  1. We have used Energia for TM4C123GXL for firmware development of a product. Now we want to do firmware updates in the field over USB-serial bridge to UART0. We have successfully used the serial variant of the TM4C123GXL built-in ROM bootloader with Code Composer - built apps to test the serial update process. However with the Energia-generated .bin files, the serial load works but the app does not restart correctly after the load, and requires a hard reset or power cycle to boot correctly. So I think it may have something to do with jumping to the start address after load. I have look
  2. I just posted a Github repo on a 1K SD card bootloader for the G2553 and G2452: https://github.com/gbhug5a/SD-Card-Bootloader-for-MSP430 It's written in assembler, but that's not really accessible to most people who use Energia. So I wondered if it would be possible to rewrite it in C++. But I don't understand much about how C++ does things, and don't know if it's possible to do the same things in the same space, or anywhere near the same space. My code uses all 12 general purpose registers, mainly because operations on registers are smaller instructions than operations on me
  3. I come from programming ATmel chips and trying to understand CC1310 and have some questions, I hope someone can answer them Does CC1310 Launchpad comes with bootloader on the chip? When I upload program from Energia IDE to CC1310 LP, does it upload it directly to CC1310 IC (via serial?) or does it use XDS110 JTAG to program it? Is there a way to use Energia IDE to burn bootloader on external CC1310 (via Launchpad's XDS110) Thanks a lot in advance!
  4. Hello, in my project I want to use the MSP430G2553 as a master which communicates with another device via USCI_A0 UART mode. Is it possible to program the MSP430G2553 via the other modes, e.g. USCI_B0 SPI or USCI_B0 I2C respectively, without the use of a programmer? Are there any tutorials regarding on how to write a bootloader for the MSP430? Cheers, Tim Torpedo
  5. Hii All... I'm new to msp430g2 series MCUs. Is there any UART and USB bootloaders for MSP430G2 series MCUs ??
  6. Hi all, I am trying to debug the bootloader example in eclipse with the jlink debugger. And I am not sure about how to configure the jlink plugin in eclipse correctly, where to point the stack and the pc register due to the fact that the gcc linker script uses the VMA and the LMA for the sections and the bootcode is copied into RAM in the reset handler. The download seems to work correctly, but breakpoints are not reached correctly. I would like to start debugging at the beginning in the assembler code, to see the first steps of copying the bootloader code into RAM. Is it pos
  7. Hello, i bought my msp430 about 6~ months ago, i bought it because i liked the price 4.30$ is really good for a dev board, and now im looking at arduinos, of course i dont want to spent 25-30$ on a board and have been reading about buying just the chip and some other components , slap it on a breadboard and using it that way but the problem is that the atmega328 and pretty much any chip needs to be burned with a bootloader, i read that it could be done from another arduino, but can i do it from an msp430?
