Hi guys, I have a board which has both a Cortex-A9 and a Cortex-m0+, The Cortex-A9 is running the main application with the Linux kernel while the cortex-m0+ is present to handle some real-time control tasks.
Currently, I am building the cortex-m0+ firmware separately and saving the artifacts to an ftp server. A bb recipe grabs the correct binary from the server and incorporates it into the rootfs of the cortex-a9 image. This works for now, however it makes it a bit more difficult to do development on the cortex-m0+ firmware. I am looking at augmenting the recipe so that it will pull the source and build the firmware. The complication is that since it is a completely different architecture, I will need to use a different toolchain, CFLAGS and complier options. I am not even sure if this is possible or where to start. Anyone have any ideas? Thanks Logan
