+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 Image V1.2 (December 10, 2012)
+- update
+  - changed to unified WinCE/Linux loader, added Windows batch file
+    http://developer.toradex.com/software-resources/arm-family/linux/images/flashing-t20-linux-from-windows 
+- updated U-Boot
+  - fix to correctly reset Ethernet chip
+  - sanity checks, fail early when module is flashed with wrong module version / ram size
+  - use a generic approach to get the MTD partitions to ease changes to the partition layout
+    (Initial partition table parsing courtesy of Mitja Špes from LXNAV)
+  - added command 'enterrcm' which puts the CPU into recovery mode
+- updated kernel
+  - fix to correctly reset Ethernet chip
+  - added one wire platform data (conditional, CONFIG_W1_MASTER_TEGRA must be enabled)
+- rootfs
+  - no changes to V1.1
+
+********************************************************************************
+Linux Image V1.1 (October 31, 2012)
+- none, this version is identical to the previous beta version V1.1 Beta 2
+
+********************************************************************************
+Linux Image V1.1 Beta 2 (September 26, 2012)
+- updated BCT
+  - Colibri T20 V1.1c unified with BCT for other module versions
+- updated U-Boot
+  - SPI fix, U-Boot defined one pin to be GPIO which prevented SPI from working
+  - backlight GPIO switched on upon boot
+  - new environment variable 'setup' which makes e.g. carveout memory easily adjustable
+- updated kernel
+  - backlight PWM clock changed from 500kHz to 200Hz
+  - PWM B, PWM C, PWM D now accessible from userspace via /sys/class/leds
+- updated rootfs
+  - LXDM fix, interactive login also works now, not only autologin
+  - libnvodm_query.so fix, no longer configures GPIOs meant for NVIDIA's developer platform
+  - added evtest, test program to monitor input device events
+
+
+********************************************************************************

+- implement analog input AD0 aka ANALOG_IN0 as voltage_now and AD1 aka ANALOG_IN1 as temp value (see /sys/class/power_supply/colibri_t20-analog_inputs)
+- revise Ethernet MAC address assignment: should now use MAC from EEPROM if set and further handles up to two instances of custom user MACs (2nd one with a 0x100000 offset), this way customer does not have to put EEPROM on a secondary Ethernet on carrier board and still gets a valid official MAC address from us (e.g. analogous to how we do it on our Protea carrier board)
+- fix audio codec DAPM pin assignment (note this is only an issue if power management is to be used in the future)
+- fix regular framebuffer (e.g. /dev/fb0) access from userspace
+- fix GPIO flags direction during initialisation

+
+********************************************************************************
+Linux Image V2.0 Beta 2 (January 29, 2013)
+- U-Boot:
+  - code clean-up
+- Linux kernel:
+  - fix high speed UARTs, i.e. clocks could not be set for certain baudrates
+  - added thermal throttling, i.e. CPU freq. is reduced when CPU gets hot

+********************************************************************************
+Linux Image V2.0 Beta 1 (December 18, 2012)
+- U-Boot:
+  - SD boot fix
+  - add enterrcm command to allow manually entering recovery mode
+  - fix NVIDIA partition table parsing
+  - fix Ethernet detection fault
+- Linux kernel:
+  - added one wire platform data (conditional, CONFIG_W1_MASTER_TEGRA must be enabled)
+  - implement analog input AD0 aka ANALOG_IN0 as voltage_now and AD1 aka ANALOG_IN1 as temp value (see /sys/class/power_supply/colibri_t20-analog_inputs)
+  - unified Ethernet initialisation
+  - GPIO keys implementation
+  - USB OTG support
+  - USB gadget using Android function stack
+  - USB full speed limiting (see usb_high_speed kernel command line argument)
+  - USB device now reports 2 mA VBUS draw
+  - revise Ethernet MAC address assignment: should now use MAC from EEPROM if set and further handles up to two instances of custom user MACs (2nd one with a 0x100000 offset), this way customer does not have to put EEPROM on a secondary Ethernet on carrier board and still gets a valid official MAC address from us (e.g. analogous to how we do it on our Protea carrier board)
+  - fix VESA VGA graphics aka too much TuxTM issue
+  - using full PMIC power off which decreases power consumption but reset won't force a re-boot anymore
+  - implement Video-DAC power save for Iris
+  - LP1 suspend support (Colibri T20 512 MB on Iris draws around 180 mW)
+  - re-worked function tri-stating
+  - irq 68 nobody cared workaround
+- oe-core:
+  - L4T release 16-r2 userspace binaries
+  - update procedure: use loader.nb0 as the target binary, add .bat file for flashing from Windows, improved parameter checks, 
+  - configure RNDIS with Androids USB gadget
+  - dropbear: disable reverse DNS lookups, prevents timeout if no DNS Server is available
+  - add gstreamer plugins, nvvidconv Nvidia colorspace conversion, mp3 helpers
+  - xinput-calibrator: make the menu entry behaviour equal to the one time calibration on first boot
+  - added firmware for Ralink WiFi chipsets, e.g. WL250N USB WiFi stick from Ambicom
+  - add the rootfs builddate to /etc/issue -> Welcome banner
+  - add license information generated from oe-core and merge this with the Nvidia licenses in the common folder /usr/share/common-licenses
+  - kernel recipe: remove all fiddling with the defconfig, compile the kernel as it is in git
+  - header files for OpenGL, EGL, OpenMAX: taken from www.khronos.org
+  - firefox: set develper.toradex.com as the homepage

