Dug out the Duemillanove and tried MPIDE - did not compile. Tried Energia with the Tiva - did not work. Hmm, must get back to Arduino and stick with it, it seems. Can someone tell me why ? I don't get it.

GNU MCU Eclipse 64-bit Open On-Chip Debugger 0.10.0+dev-00462-gdd1d90111 (-11:42)I don't know what I've done but toolchains like to bite me. “internalConsoleOptions”: “openOnSessionStart” “svdPath”: “C:/Users/xxxx/.platformio/platforms/titiva/misc/svd/lm4f120h5qr.svd”, “toolchainBinDir”: “C:/Users/xxxx/.platformio/packages/toolchain-gccarmnoneeabi/bin”, “executable”: “c:/Users/xxxx/Documents/PlatformIO/Projects/190401-213901-energia-blink/.pioenvs/lplm4f120h5qr/firmware.elf”, I can still upload to ROM but error on debug.

I would much rather use this than Keil if at all possible. I’m able to upload the image to my TI board but not able to do any debugging using JTAG. I’m basically an infant using Platform IO.
