Hello,
I want to use the ECC feature of LPDDR4 memory with i.MX8MP. To do that, I enabled inline ECC with the i.MX 8 Register Programming Aid (RPA) tool and reflected the changes in lpddr4_timing.c. Then, when generating U-Boot, I set Device Drivers -> i.MX8M DDR controllers->imx8mp inline ECC to Enable in menuconfig.
However, the following message is displayed when booting the Yocto Linux kernel, and the ECC feature is not enabled.
Please tell me if there are any missing steps or settings to use the ECC and EDAC features.
