Hello,
I'm in the process of making an EV2400 battery tester board. i got the gerbers from TI and build the PCB and ordered the BOM and assembled it.
the problem is now the firmware. initially I thought it would be possible to flash the firmware with USB using BSL but no matter what i do, I can't get it to detect the USB on windows for firmware flashing. in my tests I managed to get it to beep the USB connection somehow by fiddling with the soldering but didn't understand what i did and can't replicate it anymore.
So my thought are that the BSL works and the USB was close to being detected, however due to some HW USB problems, the PC kept losing the USB connection and I couldn't get a stable connection to flash the firmware. I wanted to try using the SBW protocol with the 4 pin header available on the PCB but don't have a MSP flasher yet.
any ideas which part of the build is wrong? AI suggest it could be a crystal problem or CAP problem. i triple checked everything and all seems to be in order.

Hello,
I'm looking for MSP-FET firmware files. does anyone have them? it seems it's possible to extract them from the MSP-FET itself. if that is possible please extract both the main flash and the BSL. The schematics for the MSP-FET Rev 2.5 are available at TI documents and I'm planning to make one. |

I would like to share one of my projects with the sonsivri community.  A game, a simulator, a gift – the development of logical thinking. The game is designed to develop logical thinking in children, and can also be used as a Kit – as a board for learning to program in C and working with microcontrollers from Microchip Corporation. The game can be a gift for a child, for teaching logical thinking, and a gift for a development engineer, electronics engineer, programmer, on the desktop, for a moment of rest and training logical thinking. The game is a touch panel with a light indication of the status and mode of operation. The game can be controlled directly from the panel by touching the touch buttons, or using the computer’s serial port with a simple command system. See the description for setting up and describing control codes. The game has 6 difficulty levels. There are 27 user ratings in each level.
