i bought a second unit from this brand, one in may and one in august, i
discovered (confirmed from their support) that they ship the router with
two flavour , one with breed bootloader that i know is almost fully
compatible with openwrt 18.06.1 (doesn't work the wifi AP mode) and a
second version with u-boot bootloader
this second version , won't work with the same firmware , and if you
flash it , you brick the router (but you can flash the original firmware
loading it via TFTP and serial consolle)
the breed version has
OpenWrt 18.06.1, r7258-5eb055306f
root at OpenWrt:~# cat /proc/mtd
dev: size erasesize name

mtd6: 00a00000 00010000 "rootfs_data"
i have limited remote access to this router
the uboot bootloader have a 57600 serial speed, then i clone the openwrt
tree and change the serial speed into the dts file from 115200 to 57600
, i enabled in menuconfig target image -> ramdisk and compile
but when i try to load in ram (or flash it) i have some problem
here the bootlog
at line 1 the ram loading
at line 120 the flash and boot from flash
if needed i can share the serial bootlog for the original firmware
someone can point me in the right direction?
i cc the author of the commit that introduce the support for the breed
version, i hope is tollerate
