@0xc0170 I did look and couldn't see anything obviously of interest in STM32L1 between releases. I suspect it may not be L1 specific, If i have time tomorrow I will try a different target.

My mistake...

Issue is known and corrected since #14032

chrissnow commented 3 years ago

@0xc0170 Apologies for the delay, I was away on site late last week.

I haven't tested the change above, but the changes in #14337 wont build for me (comments left).
