Hi Caihang,
Technically it is possible to run Ubuntu on S32V234. But currently we do not provide any support for it.
Moreover, we have stopped supporting this community group. But we still support S32V2 question using our ticketing system.
For future questions, please create the request at www.nxp.com/support using Support Requests option. Our experts will help you.
Thank you for understanding.
Regards,
Kushal
