Build Failed with PIC32

Hi,

Could anyone explain why my project failed to build. The compiler error message is listed below.

Particularly things such as “undefined reference to `vPortStartFirstTask’”

Nothing regarding the compiler has changed.

I am using the PIC32 compiler from MPLab

This project is a copy of the PIC32 demo project that comes with FreeRTOS

I can upload the project if someone tells me where.

Many thanks
Grant Brown

The functions it cannot find are all defined in FreeRTOS\Source\portable\MPLAB\PIC32MX\port_asm.S - so I would guess this file is not included in your project.

I have just noticed that there is a new version of MPLAB available.  Maybe this is why there have been a couple of PIC32 build problems in the last couple of days.  I’m just downloading it now to see what effects it has on my build.

I just tried with MPLAB V8.15 and a clean install of FreeRTOS.org V5.1.0 - all built with no problems.

MPLAB now contains a FreeRTOS viewer.

Regards.
