Clean and disable caches before jumping to application. Without this, stale cache data causes the app to crash when TinyUF2 runs at full speed (996MHz) after booting from flash. This matches the approach used in the STM32H7 port.

There was a problem hiding this comment.
perfect, thank you. I would love to have bootloader to run at full speed as well instead of just 24Mhz i.e same clock as applicaton generated with the config tool with .mex file as other rt10xx.
Of course, that can be done with separated PR whenever you manage the time to make one.

Description of Change
Clean and disable caches before jumping to application. Without this, stale cache data causes the app to crash when TinyUF2 runs at full speed (996MHz) after booting from flash.
This looks to match the approach used in the STM32H7 port.
See #466 and #469 where this was raised.
