Hi Lukas, I just installed Ubuntu 21.04 and followed the README.txt and duplicated your issue:

Note it still referenced in their documentation: https://raspberrypi.github.io/pico-sdk-doxygen/pico_8h_source.html I suggest you to return to the older version until we understand how the new SDK work and modify NuttX to adapt to it. I fixed is here this way: $ cd /opt/rasp_pico/pico-sdk $ git reset --hard 26653ea81e340 BR, Alan On 11/20/21, Lukáš Málek <malek.l...@gmail.com> wrote: > Dear Sir/Madam, > > I have been struggling for more than three days with building nuttx for > Raspberry Pi Pico.
