We are developing the LX2160A board. However, there is a problem in setting and proceeding as follows.
DDR uses DDR4 (P/N: MT40A512M16) with On Board Memory
The code modification is as follows.
1. plat/nxp/soc-lx2160a/lx2160ardb/platform.mk CONFIG_STATIC_DDR :=1
The following three contents were tested while making changes.
NUM_OF_DDRC := 1
DDRC_NUM_DIMM := 1
DDRC_NUM_CS := 2
2. plat/nxp/soc-lx2160a/lx2160ardb/ddr_init.c
const struct ddr_cfg_regs static_1600 = {
.cs[0].bnds = 0x3ff ,
.cs[1].bnds = 0x3ff ,
.cs[0].config = 0x80050422,
.cs[1].config = 0x80000422,
.timing_cfg[3] = 0x13622100,
.timing_cfg[0] = 0xf1aa0018,
.timing_cfg[1] = 0x646a8844,
.timing_cfg[2] = 0x58023 ,
.sdram_cfg[0] = 0x65044001,
.sdram_cfg[1] = 0x401001 ,
.sdram_mode[0] = 0x6010c50 ,
.sdram_mode[1] = 0x280000 ,
.interval = 0x30c00000,
.data_init = 0xdeadbeef,
.timing_cfg[4] = 0x4502 ,
.timing_cfg[5] = 0x7401400 ,
.timing_cfg[7] = 0x3bb00000,
.zq_cntl = 0x8a090705,
.sdram_mode[1] = 0x500 ,
.sdram_mode[1] = 0x10240000,
.timing_cfg[8] = 0x9448c00 ,
.dq_map[0] = 0x32c57554,
.dq_map[1] = 0xd4bb0bd4,
.dq_map[2] = 0x2ec2f554,
.dq_map[3] = 0xd95d4001,
};
const struct dimm_params static_dimm = {
.rdimm = 0,
.primary_sdram_width = 64,
.ec_sdram_width = 8,
.n_ranks = 2,
.device_width = 16,
.mirrored_dimm = 0,
};
After setting as above, the following problem occurs.
When setting up the PHY, it is judged to be a problem in the place. Is there a way to solve this?
