AM62L-PROCESSOR-SDK: tispl.bin doesn't work on the custom board.

Hi TO,

TO said:

1.Does tispl.bin work on DDR?

Yes, the TF-A provided in SDK 11.0.15.5 should have DDR4 support.

Yes, tispl.bin runs on DDR. If DDR is not configured properly, likely tispl.bin won't print any message on the console.

TO said:

3.If I change the DDR from EVM, I think I need to readjust the DDR parameters. Should I use the .dtsi file output by sysconfig with TF-A?

Yes, you should use SysConfig tool to generate the new DDR config data and integrate it to TF-A.

Hi Bin,

Thank you for your support.

The DDR parameters have been adjusted and integrated into TF-A.
However, the console stopped at BL1 and could not proceed to BL31.

The console log is as follows:
Checking the log shows "bl1_platform_setup DDR init done" is output.
Does this mean that the DDR parameters are correct?
If the DDR parameters are incorrect and BL31 does not boot, how should I handle this?

The message only tells the DDR init is done, but it doesn't mean the DDR Config parameters are correct.

I am routing your thread to our DDR expert for comments.

The message means that the training completed, but it doesn't necessarily mean it completed successfully.

Can you send the DDR part number and/or datasheet, along with the changes you made from the tool (.syscfg file)

Regards,

James
