Hello,
I use the TMCL-6110-TMCM board and had one experience a catastrophic failure with part of the microcontroller blowing off. The board still worked slightly; the I/O didn't work, but the green LED still blinked, and motors turned. I could just buy a new board, but I wanted to challenge myself to change the microcontroller. A new microcontroller was acquired and mounted successfully, but when I plug the board into the USB port, there's no indication from my PC that anything is connected. Also, the green LED isn't blinking--neither is the red one; both are extinguished, but do work. These two things point to the microcontroller needing to be programmed through four test points on the bottom of the board. Is that correct? And do I just upload the standard Trinamic firmware? Or is there a bootloader that should be programmed? Can I use a generic SPI hardware programmer? And which software to use to upload the firmware?
