Device owners

  • Km2 (Notes: After flashing the plasma mobile, the device stopped loading and gets stuck on the bootloader logo. It looks like nand-memory is bad)
  • Knuxfanwin8 (Notes: mainline efforts; currently broken (boots for a few seconds and shuts down))
  • R (Notes: WIP postmarketOS port. Need to solder a new USB connector to test)


How to enter flash mode

Recovery: Power+VolUp Download/Odin: Power+VolDown

Notes

The device freezes under heavy load (such as installing certain apps through apk).

Audio works for a split second and then crashes.

Mainline status

Element type Element Status
Chipset BCM23550 DTS in mainline
Graphics Videocore IV https://github.com/anholt/mesa/wiki/VC4
USB FSA9485 There's a fsa9480 driver which is pretty similar, so downstream will need to be compared.
Touchscreen MELFAS MMS144 Driver in mainline
WiFi, Bluetooth BCM4330 Driver in mainline
Display HX8369 and/or SC7798 HX8369 is in mainline, SC7798 is not. Both are enabled in the kernel config. Only SC7798 is present in my Grand Neo (TODO: There's apparently a dual-sim model. Does that use the same display?)
Camera Samsung S5K4ECGX and db8v61m s5k4ecgx is in mainline, db8v61m is only in Broadcom downstream. (TODO: Which one is the front-facing camera and which one is the main one?)
PMU BCM590xx Driver in mainline.
Backlight KTD3102 Not in mainline, and there doesn't seem to be a similar driver (by name).
Proximity/ambient light sensor Sharp GP2AP002 Driver in mainline
Geomagnetic Alps HSCDTD008A Driver not in mainline
Accelerometer, magnetometer Bosch BMC150 Driver in mainline

Some information:

  • There's a DTS in downstream but it's unused and the parts used don't match the defconfig. Seems like it's a generic tree and was never finished, as it matches some stuff in the board-java.c file in downstream.
