NFC using app_scheduler.h and freeRTOS not working

If it is a hardfault, you need to debug them as guided in the links. It is hard to guess what the hardfault source is without gettting the hardfaulting instruction. Try to find the exact instruction that is causing the hardfault and you will have better context and understanding on the problem.

Hi Susheel,

No Unfortunately. but it works with this modification, I increased the number of FDS_VIRTUAL_PAGES to 6 pages and for information it works in normal mode but not in debug mode , when I start to write data in NFC tools it generates a hardfault after updating data in flash file (I don't know if it's related to the timing).

Thank you

Thanks for link Loura, does the solution in the other thread help you in this case?

Hi Susheel,

Thank you for your feedback .

in fact when I debugged the software, it was this ndef_file_update API that gave me a writing problem, it was not even the app_scheduler. once it updates the NDEF message, the software crashes in the SELECT_HIGHEST_PRIORITY_TASK task. Thanks .

Thank you ... again

Lora

Hi,

Unfortunately we do not have any example to show app_scheduler and freertos combined together. The whole point of using an RTOS is to phase out the app_scheduler. I would first strongly recommend you to put some efforts to move app_scheduler logic into a new task in the freertos.

If you are really in a situation where you unnecessarily have to use them together (app_scheduler and freertos) then please give us more information about the hardfault (log) and more context on the fault causing instruction.
