If the bootloader does not work If the bootloader hangs after programming the first block, be sure that you have compiled the bootloader firmware so that it starts at 0x400 and not 0x200 (if it starts at 0x200, it will erase itself). The upper part of the bootloader application window shows what is happening on the serial port, you can use the Send button to send data in the type-in field to your application via the serial port (the Sendn sends the data with a new line).

The bootloader will pulse the MCLR input via RTS or DTR (both are pulsed), and then download the program. If the bootloader is able to establish a connection, you will see your hex file downloaded to the target device.ĭownloading a program via MCLR and Prgrm button: If you have the RTS or DTR line of the USB-to-Serial cable connected to MCLR, then press this button to program.

The project assumes a PIC24HJ32GP202 processor and uses the linker file lkrp24HJ32GP202bootldr.gld file.ĭownloading a program via Power cycle or MCR: Cycle power or assert MCLR to your target PIC24HF when power is applied or reset is released, you have about 2 seconds to press the Program button in the Bootloader window.

Our default test program is the chap8reset.mcp project. The Hex file must be have been compiled using a modified linker file such as those found in lkr. In the bootloader application: Choose the appropriate COM part and baud rate (the default baudrate in the bootloader firmware is 57600, the bootloader firmware does not autobaud).Ĭlick on the port checkbox to open the port Use the HexFile button to browse to a hex file for download.

If you have the RTS line the USB-to-Serial cable connected to MCLR, then the RTS checkbox pulls MCLR low when checked, and MCLR when unchecked. If it does not run then try installing the latest.NET runtime from Microsoft as this is a.NET application.NET Requirements You need at least.NET 2.0.XXX or above runtime framework installed. If you processor is not currently listed, simply use a text editor to add it.

To install copy this.exe and the devices.txt file to some target directory.

Look at the comments inside the linker files as well as the AN1094 application to see the changes from the standard linker files.īe careful when modifying linker files for the PIC24F family you must change both the code origin and length fields (see the sample PIC24F linker file provided and the comments). If you compile to a new target, please be aware that you have to provide a customized linker file for the bootloader so that it starts at location 0xC00, and not the default of 0x200. The current code uses RB10 for RX, RB11 for TX, and the internal oscillator 40 MHZ FCY (PIC24H). You will probably have to modify this source to map the UART TXRX pins to your desired target, as well change to your desired starting baudrate and clock configuration.

The supplied executable has been reported to be incompatible with WinXP64 but recompiling from the source may work (untested, the source files are supplied in the archive).After unpacking, you will have the following directories: bootloaderpic24dspic33bootloader.X - Source and MPLAB project for the PIC24 and dsPIC33 series bootloader firmware code to be loaded on the target processor.
