Release Notes: Linux Image V2.x for Apalis TK1
***********************************************
Contents:
- U-Boot 2015.04 boot loader
- Linux 3.10.40 kernel, based on NVIDIA's Linux for Tegra (L4T) release R21.5
- Angstrom 2015.12/OpenEmbedded jethro/Yocto 2.0 based root file system, using
LXDE desktop environment
==> Flashing instructions can be found on the Toradex developer article:
http://developer.toradex.com/knowledge-base/flashing-linux-on-tegra-modules
Licensing:
- proprietary multimedia codecs included for evaluation purpose only
- customer required to obtain proper re-distribution license
********************************************************************************
Linux Image V2.6 Beta 2 (July 1, 2016)
- U-Boot boot loader:
- first release
- Linux kernel:
- first release
- Linux user-space:
- first release
- OpenEmbedded build system:
- integrate watatuki's meta-jetson-tk1 based on L4T R21.4
- first release
- sources git.toradex.com tag Apalis_TK1_LinuxImageV2.6Beta2_20160701
- repository linux-toradex branch toradex_tk1_l4t_r21.5
- repository u-boot-toradex branch 2015.04-toradex
Known Issues:
- power consumption under full load may exceed the carrier boards power budget
see http://developer.toradex.com/products/apalis-tk1#errata for more infos
- if no HDMI screen is connected pcmanfm will consume 100% CPU which can be
worked around by removing '/usr/bin/xrandr --output LVDS-0 --off' line from
/etc/xdg/lxsession/LXDE/autostart
- License texts do not get deployed to the root file system.
********************************************************************************
Notes:
- 115200 baud serial debug console on UARTA aka UART1 (EvalBoard lower X28 resp.
X29 depending on JP10/12, X22 on Ixora) without any handshake
- user account: root with empty password
- eMMC: partition 1: vfat with kernel, partition 2 ext3 root file system
- opkg package manager
- HDMI aka DVI-D: not all pixel clock frequencies allow for HDMI audio
- Linux host used for update preparation requires proper 32-bit execution
environment (e.g. install ia32-libs on 64-bit Ubuntu), awk and libusb
(e.g. install gawk and libusb-1.0-0 on Ubuntu)
