If there is already a thread on this let me know.
I have a customer request to have the ability to upgrade my firmware in the field. We have nearly 100 machines in the field with many more planned in the next 18 months. I looked around the forum for anything for firmware download besides the USB connection I use for development because my customers want something simple from their side. Primary communications is RS485/Modbus RTU. I expect I will need some kind of Reset system (to get into program mode)
I am using the Teensy 4.1 in C with MS Visual Studio and Visual Micro plugin, is there a way already in the boot loader or libraries available to upgrade my firmware application from the SD card slot (or??) with a HEX file?
Any suggestions would be a great help.
Thanks
