Other Parts Discussed in Thread: EK-TM4C123GXL
Hello,
I am working with our software engineer and we are running into an issue attempting to port a project from the LM4F211H5QR to its replacement the TM4C123AH6PM. We have our original code written for the LM4F211H5QR and compiled and functioning through Code Composer Studio (CCS) versions 5.5 and 6.2 on the TM4C123AH6PM microcontroller. Both of these versions of CCS have a selection for the LM4F211H5QR variant with the M4 core and this works for us when compiling and loading the firmware to the TM4C123AH6PM we use now. We are now trying to run the same code in CCS 12.3, version 12.3.0.00005. This newer version, however, does not allow us to select the old variant and core and only has an option for the TM4C123AH6PM variant with the M4 core. When we use this variant, the code no longer functions properly and flags error regarding ROM definitions.
When attempting to compile, some of the #Defines in the rom.h file are not recognized and our software engineer has been having to port the new definitions from some TI examples to our existing code to try to get it working. Some defines in our existing rom.h file, for example, have different names than the example rom.h file, for example this one.
Others, such as this one, don't exist in the example rom.h file at all.
Our code was originally designed for the LM4F211H5QR, but the TM4C123 is supposed to be identical. If we are using the older versions of CCS this seems to be the case when we select the LM4F211H5QR variant with the M4 core. However, this option is no longer available in CCS 12.3. We expected that selecting the TM4C123AH6PM variant with the M4 core would provide equivalent results, but it is not. Is there perhaps a rom.h file available that we can port in to correctly define everything in the manner the TM4C123AH6PM is expecting in CCS 12.3? Or is there not an easy solution for this?
Thanks for your help with this.
Best,
Noah
