Hi, I was testing eCos together with Cyrill. Basically there is no application
programmed by us. We just used the timer test in the cortex stm32 HAL section.
We configured two timers and added some code to toggle hardware pins
(oscilloscope). To force the error within a couple of seconds we changed the
idle thread from WFI to a NOP instruction.
It should be easy to reproduce the error just by running some timers and set
the idle task to NOP instruction.
