AM2434: Debug Configuration Boot Error only on some hardware

Marshall Folkman

Part Number: AM2434

Support,

I have this weird issue where my debug configuration works on my AM2434 Launchpad, but will not work on two other launchpad boards. The other two boards were previously running another project and I'm out of the loop on it's history, but I'm told that they never had this problem. This doesn't make any sense to me because the bootloader should be performing a mass erase on the boards so it should be hardware independent. Note that my project is running all four R5 cores and both PRU_0 and PRU_1.

The issue is that when the debug session gets to the PRU_0 core, I get a brief "WAITINGTOCONNECT" status before the session ends unexpectedly. Then, looking at the debug output I get this error in the logs:

"ICSS_G0_PRU_0: GEL: Target must be connected before calling the function."

What could be causing this to happen on the other two launchpad boards and not my launchpad board?

Here is a video of the behavior I’m seeing on the other two launchpad boards as described above.

Hi Marshall,

Please tell which version of SDK are you using?

Which example are you trying to run?

Also please share screen record of the example loading and failing case for analysis.

Regards,

Tushar

I'm using MCU+SDK AM243x version 10.1.0.32.

I believe this project was based on empty project examples. I did copy-paste some things over from one of the DMA project examples.

I already shared a link to a video that shows it failing on the other two launchpad boards. Here is a video of the exact same project being executed on my lauchpad board, which works as expected:

Instead of doing direct project debug from CCS, can you try once with the project-less debug method?

Please refer CCS_LAUNCH_PAGE for details.

Please let us know the results.

This worked by following those steps to switch my boot mode from QSPI to UART, then opening a terminal within CCS, navigating to here:

  cd ${SDK_INSTALL_PATH}/tools/boot

And then running this command:

  python uart_uniflash.py -p COM<x> --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg

Then, I powered off the board, switched the boot mode back to QSPI.

After doing this, I am now able to run my project on the device that was not working.

Thanks for the above confirmation.

Glad to see you are now able to debug.
