Hi, this is not related to this repo.
AFAIK, there are two problems UART receives data with DMA and printf via UART over USB, right?
You'd better separately test these issues.
- Increase your DMA buffer to cover your single package, which means increasing the buffer size to 512 or more. Using a debugger to see whether it works well.
- For the printf problem, you should check your printf statement first, then try a smaller buffer, if it still does not work, ask the pico community may be a good choice.
