Error "Illegal priority call to llEnter()" source is priority setting

Raymond Mack

Can we capture this on E2E? I looked at the only other thread regarding a C2XXX part issue and it really doesn't answer this question.

I finally read the llEnter section (5.2.3) in SPRU523 and it explains the main problem. We were using the SYS/BIOS Task_create() call rather than the NDK task creation call. We were also using a higher priority (12) than the max NDK priority (10) which is documented as a defective way to design your code.

Time to read that section in real detail!!

I have put in a Document Change observation for SPRUEX3 and SPRUHD4 to have the writers add notes to point to the need to use the NDK interfaces is using the NDK.

Just to make sure...you're not looking for an answer here. You just want to make sure that people avoid the issue you hit...correct? If so, can you mark your post as an answer.

Thanks,
Todd

Yes, this is an answer rather than a question. I looked here first and did not see a pointer to the correct place which is way at the end of the manual. Also, the manual early on has an example of using the SYS/BIOS call rather than the NDK call, so other users might be confused when trying to find the answer. The correct answer is in section 5.2.3 (which coincidentally is the number of the document!)

Fair point. I opened an enhancement request for the document.
