Hi,

I have not found anything that could explain the error, but I notice you have changed the ID numbers you stored to the ucProcessChar[] array, which makes it more challenging to figure out what the original execution sequence was. I also noticed you have reverted back to using zero latency interrupts again. This is not recommended.

Could you try to use SEGGER SystemView as described in the link below to see whether the alg_thread is running after the UART event or not?
