How to enter flash mode
- Hold Power + Volume Down buttons
- Release Power button as soon as device vibrates
Installation
- Bootloader must be unlocked
- Bootloader from Android 4.0 firmware doesn't support standard bootimg format. Bootloader from Android 4.1 firmware or later should work
- Installation with
pmbootstrap flasher
should work, but currently only booting withkexec
has been tested.
Notes
GPU acceleration with the PowerVR SGX540 is not available, but the software based pixman renderer works quite well on the device's x86 CPU.
What works:
- booting pmOS with phosh
- installing applications
- browsing the web
What doesn't
- display brightness and color calibration
- When display is turned off and on again, color calibration isn't initialized and looks a bit weird.
- CPU-freq / CPU-idle / Powemanagement
- Device runs in full power mode and drains battery quickly
Mainline
The internal peripherals of the Intel Medfield SoC can be discovered by PCI and mostly already work with the mainline kernel drivers.
Device specific hardware like I2C and SDIO modules have to be discovered with Intel's "Simple Firmware Interface" (SFI). The mainline implementation of SFI was quite messy and has recently been dropped in newer releases.
