Recovery adfter Firmware upgrade

Sorry for the trouble. Please make sure if the SYS led of slave board flashes or not.

If the SYS led is off, i think the file system of slave board is broken. We need an USB-TTL cable to bring it up. Please prepare an USB-TTL cable and follow the manual to flash system firmware:

SYS led is off
It can blink for 1-2 seconds when i hold reset button and powering on, but after release remain off

Where can i get such cable, or maybe flash devise via tftp without cable ? like any other router using openwrt image ??

And another question

1.I found version of *.IMG firmware, other images are *.BIN. Can i use Bin images for flashing my device ?
2. In attached instruction
Check “rootmtdblock=/dev/mtdblockX” filed, if it shows “mtdblock6”, then execute “update
second” to flash firmware; if “mtdblock4”, then execute “update first”.

BUT my print says something like
What command should i use for update ?

Thanks .

Sorry for the trouble.

1) You can only flash .img firmware.
2) Here are the commands you need if rootmtdblock=/dev/ubiblk0_0 :
setenv ipaddr XXXXX
setenv serverip XXXXX
setenv fsfile wg400-current.img
setenv rootmtdblock /dev/mtdblock4
run updatefirst

nand erase offset size
nand erase 0x00100000 0x00080000
nand erase 0x00180000 0x00080000
