+***********************************************

+Release Notes:  Linux Image V2.x for Apalis T30

+***********************************************

+

+Contents:

+- U-Boot 2011.06 boot loader

+- Linux 3.1.10 kernel, based on NVIDIA's Linux for Tegra (L4T) release 16-r3

+- OpenEmbedded oe-core 2012.10 based root file system, using LXDE desktop environment

+

+Licensing:

+- proprietary multimedia codecs included for evaluation purpose only

+- customer required to obtain proper re-distribution license

+

+********************************************************************************

+Linux Image V2.0 Alpha 1 (March 15, 2013)

+(ported form the Linux Image V2.0 Beta1 for Colibri T30)

+- U-Boot:

+  - first release

+- Linux kernel:

+  - first release

+- oe-core:

+  - first release

+- sources git.toradex.com tag Apalis_T30_LinuxImageV2.0Alpha1_20130315

+

+Known Issues:

+- We are in an early Alpha state, not all functions are tested.

+- If a a monitor is connected to DVI, the kernel sometime hangs when the 

+  display controller DC1 is initialised. -> reboot required. 

+- LVDS aka TFTLCD resolution hard-coded in kernel to full HD resolution, 

+  comments with timings for other resolutions provided

+- some windows have garbled titlebar, e.g. lxterminal

+- lxappearance is segfaulting upon start

+- Gigabit Ethernet MAC address hard-coded to 00:0e:c6:87:72:01

+- stability issues on concurrent PCIe and SATA stress testing

+- connecting an analog mic to the on module codec resets the codec, so that 

+  neither headphone out nor mic in works anymore. Workaround: Have mic 

+  connected before boot or change the output source between DAC/LineIn

+

+********************************************************************************

+Notes:

+- 115200 baud serial debug console on UARTA aka UART1 (EvalBoard lower X28 resp. X29 depending on JP10/12) without any handshake

+- user account: root with empty password

+- ext3 root file system

+- opkg package manager

+- HDMI: not all pixel clock frequencies allow for HDMI audio

+- CRT: the T30 internal video DAC output is unsupported by NVIDIA's L4T Linux SW stack

+- Linux host used for recovery mode flashing requires proper 32-bit execution environment (e.g. install ia32-libs on 64-bit Ubuntu)

+

+Working on latest image:

+- U-Boot boot loader

+  - environment storage in eMMC

+  - serial console

+- Linux kernel

+  - GPIOlib /sys/class/gpio (LVDS transmitter configuration)

+  - temperature sensor /sys/bus/i2c/devices/4-004c

+  - RTC (Tegra internal, PMIC and board level I2C RTC)

+  - Gigabit Ethernet eth0

+  - serial console debug UARTA aka UART1

+  - high speed serial UARTB aka UART3, UARTC aka UART4 and UARTD aka UART2

+  - I2C via /dev/i2c-X

+  - 8-bit MMC card mmc1

+  - 4-bit SD card mmc2

+  - PWM LEDs /sys/class/leds/

+  - HDMI HDA audio

+  - analog audio capture, playback and touch

+    - audio noise is high, workaround is to set headphone volume to maximum and use the DAC volume

+    - touch has some jitter

+  - SPI via /dev/spidev0.0 aka SPI1 and /dev/spidev4.2 aka SPI2

+  - USB host port

+  - USB audio driver

+  - USB webcam

+  - USB raw HID device /dev/hidrawX

+  - automatic USB device/host/suspend detection aka full OTG support

+  - suspend LP1

+  - CAN via can0 and can1

+  - PCIe (regular ports and mini-PCIe slot)

+  - SATA (regular port or mSATA slot

+  - parallel camera interface

+- Linux user-space

+  - graphics (LVDS-1 aka TFTLCD and HDMI-1 aka DVI-D)

+  - tegrastats

+  - Firefox

+  - Gstreamer video playback, dual full HD video decode

+  - LXDE

+  - tegrastats-gtk, CPU information visible in graphical environment

+  - LVDS transmitter configuration (see lvds-dual-channel.sh resp. lvds-single-channel.sh)

+

+Not working or not tested:

+- U-Boot boot loader

+  - eMMC with NVIDIA partition table parsing

+  - MMC/SD cards not recognized

+  - Toradex Apalis configuration block handling (i.e. all modules have the same MAC address)

+  - U-Boot USB keyboard

+  - Ethernet

+  - USB storage as host

+- Linux kernel

+  - analog input AD0 .. AD3 not implemented

+  - serial number and board revision

+  - watchdog

+  - USB device Ethernet RNDIS, provided by Android gadget

+  - framebuffer console

+  - custom Ethernet MAC Address

+  - HDA audio

+  - IrDA

+  - RS-422/485

+  - SIM card

+- Linux user-space

+  - Adobe Flash not provided by L4T (and probably never will)

+  - opkg package feeds seem to not be usable

+  - GPIO config tool missing Apalis MXM3 pin description integration

+

+**********************************************

+eMMC Boot: Apalis T30 V1.0a and V1.0b (Sample)

+**********************************************

+

+Initial Preparation:

+- download and extract Apalis_T30_LinuxImageVx.yz.tar.bz2 package

+

+Flash eMMC:

+- EvalBoard V1.0a

+  - connect USB micro A/B (X49) or USB B (X50) to development workstation using micro or regular USB cable

+  - connect serial debug console to lower X28 or X29 using null modem RS-232 or regular USB cable

+  - enter recovery mode:

+    - Eboot (e.g. transitioning from WEC):

+      - 9600 baud without any handshake

+      - hold space key while applying power or resetting

+      - press x to enter command mode

+      - use 'reboot rcm' command

+    - U-Boot (e.g. updating Embedded Linux):

+      - 115200 baud without any handshake

+      - apply power or reset

+      - hit any key to stop auto booting

+      - use 'enterrcm' command

+  - for more information about recovery mode please consult Apalis T30 datasheet chapter 6

+- run update.sh script

+

+Boot from eMMC:

+- EvalBoard V1.0a

+- power cycle

+- upon first boot post-install scripts are run which takes around 2 minutes, please be patient
