/** @page toshiba-ac100 Toshiba AC100
|
||||||
|
|
||||||
|
Toshiba AC100 is a Tegra2-based netbook.
|
||||||
|
|
||||||
|
The netbook has
|
||||||
|
@li NVidia Tegra 250 SoC;
|
||||||
|
@li 512 MiB DDR2 RAM;
|
||||||
|
@li 8 GiB internal e-MMC Flash Memory (some models have 32 GiB);
|
||||||
|
@li RS232 serial interface (LV-TTL levels on the board!);
|
||||||
|
@li SD card slot;
|
||||||
|
@li 2xUSB interface (miniUSB-B and USB-A connectors);
|
||||||
|
@li 10" LCD display (1024x600);
|
||||||
|
@li HDMI-interface;
|
||||||
|
@li touchpad and keyboard connected via I2C; the ENE KB926QF keyboard controller is used;
|
||||||
|
@li web camera;
|
||||||
|
@li some models have 3G-modem.
|
||||||
|
|
||||||
|
U-Boot master branch is working on AC100, but there's no support for the keyboard or the display.
|
||||||
|
|
||||||
|
barebox-toshiba-ac100 mini-howto:
|
||||||
|
|
||||||
|
1. Connect to the netbook's UART (see http://pecourt.ovh.org/wiki-tegra/doku.php?id=hardware);
|
||||||
|
|
||||||
|
2. Start U-Boot loader. See http://ac100.grandou.net/uboot and http://ac100.grandou.net/swarren_brain_dump for details.
|
||||||
|
|
||||||
|
3. If you use U-Boot with turned on display support, then switch to serial console:
|
||||||
|
@verbatim
|
||||||
|
Tegra2 (ac100) # setenv stdout serial
|
||||||
|
@endverbatim
|
||||||
|
|
||||||
|
4. Upload barebox.bin via Ymodem and start it:
|
||||||
|
@verbatim
|
||||||
|
Tegra2 (ac100) # loady 0x01f00000
|
||||||
|
Tegra2 (ac100) # go 0x01f00000
|
||||||
|
@endverbatim
