Dear all

I downloaded the 'PIC32-avrdude-bootloader-master' and open the example bootloaders in MPLAB. Of all the projects, only one can successfully be built.

Only ' Uno32' can be successfully built.

I built ' MX4-USB', error is as follows:

Executing: "C:\Program Files\Microchip\mplabc32\v2.02\bin\pic32-gcc.exe" -nostartfiles -mprocessor=32MX460F512L "main.o" "crt0.o" "cdcacm.o" "usb.o" -o"MX4-USB.elf" -Os -nostdlib -mips16 -mno-float -Wl,-L"C:\Program Files (x86)\Microchip\MPLAB C32 Suite\lib",-L"C:\Program Files (x86)\Microchip\MPLAB C32 Suite\pic32mx\lib",--script="MX3-7-boot-linkerscript.ld",--defsym=__MPLAB_BUILD=1,-Map="" [color=#FF0000]cdcacm.o: Link Error: Could not allocate section .text, size = 594 PC units, attributes = code cdcacm.o: Link Error: Could not allocate section .text, size = 594 PC units, attributes = code [/color] Link Error: Could not allocate program memory collect2: ld returned 1 exit status Link step failed.


Any ideas? Thanks a lot.

Unfortunately, you need the full paid for version of the compiler to build the bootloaders as we have them set up right now. That was the only way that we could make them fit. The full version of the compilers allows for an optimization level of -Os which gives the smallest size. I'm pretty sure that's why you're seeing the problem you are.

You can, however, use the 'split' bootloader, where part of it resides in the 12K boot flash and the rest lives in the main flash with the free compiler. But you'll have to arrange the projects and code a bit yourself to create a version of the bootloader for the specific board you have.

Well, there is a way to turn the free version of MPLAB XC32 into a PRO version with full optimizations. You can make this change anytime (not just during installation) by going to this web page:

Once you make this change, you'll have 60 days to use the PRO version. After that, it reverts to a free version. You can only do this once, so its best to wait until you really need it.

Hope this helps,

can any one help me build my project. I can send you the whole project. Then I can use the built project to program my device.

If yes, please Pm me. thanks a lot.

I use MPLAB X to build my project.

When I use the XC32 as compiler, I can successfully compile. But the programed device is wrong.

When I use the C32 2.02 compiler, I still get the same error.

Where could I get the full version of C32 2.02. Has the bootloader to be compiled with C32?

thanks alot

I've always compiled the bootloader with C32 v2.02. That's what the code and projects are set up for. I'm not sure if Guy's suggestion helps you unless you want to debug what's wrong when using XC32.

I'm happy to try and compile your project for you. Just PM me a link to your files and I'll get HEX file back to you.
