Known Issues:
- LP1 suspend might fail due to pending USB interrupts

********************************************************************************
Notes:

resp. X27 on V3.1a depending on JP17/19, X13 on Iris) without any handshake
- user account: root with empty password
- UBIFS flash root file system
- opkg package manager
- HDMI aka DVI-D: not all pixel clock frequencies allow for HDMI audio
- CRT: the T20 internal video DAC output is unsupported by NVIDIA's L4T Linux SW
stack

environment (e.g. install ia32-libs on 64-bit Ubuntu), awk and libusb (e.g.
install gawk and libusb-1.0-0 on Ubuntu)

*****************************************************************************************************************************************************************************************
NAND Boot: Colibri T20 256MB V1.1b (Sample), Colibri T20 512MB V1.1c (Sample), Colibri T20 256MB V1.2a, Colibri T20 512MB V1.2a, Colibri T20 256MB IT V1.2a or Colibri T20 512MB IT V1.2a
*****************************************************************************************************************************************************************************************
Initial Preparation:
- download and extract Colibri_T20_LinuxImageVx.yz.tar.bz2 package with root
permissions
- use any VFAT formatted SD resp. micro SD card with at least 1000 MB of free
space
- run update.sh script with -o argument pointing to mount point of above
mentioned card
Flash NAND:
- EvalBoard V3.1a
- depending on JP17/19 connect serial debug console to UARTA aka FFUART
(lower X25) using null modem RS-232 cable resp. X27 using a regular USB
cable
- insert above prepared SD card into SD/MMC socket (X15)
- Iris V1.1a
- connect serial debug console to UARTA aka FFUART X13 using null modem RS-232
cable and a 10 pin IDC to 9 pin D-sub male connector.
(DTK or Intel standard)
- insert above prepared micro SD card into micro SD card socket (X10)
- Boot to U-Boot prompt and start the update:
- apply power or reset
- hit any key to stop auto booting
- if you update from a previous image use the following U-Boot commands:
setenv drive 0
setenv setupdate 'mmc rescan; fatload mmc ${drive}:1 ${loadaddr} flash_blk.img; source ${loadaddr}'
saveenv
- use 'run setupdate' U-Boot command and then
- use 'run update' U-Boot command
- If you updated from an older image:
- power cycle or reset as requested and hit any key to stop auto booting
- use 'run setupdate' U-Boot command and then
- use 'run migrate_v2.3b7' U-Boot command
Boot from NAND:
- 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
If the boot loader on the module got corrupted this recovers it by loading
U-Boot over USB into the module's RAM and executing it there:
- 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
- connect serial debug console as stated above
- 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
- connect serial debug console as stated above
- short pin 1-2 of JP1 on Iris for RECOVERY
(other carrier boards see http://developer.toradex.com/knowledge-base/txx-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
- have the module in recovery mode and load U-Boot over USB to the module's RAM:
- lsusb should show a '0955:7820 NVidia Corp. Tegra 2 AC100 developer mode'
device if the module is in recovery mode
- run ./update.sh -d
- stop at the U-Boot prompt and begin the update as stated above using the
'run migrate_v2.3b7' command
