Dear NXP Technical Support Team,
I am currently attempting to utilize the Inline ECC feature on the IMX8MP(Follow the steps in AN13566.pdf and https://community.nxp.com/t5/NXP-Tech-Blog/xxx ). According to section 9.2.5.1.20.3 of IMX8MPRM.pdf, I attempted to set ecc_region_parity_lock to Unlocked.
I modified the content of lpddr4_timing.c and set the value of the 0x3d400074 register to 0x780.
struct dram_cfg_param ddr_ddrc_cfg[] = {
{0x3d400304, 0x1},
{0x3d400030, 0x1},
{0x3d400000, 0xa3080020},
{0x3d400020, 0x1323},
{0x3d400024, 0x1e84800},
{0x3d400064, 0x7a0118},
{0x3d400070, 0x070277D4},
{0x3d400074, 0x780},
......
However, the register value read via the memtool tool is 0x790.
root@imx8mp-lpddr4-evk:~# /unit_tests/memtool 0x3d400074 1
E
Reading 0x1 count starting at address 0x3D400074
0x3D400074: 00000790
I would like to know how to properly configure this register.
Thank you in advance for your support.
