  1. 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 memory locations. Also, I specify in ram the exact location of every bit of ram I use, other than the stack of course. It all fits in 1K, but with exactly four bytes to spare. If I do away with setup() and loop(), and just stick with a main(), is it possible to do stuff like this in Energia? Is it possible to specify exactly where things will be located? Are there any examples of doing this kind of conversion? Well, this may be a bridge too far. But I thought I would ask. I was also thinking that if the C++ code worked in Energia, it could possibly be ported back to the Arduino world.

    Bootloader on CC1310

    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!

    MSP430 USB Bootloader

    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
  4. Hii All... I'm new to msp430g2 series MCUs. Is there any UART and USB bootloaders for MSP430G2 series MCUs ??
  5. 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 possible to debug assembler code at this stage (in the reset handler) at all? In the debugger plugin in eclipse I choose to break e.g. in ResetISR, but it stops somewhere else. Can anyone give me a hint what I am doin wrong, how to correctly setup the debugger for this project? Thanks in advance, Andreas
  6. 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?
