Hi, may a "long" going interrupt service routine crash the KEIL RTX?
I currently porting a USB-CDC-Firmware to work with RTX and came into trouble, but did not find the problem yet.
But without RTX it does NOT crash...
Possibly, you were just "on the edge" without RTX - and with it, you are (just) over the edge?
Does the RTX documentation state any limits on ISR timings...?
I found the problem(s): - I used os_evt_send instead of isr_evt_send - the task returned because of a break inside the invinite loop
Many thanks for all ideas and hints.
