Hello, in order to understand the process of adapting imx8mp to LPDDR4, I configured the timing of LPDDR4 myself on the imx8mp evk development board.
My uboot version is 2022.04. I use the default ds file MX8M-Plus_LPDDR4-RPA-v9.xlsx and generate the corresponding code through mscale-d dr_tool-v3.31_setup. exe. My DDR stress test has passed. Currently, there are the following issues:
1. My uboot has not compiled board/free scale/imx8mp_ evk
/The lpdddr4_timing. c file is compiled as board/freescale/imx8mp_ evk
/DDR4_timing. c file.
2. There is a document in mscale-d dr_tool-v3.31_setup. exe that introduces the existence of new and old versions of uboot. May I ask if my version is the new version or the current version, and whether I should use the file lpdddr4_timing. c.
3. How should I generate LPDDR4 timing for uboot 2022.4 and run it on the imx8mp evk development board.
你要编译lpddr4,那你应该是 make imx8mp_evk_defconfig,你那个配置是对应ddr4
