I am working on a motor control application. I have the motor control part which I based on lab11 of motorware and a bootloader which I created. The motor control application runs, I have the blinking LED/comms as required, but the motor itself doesn't run properly. When I load the application via the jtag and not my bootloader it works.
I use the following post build step to generate a bin to create the proprietary file from:
"${CCS_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin" "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.bin" "${CG_TOOL_ROOT}/bin/ofd2000" "${CG_TOOL_ROOT}/bin/hex2000" "${CCS_INSTALL_ROOT}/utils/tiobj2bin/mkhex4bin"
However when this runs I get the following error:
warning: section prjlab11-8305.out(.econst) at 07ebe00h falls in unconfigured
So I'm guessing this section is not making it into the bin file which is why the motor won't run properly. To bootloader lives in flash A and the motor control lives in flash BCD. I use a modified cmd when linking, included below. I'm sure I could do things better, but this does (when loaded via jtag) work. Can someone please offer me some advice?
