![]() The new firmware will be loaded into the PIC. Always follow this order or the bootloader may be damaged. Next, click download on the bootloader software within 3.5seconds. Press the reset button on the web platform.Configure the bootloader to communicate with a PIC 33FJ128GP204 at 115200bps on the appropriate serial port for your system.Attach a USB cable from a computer to the web platform.The bootloader passes control to the main firmware if it doesn’t detect an update request after three seconds. It activates immediately after power on and waits for a commands entering the UART connected to the FTDI USB->serial converter. The bootloader resides in the uppermost page of the PIC program memory. The bootloader is programmed into the chip once with a PIC programmer like an ICD or PICKIT, then future updates can be done over the USB port. The ds30 Loader project has serial bootloader firmware for most PICs, and bootloader software for most computer operating systems. We ported the open source ds30 Loader bootloader to the web platform so it can be programmed through the USB connection no PIC programmer required. ![]()
