We are pleased to announce that there is a new TMPA9xx Linux release
available:
http://www.mucross.com/downloads/tx09-linux/Release-20110309/
Most major changes are on the Linux Kernel side:
- major improvements in the NAND driver
* upgrade recommended *
The NAND driver now properly supports UBI - UBI is now recommended for
new designs and enables faster boot time (the minimal image in the
rootfs subdir starts-up in about 10 seconds, not including u-boot
start-up time).
For hints on installing and switching rootfs types see
http://tx09linux.kernelconcepts.de/support/docs/getstarted/
Hint: If you are using NAND booting on a TOPASA900 board you may
experience problems after reset/power-up. See the following page about
possible solutions:
http://tx09linux.kernelconcepts.de/hw/boards/BMSKTOPAS900/
- major improvements in the I2C bus driver
* upgrade recommended *
- improvements in the SPI driver
- switch to ARM primecell drivers for
- UART
- I2C
- framebuffer
- en- and disabling UART ports can now be done in kernel config ("make
menuconfig")
- New abstractions in board files for TPMA - this allows easier adding
of custom board implementations
With this new release we changed the release directory structure. The
main directories are:
src/
Contains all relevant sourcecodes, U-Boot bootloader and
Linux kernel
The following directories contain ready compiled binary versions of the
released U-Boot and kernel as well as prepared root-filesystem images.
We hope that this improves overview over which files are needed to
support one of the supported boards:
tonga2/
u-boot/
U-Boot binaries
kernel/
kernel binary
rootfs/
some ready-to-run root-filesystem images
topas910/
u-boot-nor/
U-Boot binaries for NOR flash
u-boot-nand/
U-Boot binaries for NAND flash
kernel/
kernel binary
rootfs/
some ready-to-run root-filesystem images
topasa900/
u-boot-nor/
U-Boot binaries for NOR flash
u-boot-nand/
U-Boot binaries for NAND flash
kernel/
kernel binary
rootfs/
some ready-to-run root-filesystem images
openocd-cfg/
Contains Open-OCD configuration files for Linux JTAG usage
Please do not hesitate to give feedback to this release so that we can
improve - many thanks!
Kudos[1] to Thomas Haase and Michael Hunold or fixing a lot of stuff!
