Hotend seems to be running hotter than reported
I've been printing lots of good looking prints of TPU on my V Minion for quite some time. Suddenly, I hear crackling during printing and get very rough looking prints with sagging bridges and rough porous walls. I lower the temp from 240 to 220 and then get decent looking prints again. And yes, I dry my filaments. This issue happened overnight. What's going on?

Terrible under-extrusion with TPU
Stock V Minion: bondtech lgx lite, dragonfly BMO. I can't even extrude more than 50mm before it either clogs or just slows down to a halt, but then if I request another extrusion, it'll squirt out a little bit more. It's not a smooth extrusion, it speeds up and slows down. I'm extruding at 3 mm/s at 240C. I've also put the extruder tension in the flexible setting.

Zero extrusion during print
I am using a stock V minion and stock superslicer profile for the minion. In RatOS, I can command an extrusion which works fine, but nothing comes out when I run a print job.

SKR 2 will not flash firmware
it won't load the firmware from the sd no matter what (formatted to fat32, 4kb cluster, tried multiple sd card sizes (2, 4, 64gb), tried changing file name to various things, tried with USB power and 24v power supply, unplugged everything from it, tried multiple compiles and ensured its for my 429 version, etc). What else can I try?
The way I'm checking if the flash was successful is by seeing if firmware.bin changes to firmware.cur on the SD, which it does not.
