MSI Primo73

This is a brand name tablet from a reputable hardware vendor, so no problems with identification are expected. The tablet has a sturdy metal back cover and the overall build quality is good. However the TN display has relatively poor contrast and viewing angles (at least when compared with IPS displays).

= Identification = On the back of the device, the following is printed (the last model number part may be a bit different, depending on the color of the tablet and the country of origin): MSI Primo73 031PL

The PCB has the following silkscreened on it:

In Android, under Settings->About Tablet, you will find:
 * Model Number: Primo73
 * Build Number: Primo73-user 4.2.2 JDQ39 20131220

= Sunxi support =

Current status
Supported by the legacy u-boot-sunxi and sunxi-3.4 kernel. LCD display works. WLAN, touchscreen and accelerometer are untested yet.

The mainline kernel support is seriously hindered by the missing USB OTG driver. But WLAN can be used to connect with the outside world and at least do something semi-useful with the device. HDMI works. The LCD display is supported by recent patches, but they have not landed to the mainline releases yet.

Manual build

 * For building u-boot, use the "MSI_Primo73" target.
 * The .fex file can be found in sunxi-boards as msi_primo73.fex

Everything else is the same as the manual build howto.

Mainline U-Boot
A patch has been sent to the mailing list and if it gets accepted, then it will be possible to use MSI_Primo73_defconfig

For building mainline u-boot, use the  target.

Mainline kernel
A patch has been sent to the mailing list and if it gets accepted, then it will be possible to use sun7i-a20-primo73.dtb

Use the  device-tree file for the mainline kernel.

= Tips, Tricks, Caveats =

FEL mode
The VOL+ button triggers FEL mode. The button is directly connected to the UBOOT_SEL pin and drives it low when pressed (as can be verified by reading the BOOT_SEL_PAD_STA bits from VER_REG).
