Hello yocto friends, I have a problem with yocto you could help me with. The Background: Iam working on a yocto-linux for a TI OMAP-L138, which is a ARM9+DSP in one package. The Linux on ARM is running fine, and does everything I want. I have implemented a kernel driver to start the DSP-Core from the Linux on the ARM9-Core, but now I need to generate the Firmware for the DSP with the Yocto buid system. Main problem is, that I need a compiler/toolchain from TI to compile the Code for the DSP in the yocto build environment.
At this point I did not understand how to add tools to the yocto build environment at all. I think there must be a way to add software to my host (build) system for generating code for my target. But I have no idea how to do it. When I write a BB-recipe, the architecture of the resulting files is checked to be from targets type (arm in my case), but host tools are of type x86... (which is totally correct!) I think I need a recipe, which downloads the compiler/toolchain for the DSP, extracts and installs it to my yocto build environment, so that I can use it in another recipe that compiles my code to a loadable firmware-image (which is placed to my targets rootfs). Do you have any suggestions for me how to do that? Thanks, Lukas
