Hi Beginner in rust here, I just finished The Book, and am starting my journey In embedded rust with the pico-2 using the rp235x-hal.

However I have hit a problem in my project where the uart doesn't seem to work in rust, whereas the exact same pins work when using c.

for reference my pico 2 is not the A4 stepping so it has the chip erratums(could this be the issue).

and my project uses the tmc2209-uart crate.

for some reason even though I write to uart there is no echo coming back. kindly advise.
