  1. i'm designing an embedded control system that i've prototyped with the TM4C123GXL Launchpad. i like the processor (TM4C123GH6PM) and need the speed. i'm experienced with code, hardware, board layout, etc. my question seems to be somewhat between a TI/hardware issue and an Energia software issue. for various reasons (including a desire to let eventual end-users write code for it) i want to use the Energia IDE with boards of my own design, that use only native USB, and not the secondary debug processor. the bootstrap process remains fairly opaque; i've read the datasheet and ROM app note etc but i seem to be missing something... ** is there a usable Energia-compatible bootstrap routine, compatible with Energia, in the ROM on TM4C123* chips i buy from Digikey? ** if not, can i use an external method to load bootstrap onto the board, that will persist, ala Arduino? i've read that there are licensing problems with the TI USB libraries; are those entangled here? tom
  2. hi, newbie to the forum, but experienced programmer/electronics geek and a couple years experience with the TM4C123GXL Launchpad and Energia. i'm now prototyping a project using the Launchpad but will want to layout a PCB with the TM4C123AH6PM chip on my own board. i'd like to continue using Energia for development, so that end-users of the thing can get at it's innards. what are my options for Energia-compatible bootloaders in the embedded, non-Launchpad case? (the Launchpad has a second TM4C123 to handle the debug USB port.) i realize i'll give up some of the debugging features but that's acceptable.
