New U-Boot version for MediaTek MT76x8/MT762x based ALFA Network boards includes support for a 'dual image' feature. Users can enable it using U-Boot environment variable 'dual_image' ('1' -> enabled). When 'dual image' feature is enabled, U-Boot will modify DTB and divide the original 'firmware' flash area into two, equal in size and aligned to 64 KB partitions: 'firmware' and 'backup'. U-Boot will also adjust size of 'firmware' area to match installed flash chip size. U-Boot will load kernel from active partition which is marked with env variable 'bootactive' ('1' -> first partition, '2' -> second partition) and rename both partitions accordingly ('firmware' <-> 'backup'). There are 3 additional env variables used to control 'dual image' mode: - bootlimit - maximum number of unsuccessful boot tries (default: '3') - bootcount - current number of boot tries - bootchanged - flag which informs that active partition was changed; if it is set and 'bootcount' reaches 'bootlimit' value, U-Boot will start web-based recovery which then updates both partitions with provided image Signed-off-by: Piotr Dymacz <pepe2k@gmail.com> |

To build your own firmware you need a Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system. You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers installed. 1. Run "./scripts/feeds update -a" to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default 2. Run "./scripts/feeds install -a" to install symlinks for all obtained packages into package/feeds/ 3. Run "make menuconfig" to select your preferred configuration for the toolchain, target system & firmware packages. 4. Run "make" to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the Linux kernel & all chosen applications for your target system. Sunshine!
