It's been sat there "thinking" for several minutes now!

Just putting "NUCLEO-G474RE VCP" did get an answer

Hi @Andrew Neil,

Thanks for letting us know. I just have tried to replicate, and I got the answer rather fast with your orginal imput. Perhaps it's a network issue. Can you please try again and see if it happens again?

Thanks,
Lina

But the answer is incorrect:

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

I tried again with the original question, "What UART is connected to the STLink VCP on NUCLEO-G474RE?", and did get the answer within its usual "thinking" time this time

And, this time, it did give the correct answer!

Dear @Andrew Neil @Lina_DABASINSKAITE ,

Thank you for the feedback, much appreciated. We fully analyzed the case, and here are our comments:

15 minutes waiting is not normal and is not related to STM32 Sidekick, but we got at that time a global platform glitch and all contents view disappeared on ST Community. it is fixed now.
UART2 or UART1, indeed the sources reference of the answer was using a generic document that need to be updated AN4989 page 69. we will use it to improve our documentation with different variants of MCUs.

Thanks again and wish you a great day,

STOne-32.

So it is:

But interesting that it managed to get the correct answer with the long-form question!

PS:

But, as @waclawek.jan says, UART2 is also available on PA2 & PA3 - see:
