1.8 Release Notes
Please look at the project page for more info. Some applications are built into the base gumstix-console-image with many others available installable from the package repository.
U-Boot has been updated to 2015.07 from 2014.10. Linux Kernel has been updated to v3.18 from v3.17.
The new uSD flash tool wic will format the root filesystem with ext4 for Gumstix images. U-Boot has been updated to work with this change - 63a83.
The mk2partsd shell script has been replaced by OpenEmbedded's WIC utility.
Please refer to the Section 6 of README in yocto-manifest. Additionally a guide of how to resize the root partition could be helpful.
Note that the root filesystem partition label is now changed to root, from rootfs.
Due to the way WIC tool currently works, un-commenting the UBOOT_ENV and SRC_URI_append lines in u-boot.inc file does not deploy the uEnv.txt file to DD-able image. Copying the file manually to the uSD is still necessary.
- 4eear - Caspa Camera module is now supported by the Device Tree kernel
- 4eear - NAND PoP is support is added to Overo Kernel DTS and U-Boot. Both Linux Kernel and U-Boot use BCH8
- 4eear - WiLink8 support added
- 4eear - TobiDuo and Arbor43C expansion boards have DTS
- 63a83 - Expect EXT4 root filesystem
-
