Thanks for testing all of this.
Unfortunately, it doesn't look like there is a cheap solution for this problem.

Assuming this problem exists in master before the 5.4 bumps as you report, and taking into account the age of the device/target, the fact that it's a single-device target, and the (very low) activity besides my bump, I decided to not invest further time and drop this together with the other 4.14 targets. Sorry.

Best

Adrian
