ARM |  Long ISR crashing RTX? Stefan Hartwig 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. | | Read-Only Author

ARM | RE: But without RTX it does NOT crash... Andy Neil 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...? | | Read-Only Author

ARM | RE: But without RTX it does NOT crash... Stefan Hartwig 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. | |
