RM48L540: Prefetch entry with FreeRTOS

Leandro Gagliardi

Part Number: RM48L540

Hello,

I am an issue trying to run the operative system over the RM48L540. This problem starts when I create the queues or tasks. At these moment the program finishes in a prefetch entry into the sys_intvecs.asm. I attach some captures below.

Then I tried the same running the example code of RM48 (example_freeRTOSBlinky.c) using the same configuration.

I have to add that I configured the chip using the HAL Code generator for RM48L950ZWT_FREERTOS and I imported the .dil file of TMS570LS3137ZWT_FREERTOS.

Thank you in advance.

Regards,

Leandro

Hello Jagadish,

Thanks! Today I will try to configure the RM48 by copying the same configurations than the TMS570 project (without importing the .dil file of TMS570).

Regards,

Leandro

Hello Jagadish,

I tried yesterday setting the RM48 configurations as the TMS570. The code could create the queues, but not all the tasks. Then, we extended the "Total Heap Size" equal to 16384 in the HAL.

After it, the program run without problems. So, we think that the main issue was the reserved heap.

Thanks a lot.

Regards,

Leandro
