LP-AM261: I having problems with PRUICSS_loadFirmware()

Tool/software:

Hi!

I have been developing/debugging an application on the PRU the following way:.

1 Load my FreeRTOS application on R5_0 via jtag

2 Halted R5_0 at AppMain() in freertos_main()

3 Attached to ICSSM1_PRU_1 and loaded my pru.out application via CCS

And that has worked fine for me, but now I need to switch over to loading the PRU application programmatically via PRUICSS_loadFirmware() and I just can't get it to work.

I have enabled the "PRU hex utility" and the output format is Array (--array) but maybe there are some other settings that I need to configure? And is it possible to step trough the code when you load it with PRUICSS_loadFirmware just like when you load the application manually via CCS?

Best regards

Daniel

Hi Daniel,

I was able to try it today, and I see that I am able to the code and debug through it. Could you let me know what challenge exactly are you facing.

Yes it is possible, you will need to put a forever loop in the beginning and then once the loading is complete , you need to remove the loop then continue to debug further.

This is needed because when R5F loads it debugger is not able to halt the core automatically.
