STM32: Interrupts with higher priority that DON'T call any FreeRTOS API get stuck somewhere

[hs2 (Hartmut Schaefer)]

xTaskCreate(Usart2TxDeferred, "Usart2Tx", 128, NULL,
              configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY,
              &xTaskUsart2TxDeferred);

Note that (hardware) interrupt priorities have nothing to do with / are not directly related to (logical) task priorities.

Yes! That is crystal clear

You may want to query the forum for priority inheritance,

Thanks for the tip!
In-fact I found lots of information (sometimes with very tough examples) with that query
