different modules with just one update media
- sources git.toradex.com tag Colibri_T20_LinuxImageV2.5Beta2_20151106
- repository linux-toradex branch tegra
- repository u-boot-toradex branch 2015.04-toradex
Note:
- no SD boot integration yet but copying cbootimage to beginning of SD card
will at least boot
Known Issues:
- LP1 suspend might fail due to pending USB interrupts
- LP1 suspend might hang due to display controller issue
********************************************************************************
Linux Image V2.4 Beta 1 (May 18, 2015)
- U-Boot:
- update to U-Boot 2015.04
- new partition layout
- cbootimage/tegrarcm based update concept
- new NAND BCH ECC configuration able to fix up to 16 errors per 512 bytes
- enable ONFI detection, allows to retrieve more details about the NAND chip
- adjust config block and U-Boot environment locations in flash
- add generic Toradex config block handling, print exact product description,
board revision and serial number to the console
- add command to restore Toradex config block ("cfgblock create")
- add parallel RGB display support, display the Toradex logo and debug
console at VGA resolution by default
- optionally create device-tree properties which make board information
available from within Linux userspace through procfs (/proc/device-tree/
serial-number, toradex,board-rev and toradex,product-id)
- Linux kernel:
- enable module versioning support
- fix/improve optional 1-wire driver
- update MTD/UBI/UBIFS subsystem (infradead.org ubifs-v3.1 backport)
- new NAND BCH ECC configuration able to fix up to 16 errors per 512 bytes
- SPI driver fix number of words in transfer
- cleaned-up module configuration/deployment
- Linux user-space:
- migrate from YAFFS2 to UBIFS
- update OpenEmbedded from daisy to dizzy:
- glibc 2.20 (instead of eglibc)
- systemd 2.18
- Xorg 1.14.7
- updated various LXDE packages to newer versions
- build tegrarcm using static cryptopp library to avoid issues e.g. on 64-bit
Fedora
- replace full NTP daemon with systemd's NTP client only systemd-timesyncd
- blacklist USB RNDIS for connman, use systemd-networkd to configure RDNIS
network interface (new standard IP of the module is 192.168.11.1!)
- enable BusyBox resize command to resize the terminal on serial console
- sources git.toradex.com tag Colibri_T20_LinuxImageV2.4Beta1_20150518
- repository linux-toradex branch tegra
- repository u-boot-toradex branch 2015.04-toradex
Note:
- mount point names changed from /media/<block device name> to /media<label>
- no SD boot integration yet but copying cbootimage to beginning of SD card
will at least boot
Known Issues:
- LP1 suspend might fail due to pending USB interrupts
- LP1 suspend might hang due to display controller issue
********************************************************************************
Notes:
- 115200 baud serial debug console on UARTA aka FFUART (lower X25 on EvalBoards
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
- 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)
