PROCESSOR-SDK-AM62X: AM62x DDR test tool?

Tool/software:

Hi - I'm investigating a problem where some of our AM625 boards are not booting. One possible cause could be a problem with the DDR. Is there a tool, or similar, I can use to verify, or stress-test the DDR memory?

I'm aware that u-boot has such a feature but we cannot get as far as u-boot on these boards!

Many thanks,

Tom

Please check the following page: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1358039/faq-board-bring-up-tips-for-sitara-devices-am64x-am243x-am62x-am62l-am62ax-am62d-q1-am62px

section "Running memtester (DDR memory test) from R5", this provides a patch that will run memtester immediately after DDR is initialized.

But before you do that, have you used the DDR register config tool https://dev.ti.com/sysconfig/?product=Processor_DDR_Config&device=AM62x to configure the DDR for your board? If you are using the default configuration from the SDK, you may need some tweaks to the configuration depending on the type of memory you are using or your board design (eg, configurations like drive strength and termination may need to be adjusted)

REgards,
