This post covers my music player with web interface that I’ve added to my workshop (or, perhaps, I’d better call it “my lab”?) In this post I will walk through the messy details of making such a box and document all the tricky bits.
In this small note I’ll tell you how to turn an old MediaTek SoC-based cellphone,(The one that’s probably gathering dust somewhere on your shelf, with no updates from vendor) into… a server running Debian Stretch! I’ve done this for UMI-X2 and iOcean X8 and you can download ready to flash firmware for these devices at the bottom of this post. Since a typical Chinese mtk cellphone now features 2GB or more RAM and 4 or more ARM cores the result packs way more performance than a typical Raspberry PI.
If you’re following my blog, you might’ve read my post about Dlink’s substandard engineering, and how I’ve got debian running on the damn thing. Well, since that time I’ve made a few improvements, namely:
- Power button’s now correctly rigged as well as the rest of the buttons.
- Upstream 3.18, 3.19 kernels now works flawlessly and don’t ever freeze. I update kernels with each new kernel release
- Goodies like Marvell’s DMA engine, mv_xor, watchdog and mv_cesa are all enabled for the win and are working awesomely
- There’s now a huge guide about ‘cooking’ the damned thing into a useable state in five easy steps. And you are reading it.
- Power measurements are all there as well!
