Alternative use of jetdirect 615n

Question

ARM

I threw out the old coffin clj4550 from the apartment and pulled out the jetdirect 615n board from it.
Having looked in detail, I saw a vt22192 philips chip with a large inscription ARM, a network card, RAM and firmware. I also remembered that with the help of this board it was possible to connect via the web to the printer, download drivers, instructions, and also make settings. And then the question arose, is it possible to reflash this board and use it as an analogue of my favorite arduino. But I could not find documentation for this chip. Accordingly, I am looking for help in the implementation of my idea.
