Hi, is there an ARM 7 compatible implementation available. My MCU is a TI UCD3138, digital power Controller, having a ARM7 core wich runs in 'Thumb' mode. I only Need Semaphors, maybe Queues.

Thanks for helping. With best regards

There are lots of ARM7 ports for various different compilers, but unlike the Cortex-M ports each one is different because each has a different interrupt controller and a different peripheral to generate the tick.

Look in the FreeRTOS/source/portable/[compiler] directory for whichever [compiler] you are using to see the chip specific ports. You can use one of those as a starting point but will have to update the prvSetupTimerInterrupt() function within port.c to use a peripheral available on your chip, and of course handle interrupts in a way that is appropriate for your hardware.
