This device is based on the Tegra 3. See the SoC page for common tips, guides and troubleshooting steps |
Notes
- Device SoC should be similar to SoC in Google Nexus 7 2012 and Google Nexus 7 2012 GSM
- OTG available - full support, connect and disconnect, at least USB keyboard-mouse and USB drives
partially (full USB port, working only when device connected before booting) - Battery charges (at least not discharges while OS work). Somehow reports status only in xfce4.
- Device have 3G modem (not working?)
- MiniHDMI port available (not working?)
- I accidentally broke my touchscreen connector on the motherboard, so I'm working with wireless USB keyboard-mouse now
Tested environments
- lxqt: works fine, can't manage to reboot or power off in UI, doing through terminal
- xfce4: starts only with startxfce4 in console, weirdly buggy
- console: works with connected wireless USB keyboard-mouse
- fbkeyboard: works, can't test touchscreen
Any other UIs is not working, or I can't get them to work for now.
How to enter flash mode
Press Fastboot Protocol
, then choose it by pressing .
Installation
We can install to sdcard now, so fastboot restrictions is now in the past.
pmbootstrap init
with vendor wexler and codename qc750pmbootstrap install --sdcard /dev/sda
pmbootstrap flasher flash_kernel
Partition limit: 8 MB
Legacy information, about flashing directly to the device:
pmbootstrap flasher flash_rootfs
It's possible to flash to userdata, but fastboot limit size of images is still to figure out (possibly 800 MB).
pmbootstrap flasher flash_rootfs --partition userdata
fastboot format system
