This patch supports new platforms available under same TivaWare umbrella, enhances portability and correct architectural deficiencies and inconsistencies in StellarisWare.

More detailed features for further migration can be referenced from: http://www.ti.com/lit/an/spma050a/spma050a.pdf

Tested on Tiva C series TM4C123GH6PM.

Oh very nice! I'll have to try it out on my old tiva boards. I do remember TI renaming everything while I still had my stellaris board.

This looks nice, but there is a built failure or two in there, can you take a look? I have my old Tiva C launchpad ready to test this on.

Yeah, the problem is with the toolchain arm-eabi-7.3.0-Linux-x86_64 I guess, I am using arm-none-eabi-7-2018-q3-update and it works fine! Also check using their respective higher versions available.

driverlib/hibernate.c needs time.h which is not included in the arm-eabi but is available with arm-none-eabi. travis-build only uses arm-eabi and throws error

  1. Removing hibernate.c from MODULE_SRCS works well. So we can push initially without including it in rules.mk You can also test it initially
  2. Both StellarisWare and TivaWare looks for arm-stellaris-eabi if it exists, fallback to arm-none-eabi otherwise. Can we use arm-none-eabi for travis-build as well?
  3. ?
