Sanei N90

This is the "single core" version of the Sanei N90. There's also a "dual core" version which looks externally similar, but uses the Rockchip RK3066 instead of the A10.

= Identification =

In Android, under Settings->About Tablet, you will find:


 * Model Number: M9701
 * Build Number: crane_anpei-eng 4.0.3 IML74K 20120622 test-keys

= Sunxi support =

Current status
Everything appears to work with linux-sunxi's kernel except for the cameras.

CyanogenMod Jellybean compiles and works, except for the camera application.

Manual build specifics

 * For building u-boot, use the "Sanei_N90" target.
 * The .fex file can be found in sunxi-boards as sanei_n90.fex.

Everything else is the same as the Manual build howto.

= Tips, Tricks, Caveats =

Display
To enable the internal display, pass "disp.screen0.output_type=1" as a kernel argument, as per the Fex_Guide.

Wifi
Load the 8192cu module.

Touchscreen
Load the ft5x_ts module.

Accelerometer
Load the bma250 module.

Camera
As shipped, the device has "gc0308" and "gc0308b" modules loaded for the two cameras. Source for the latter doesn't appear to be available, but disassembling the two binaries shows that they're identical except that references to "client->addr" (the camera's I2C address) in "gc0308" have been changed to "0x21" in "gc0308b", and the "CSI_SUBDEV_PWR_OFF" handler in "sensor_power" calls "csi_gpio_write" rather than "csi_gpio_set_status". The hardcoded I2C address doesn't match the one in the shipped .fex file.

FEL mode
The Vol+ button triggers FEL mode.
