Hey, guys! I need help, I almost got UAP v2 working on openwrt! Last problem left, my settings are not saved after reboot. It happens every time:
[ 60.311276 ] jffs2: Newly-erased block contained word 0xdeadc0de at offset 0x000000.
[ 60.319138 ] done.
[ 60.321162] jffs2: notice: (1280) jffs2_build_xattr_subsystem: complete building xattr subsystem, 0 of xdatum (0 unchecked, 0 orphan) and 0 of xref (0 dead, 0 orphan) found.
[ 60.761763] overlayfs: upper fs does not support tmpfile.
I have the same problem as here https://note.rajven.ru/?p=418 .What are the options for solving the problem, can you configure the settings to be saved to the 256k(cfg) section on a flash drive?
So, this is how I've been flashing the device:
- I found that mtd will unlock if I start flashing the device via UART and cancel the firmware in the middle of the process.
fwupdate.real -m BZ.qca9342.v3.7.37.6065.170118.0908.bin -d - Then I took the mtd utility from here unpacked and executed
./mtd -e kernel write openwrt-ath79-generic-ubnt_nanostation-loco-m-xw-squashfs-sysupgrade.bin kernel - I started getting an error:
[ 0.442204] VFS: Cannot open root device "(null)" or unknown-block(0.0): error -6
[ 0.449857] Please append a correct "root=" boot option; here are the partitions:

[ 0.484939 ] (driver?)
[ 0.491586] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0.0)
- I edited the file in the firmware of openwrt/target/linux/ath79/dts/ar9342_ubnt_xw.dtsi (sorry for making it so unprofessional)
&spi {
status = "okay";
num-cs = <1>;
flash@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <25000000>;
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "u-boot";
reg = <0x000000 0x060000>;
read-only;
};
partition@40000 {
label = "u-boot-env";
reg = <0x060000 0x010000>;
read-only;
};
partition@50000 {
compatible = "denx,uimage";
label = "firmware";
reg = <0x070000 0x740000>;
};
partition@7b0000 {
label = "cfg";
reg = <0x7b0000 0x040000>;
read-only;
};
art: partition@7f0000 {
label = "art";
reg = <0x7f0000 0x010000>;
read-only;
};
};
};
};
Eventually the dot loads, everything works, but I can't save the settings. What else do I have to do to get her to save the settings somehow?
