PIC32MZ Starter Kit - pure microMIPS port query

Posted by binarymage on July 14, 2014


I've recently completed a port of the kernel and demo for a pure microMIPS build on the PIC32MZ Starter Kit (a PIC32MZ2048ECH144 part), and I have some patches that I'd like to submit to enable the demo to work correctly in microMIPS only mode; what would be the best way to submit them (once they've been cleaned up a little) so that they can be incorporated into a future FreeRTOS release? Should I post them here for review, or is there somebody to whom I can send the patches?

A quick summary of what's been done:

  • various assembly files have '.set micromips' inserted into them (both in the demo and the portable kernel source);
  • the branches with absolute addresses in 'RegisterTestTasks.S' in the demo have been changed to use forward assembly labels (i.e. "beq $22, $0, .+16" -> "beq $22, $0, 0f").

Thanks, George

Hi George - thank you for your contribution. Normally I would ask that you post the changed to the FreeRTOS Interactive site - which I would still encourage you to do - but I would be grateful if you could also email the whole buildable project (preferably without any absolute file paths) to the "Business Contact" email address on http://www.FreeRTOS.org/contact
