To fit the bootloader into the bootblock, we can stirp unnecessary functions from the source code, like code micrkchip showing the status of the bootloader via 4 different LEDs. If you use the free version of the C18 compiler, the linker will fail since the generated code exceeds the boot block size. See the steps shown below. Digging around the internet did not solve my problem, but it did give me the right hints to find the solution and it’s actually quite simple.
So check your circuit and cable when this error occurs! The bootloader firmware incl. Now you can build the project via “Project – Build All”.

Please make sure that the bootloader entry condition e. I had no problems in writing data to the USB device, mchpuzb after reading data, the USB connection was halted after about 30 seconds. This area is usually used by the application software itself. Further, a linker script is required to make the application software start at 0x The tool itself is selfexplaining.

I have also put a copy of the application onto my webspace, so if the above link is not working, you can get the bootloader PC Software here. All form fields are required. How to compile the USB-Bootloader from Microchip Since the bootloader is designed for the Microchip demo board, the configuration of the bootloader possibly will not fit for your project.
The bootloader checks if pin RB4 is low or high: Select “install from disk” and browse to the following location: Choose the option “select manually Application Software for usage of the Bootloader Programs which shall be flashed with the bootloader need to be adapted since the bootloader uses the memory area 0x to 0x7FF.
You can get it here: After changing the capacitors near the crystal to a lower value, I reinstalled the driver: In the project file the path settings point to the default C18 compiler directory c:
