Hi!
Our custom board based on IMX6ULL evk and it uses LPDDR2 2gb
we need to custom our uboot and linux
in the mx6ull_customboard.h (uboot )
i changed the size of ddr
#define PHYS_SDRAM_SIZE SZ_2G // for 2 Giga
should i change next parameters
#define CONFIG_NR_DRAM_BANKS 1 // my memory has 8 bank
#define PHYS_SDRAM MMDC0_ARB_BASE_ADDR
should i change these 2 params numbers of banks and physical address?
Thanks
Hi Vladimir
if board is based on nxp evk design I believe these settings
can be left in default state. It is necessary to run ddr test
i.MX6/7 DDR Stress Test Tool V2.80
and change uboot/../mx6ullevk/imximage_lpddr2.cfg with new calibration
coefficients found from test.
Best regards
igor
