TMS570LC4357: TMS570LC4357: CAN Bootloader flashing FreeRTOS

Hi Aman,

RTOS supports two type of tasks: privileged task and unprivileged tasks. A privileged task has access to the entire memory map, but an unprivileged task only has access to its stack. A task that is running in unprivileged mode cannot set itself into privileged mode.

Does your task access a MPU protected region? Can you try the same operations in a privileged task?

I am not familiar with safeRTOS.

Hi QJ,

Thanks for your reply!!

Could you please check the linker file that I have attached reason being that on debug, got the errERROR_IN_VECTOR_TABLE error of xTaskStartScheduler(). Facing the same with freeRTOS as well. 

Linker cmd looks ok. But the .intvecs only takes 0x20 bytes, please change 

VECTORS (X) : origin=0x00020000 length=0x00000080 vfill = 0xffffffff

to

VECTORS (X) : origin=0x00020000 length=0x00000020 vfill = 0xffffffff

The unused flash doesn't have valid ECC value.

Can you share your section configuration in your application linker cmd file? Are the sections 32 byte aligned? 

Sorry for the delay!!
