Bootloader Update

The USB-based bootloader in UPHCC-usb usually does not require updates. However, if you built a UPHCC-usb board yourself, you need to program the PIC microcontroller with the bootloader to be able to upload firmware into the PIC via USB. Below are the steps required to perform this bootloader update.

What you need

• Hexfile of bootloader:
• ICSP-capable PIC Programmer
  • cable to connect programmer to UPHCC-usb board with correct pinout
• Programming software
  • for Windows: Microchips
  • for Linux: fsusb

Connecting the UPHCC-usb to a PIC programmer:
