Hi,

Thanks for putting out this FreeRTOS C28x port!

I'd like to add the below F28027 example which runs on the TI Launchpad. TI LaunchPad is pretty popular so this might increase usage of your port.

blinky_tms320f28027.zip

Or could you add this new example yourself?

Thanks,

Entering into critical section shouldn't disable all interrupts globally. Instead, user should be able to configure which interrupt groups are under RTOS control and only these groups should be disabled.
Something similar is implemented for other ports by configMAX_SYSCALL_INTERRUPT_PRIORITY.

Your README states that the repo is licensed under the "FreeRTOS Open Source License", but the link provided now points to the updated license for FreeRTOS, which is MIT, while the license header in the source code still refers to the old license, which is GPL with a static linking exception. At the moment it would still seem this is the license the project uses, but it would be good to either update the license to reflect the FreeRTOS MIT license (if you're willing to do so), or include the full text of the old FreeRTOS in the repo, to make the licensing situation clearer.

FreeRTOS/portable/CCS/c28x/porASM.asm:

; Save stack pointer in the task control block.
MOVL XAR0, #_pxCurrentTCB
MOVL XAR0, *XAR0
MOV AR6, @sp
MOVL *XAR0, XAR6

The value of the SP is copied to the low word of XAR6, AR6, and the high word of the XAR6 isn't modified. It makes the pxTopOfStack point to an adress ot of stack area of the stack's current task, resulting in data corruption and stack overflow. XAR6 must be initialized before:

; Save stack pointer in the task control block.
MOVL XAR0, #_pxCurrentTCB
MOVL XAR0, *XAR0
MOVL XAR6, #0 ;set to 0 XAR6 before move the new value of pxTopOfStack
MOV AR6, @sp
MOVL *XAR0, XAR6

Check if cooperative mode is working.
If not, fix it.

Ivan, I posted this on the FreeRTOS interactive site:

Hello Ivan,
Thanks for sharing your port. I had worked on this also some time ago; but not quite completed; I did get a 'blinky' port working for the 'c55x series.
I modified your port to run on my 'Themis' target - TMS320F28069 target - and it's running fine. I will let you know if I run into any issues.
I currently have red and green leds blinking.
Thanks Again,
John W.

Wanted to say thanks!
