FreeRTOS does not execute first task after 'svc 0' call

[hs2 (Hartmut Schaefer)]

That’s what I guessed. And following

@jefftenney

The PendSV handler is intended to be the ISR, not to be called from the ISR. If the PendSV handler is called from the ISR, and if the ISR uses stack, the PendSV handler can’t do its job properly. The proper alternative to opencm3.c is the three #define statements you mentioned earlier that put the FreeRTOS handlers directly into the vector table.

could hopefully solve the problem. @jefftenney is an expert
Are there any hints from the libopencm3 community regarding integration or conflicts with FreeRTOS ?
