Having issues getting the firmware on Teensy #94

Closed salsa33 closed 3 years ago

salsa33 commented 3 years ago

When I try to load the firmware on the teensy board through teensy.exe it says the hex file is too large. Verbose info says “file contains data beyond chip size.” I inherited this task of assembling the thermocam from someone else, so I’m unsure if the purchased pieces separately or the kit online. Any info would be appreciated!

Tried getting the firmware onto the Teensy by using VSCode, but now I'm getting errors with MTP even after unzipping the updated info to the correct folder.

Hey @salsa33,

did you assemble the DIY-Thermocam V2 or V3?

Try to flash this hex file first: https://github.com/maxritter/DIY-Thermocam/blob/4b86ec988f69ddeae3e1c9218e800dde4bc6906f/Software/Firmware%20Updater/Teensy%20Loader/FileTooBig.hex, then try again the compiled firmware version. Make sure that if you have a V2 device, only flash firmware version starting with 2.x.

Hope that helps!

The board has V3 printed on it. I'm not the one who built the kit, I just inherited the issue XD. I'll try this hex file and see what happens. I'll be working on it later today anyways. Thanks for the response!

Works now, I didn't even need the other hex file, this time when I opened teensy.exe it loaded just fine. Either way, thanks for responding.
