We are facing issue in DDR bring-up of 2019.04 version where the U-boot is hanging while doing 4GB DDR initialization.
With the above 2 steps, the U-boot version 2018.03 is working fine however, 2019.04 U-boot is hanging. Please find attached U-boot logs for the same and the DDR calibration image that I have used and the patch that we have used for 4GB DDR change.
Thank you for the response.
one can try with latest uboot and linux
As per your suggestion, I have compiled the U-boot of imx_v2020.04_5.4.24_2.1.0 and applied the patch for 4GB and I am getting a proper U-boot prompt. However, I am getting the attached crash in the kernel.
Please find attached the U-boot patch and detailed logs (crash_logs.txt) that I am getting.
Patches over U-boot
1) Patch for 4 GB configuration => 0001-uBoot-Add-4GB-DDR-memory-support.patch
2) 4GB DDR settings (Generated with the RPA_v24) => lpddr4_timing.c
for that version patch is not needed, as it is already included in release.
Recommended to try latest RPA tool from link
First try to build image without OpTee as described in sect.5.6.10 OP-TEE enablement
