We have a project which is uses some kind of cortex-m0 microcontroller. As i understand it's armv6-m family. Is this CPU family is supported by rtems? I'm reading the book called BSP and device driver development guide and it says look at cpukit/score/cpu/CPU. This directory contains only armv7-m and armv4 files. Is it correct? The armv7-m support will probably work also for a Cortex-M0. I think that M3 context switch would be mostly OK. Exception and interrupts model is the same as for M3, but I have feeling that there exists option to use some simplified one - but it can be for M1. But you need to use M0 specific GCC options. We use GCC for nRF51 Cortex-M0 with next options arm-none-eabi-gcc -mcpu=cortex-m0 -mthumb --std=gnu99 -Wall -mfloat-abi=soft Else GCC can use Thumb2 instructions which are not supporeted by ARMv6-m. For example Thumb instructions CBZ, CBNZ, IT emitted by GCC for M3 are not supported by M0. So toolchain rebuild is required for sure.

[PATCH 1/5] capture: Removal of capture task tracking.
This patch removes functionality for stack checking from
the capture engine and requiresi the use of existing rtems
functions for this information. It modifies ctload to use
functionality similar to rtems cpuusage. It removes the
capture task and stores a new capture task record the first
time the task is seen. The per task data that was still
needed is scaled down and stored in the tcb.

If the capture engine is not needed for ctload to work why not move that
code out of here and into the cpuuse command ? It would appear more
available to users.
