All of a sudden the "Find Usage" feature in MPLAB X stopped working for me. This is strange for several reasons:

  1. It worked on the project I'm working on until my computer restarted (only event I can recall that may have cause a change)
  2. It works in some other projects (but not all), and I can't figure out why it doesn't work in the project that I want.

The project was originally an MPLAB 8 project that was converted to MPLAB X, and like I said, that feature worked and I can't think of any environment changes that potentially caused it to stop working (other than a computer restart).

Any idea where to look, what options to change, or any other suggestions to get that feature back? I find it very helpful, so I'd like to get it back somehow.

Thanks!

  • Close MPLAB X.

  • Make sure it is completely finished (check by using task manager).

  • Go to %localappdata%\mplab_ide\Cache\dev\v3.20 (or the respective version).

    For example this path might be: 

    C:\Users\YOURUSERNAME\AppData\Local\mplab_ide\Cache\dev\v3.20

  • Delete the var folder (make a backup or just do a rename if you are unsure about the consequences).

  • Restart MPLAB X.

  • To confirm that this worked for me using version 5.45 of MPLAB-X. I renamed the directory out of an excess of caution. – uɐɪ Jan 28 '21 at 11:01
  • @everybody: Just to confirm that it also worked for me, Mplab v5.45. Great suggestion/solution user7009351: easy, fast, efficacious. Would give you 1000 points! (and much better than long complex advises found on Microchip forum...) – Guille Feb 07 '22 at 11:20
