Hi everybody! Firstly seeing an SoC vendor reach out directly about enabling their HW in Debian seems great to me!
I have been doing a little bit of this work in the past, asking the Debian developers to add support for certain devices I had been working with. It was a very slow process, often years between me establishing contact and an actual release supporting a device. It turned out that I didn't always have the time to follow through, and also sometimes encountered bugs specific to the more obscure components like debian-installer. I'd like to make progress with this approach again, eventually. Especially with SoC vendors supporting upstream Linux well, such as NXP (which I work with a lot) - but also Renesas (my colleague tells me), support is quite possible. So @Huynh, I'd be happy to assist / answer some questions. However note I am not part of the Debian project. I don't know if joining makes sense, I don't know if the Debian project would like to incorporate some developers who specifically would collaborate to support certain vendors in Debian..... Just - there are things outsiders cannot do - like maintaining a "Blend" e.g. Sincerely Josua Mayer Fabio Fantoni <fantonifa...@tiscali.it> schrieb am Fr., 18.
