SinglWolf:

HI!
My router Tp-Link TD-W8970 v1.2 with flash 16M
u-boot is compiled from https://github.com/GreenTeaDev/u-boot/tree/tdw8970-16m and flashed in flash by the programmer
My modifications are in mypatch_18.06.1.patch
I downloaded the firmware of my own modification through UART
setenv ipaddr 192.168.1.1
setenv serverip 192.168.1.2
setenv bootargs 'board=WD8970'
tftpboot 0x80800000 openwrt-lantiq-xrx200-tplink_tdw8970-16m-squashfs-sysupgrade-end.bin
sf erase 0x20000 0xfa0000
sf write 0x80800000 0x20000 $(filesize)
reset

When I try to burn the same file, I get an error:
root@OpenWrt:/tmp# sysupgrade -v firmware.img
