Because a bug in handling partial erase blocks in 4.19 kernel, using
sysupgrade images will hard brick devices that use RedBoot bootloader
and have "FIS directory" with "RedBoot config" on the same erase block.
Since flashing the devices from bootloader is safe, and to not cause a
situation where external chip programmer or JTAG is needed, disable
sysupgrade images for affected boards while creating kernel.bin and
rootfs.bin for jjPlus JA76PF2 board, which doesn't have factory image.
To set up the JA76PF2 board follow "Installation" instructions in b3a0c97
("ath79: add support for jjPlus JA76PF2") except the part of loading
initramfs image and using sysupgrade image for flashing (point 6 and 7).
Enter following commands to flash the board from bootloader:
fis init
load -r -b 0x80060000 <openwrt_kernel_image_name>
fis create linux
load -r -b %{FREEMEMLO} <openwrt_rootfs_image_name>
fis create rootfs
fis load -l linux
exec -c ""
For RouterStations use TFTP recovery procedure.

This is the buildsystem for the OpenWrt Linux distribution.
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!
