CCS/TMDSEVM572X: Problem with executing NIMU_BasicExample_evmAM572x_arm

Hello,

We have an evm572x board. We prepared example project using script from SDK, and trying to run NIMU_BasicExample_evmAM572x_arm example project.

The problem is that sometimes the program starts and runs successfully, but sometimes (very often) not - it starts from main(), but when we press F8 button, something fails and we get some of the following errors:

NIMU_BasicExample_evmAM572x_armExampleproject.zip

Please help to reach stable results.

Are you resetting the board between runs?

The SYS/BIOS start-up code for a Cortex-A15 attempts to invalidate the cache. However, on the Cortex-A15 the cache invalidate instruction actually performs a cache clean which can corrupt the downloaded program if there is any data in the cache from a previous run.

Hi.

Are you resetting the board between runs?

I tried to use only "CPU Reset" feature.

I have tried your "reload" procedure, but with no success. Modified "gpevm_am572x.gel" attached here.

Also I have attached video with the full process: connect to board, execute script, reload program, CPU reset, reload program - the error occurred in a few seconds after execution was paused at "main()". drive.google.com/.../view

Is it really no other ways for coding, uploading and executing (even without debugging) program faster than doing board reset every time? It takes so long every time to reconnect debugger to "A15_0"... Maybe it is possible to do from other IDE, or from command line?
