Could you test locally using NXTMPDIR?

  # NXTMPDIR contains a cached version of the esp-hal-3rdparty repository, which
  # is located on nuttx/../nxtmpdir/esp-hal-3rdparty if it exists.

@simbit18 Aha this is very interesting. Does it mean I need to delete nuttx/../nxtmpdir/esp-hal-3rdparty, while Retrying CI Builds, in case it contains Corrupted Downloads?

• CI: Remove corrupted downloads for build retry #18763

[simbit18]

Hi @lupyuen, yes, that would probably be best, just to be on the safe side.

At the moment, the esp-hal-3rdparty repository is cloned just once and used for the Make build of all Espressif boards. So, of course, there is a chance that Git might not work properly.

[simbit18]

Hi @lupyuen @fdcavalcanti @xiaoxiang781216

This PR looks fine now :)

I've also added a function to remove the folder nxtmpdir if the NXTMPDIR variable isn't set to ON
