Hi All,
I am hoping to use GCC to compile code for the TMS570LS3137 or TMS570LS43x processor which are big endian Cortex-R4 and Cortex-R5F respectively.
I have found some old instructions here: TMS570LS and GCC compiler - Hercules safety microcontrollers forum - Hercules ︎ safety microcontrollers - TI E2E support forums. I will attempt to follow them today.
Can anyone provide some explanation of how to build GCC including the libraries for big endian? Is there a recent, pre-build set of tools that support these processors?
Thanks!
Not that I am aware of, if you just require a cross build you have two options:
Use a tool such as https://github.com/crosstool-ng/crosstool-ng which allows you to generate a compiler for a specific target.
You can then just create a big endian target using this. Otherwise you could download the source for the GNU releases and modify the multilibs list to include a big endian multilib.
