RTOS/AM5728: IPU0 app crashes with code in OCMC RAM

Pavel Azizov42

Part Number: AM5728

Tool/software: TI-RTOS

Hello

We have encountered the following issue.
We load applications using with MLO-app.
When we move IPU0 code section from DDR to L3 (banks OCMC_RAM2, OCMC_RAM3)
application crashes while Program Counter pointing to some meaningless location in DDR.

We use TI RTOS SDK 03.03.00.04

Thanks

Pavel,

The MLO on AM572x does not support DDR-less mode, see processors.wiki.ti.com/.../Processor_SDK_RTOS_BOOT_AM57x :
- Parses Multicore Application image located in memory device and copies it to DDR memory based on load address for different sections.
- Once copy is successful it transfers control to application.
- Application then starts executing from DDR.

Regards,
Garrett
