MCU-PLUS-SDK-AM243X: am243x EVM: GEL-script is not able to initialize DDR

Part Number: MCU-PLUS-SDK-AM243X

Hello,

I have problems with initializing the EVM board. It is not possible to initialize the DDR RAM. I followed all the instructions on https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/CCS_SETUP_PAGE.html#CCS_NEW_TARGET_CONFIG and https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html for the DEV BOOT MODE.

The documentation says it will initialize the DDR with the launch-script but I do not see the mentioned GEL-file-output:

There is NO DDR initialization.

When I try to manually enable DDR via the GEL-scripts (ECC disabled) the following happens:


and it hangs here forever. The output looks like in the documentation but it just won't proceed.

What should I do now?

Best regards

Felix

    Hi Felix,

    For some reasons, the initialization DDR using load_dmsc_hsfs.js and GEL file do not work anymore. I will report this issue to the software team (a JIRA ticket has been filed). Meanwhile, can you use the SBL_NULL to initialize the DDR? I have tested it. It works on AM243x EVM.

    Best regards,