+
+********************************************************************************
+Linux Image V2.0 Alpha 2 (October 19, 2012)
+- update to L4T R16, !!!THIS REQUIRED TO CHANGE THE CALLING CONVENTION TO HARD FLOAT!!!
+- U-Boot:
+  - use a generic approach to get the MTD partitions to ease changes to the partition layout
+    (Initial partition table parsing courtesy of Mitja Špes from LXNAV)
+  - increase kernel partition size to 8 MB
+  - move the init output from the framebuffer console to the serial output
+- Linux kernel:
+  - implement analog input AD0 aka ANALOG_IN0 as voltage_now and AD1 aka ANALOG_IN1 as temp value. See /sys/class/power_supply/colibri_t20-analog_inputs.
+  - PWM B, PWM C, PWM D now accessible from userspace, /sys/class/leds/
+  - IPv6 enabled
+  - USB audio enabled
+  - PWM backlight fixed
+- oe-core:
+  - updated the different meta-layers
+  - change machine configuration to use hard float
+  - change OpenGL ES nvsamples to use hard float and not using pre-compiled shaders
+- sources git.toradex.com tag T20_LinuxImageV2.0Alpha2_20121019
+
+Known Issues:
+- LVDS aka TFTLCD resolution hard-coded in kernel to VESA VGA resolution, comments with timings for other resolutions provided
+- some gstreamer plugins, notably mp3decoding, h264encoding not working
+- some windows have garbled titlebar, e.g. lxterminal
+- lxappearance is segfaulting upon start
+- USB OTG port, not working
+- SD card boot copies only 4 MB from kernel (see further below for workaround)
+
+Calling Convention hard float:
+The way floats are passed in subroutine calls can be either in processor registers or
+in the floating point coprocessor registers.
+The processor register approach is used when gcc is called with -mfloat-abi=softfp or -mfloat-abi=soft
+The FPU register approach is used when gcc is called with -mfloat-abi=hard
+These two methods are not compatible with each other, all programs and libraries must be compiled
+either with softfp/soft or with hard.
+Thus all code used with Alpha2 must be recompiled. If you start a program which uses soft calling 
+convention you will get a 'No such file or directory' error, despite that the file exists and has executable permissions.

+Known Issues:

+- 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 VESA VGA resolution, 

+  comments with timings for other resolutions provided

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

+- lxappearance is segfaulting upon start

+- 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

+Linux Image V2.0 Alpha 1 (January 22, 2013)

+- U-Boot:

+  - moved to proper machine type

+- Linux kernel:

+  - added one wire platform data (conditional, CONFIG_W1_MASTER_TEGRA must be enabled)

+  - fix USB hang on device insertion

+  - added correct spidev platform data (/dev/spidev0.0)

+  - PWM B, PWM C, PWM D now accessible from userspace, /sys/class/leds/

+  - refined pin muxing

+  - added thermal throttling, i.e. CPU freq. is reduced when CPU gets hot

+  - updated audio codec driver, audio input now working

+  - GPIO keys implementation

+  - LP1 suspend support

+  - moved to proper machine type

+  - fix PMIC regulator platform data

+- oe-core:

+  - use latest u-boot and Linux kernel

+  - use latest GPIOConfig, fixes issues with tristated pins and GPIO with num >222

+

+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 VESA VGA resolution, 

+  comments with timings for other resolutions provided

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

+- lxappearance is segfaulting upon start

+- issues with the genext3.sh scripts: if your language settings expect 

+  something different to 'y' to a question, the script failes.

+  The rootfs is empty resulting in a kernel panic during boot.

+  Workaround: edit line 38 of bin/genext3.sh as follows:

+  old: echo y | mkfs.ext3 $@ -L arm 

+  new: mkfs.ext3 -F -L arm $@

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

+Notes:

+- 115200 baud serial debug console on UARTA aka FFUART (lower X25 on EvalBoards, X13 on Iris) 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)

+eMMC Boot: Colibri T30 V1.1b (Sample)

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

+

+Initial Preparation:

+- download and extract T30_LinuxImageVx.yz.tar.bz2 package

+

+Flash eMMC:

+- EvalBoard V3.1a

+  - connect USB B (X29) or USB micro A/B (X30) to development workstation using regular or micro USB cable

+  - the jumper JP2 must be open

+  - press and hold recovery mode switch (SW9) during power up

+- Iris V1.1a

+  - connect USB micro A/B (X12) to development workstation using regular micro USB cable

+  - short pin 1-2 of JP1 on Iris for RECOVERY

+(other carrier boards see http://developer.toradex.com/knowledge-base/colibri-recovery-mode)

+- make sure that the carrier board supports USB high speed

+  - Iris & EvalBoard V3.1a OK, for other carrier boards see http://developer.toradex.com/knowledge-base/usb-2.0-high-speed-%28480mbps%29 )

+- apply power or reset

+- run update.sh script

+

+Boot from eMMC:

+- EvalBoard V3.1a

+  - do no longer press SW9

+- Iris V1.1a

+  - do no longer short any pins of JP1

+- power cycle

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