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.
EDAC MC: Ver: 3.0.0
EDAC MC: ECC not enabled
Please tell me if there are any missing steps or settings to use the ECC and EDAC features.
