MB).
I added my U-Boot cfg-file to this question.
I've set the BOOT_CFG3[5..4] to 01.
U-Boot is 2015-01
Some U-Boot definitions:
#define PHYS_SDRAM MMDC0_ARB_BASE_ADDR
#define PHYS_SDRAM_SIZE (1024u * 1024 * 1024)
#define CONFIG_NR_DRAM_BANKS 2
#define CONFIG_SYS_SDRAM_BASE PHYS_SDRAM
Can you help me?
What other information do you need?
