Hello @hryamzik,

make tplink_wr702n

Where did you get that from? My modification doesn't include make command for WR702N model.

Please, try my prebuild image for WR703N from last release: https://github.com/pepe2k/u-boot_mod/releases/tag/2014-11-19

Cheers,
Piotr

@pepe2k, that's a typo, sorry, I've done this for 703n. 702n is the same router as 703n one. It misses a few smd parts (related to USB) and a USB port and has a smaller ROM. Will give this image a try, but I don't think the issue is related to u-boot itself.

Ok, got it working. Here's the correct way to reassemble the image:

v=703 sizeorig=4 sizenew=8
dd bs=1 skip=0                         count=$((128*1024))                  if=${v:-702}n.bin of=${v:-702}.orig/uboot.bin
dd bs=1 skip=$((128*1024))             count=$(((sizeorig*1024-64*3)*1024)) if=${v:-702}n.bin of=${v:-702}.orig/firmware.bin
dd bs=1 skip=$(((sizeorig*1024-64)*1024))                                   if=${v:-702}n.bin of=${v:-702}.orig/art.bin

mkdir -vp out
dd bs=1                                               of=out/${v:-702}n${sizenew}m.bin if="$uboot"
dd bs=1 conv=notrunc seek=$((128*1024))               of=out/${v:-702}n${sizenew}m.bin if=${v:-702}.orig/firmware.bin
dd bs=1 conv=notrunc seek=$(((sizenew*1024-64)*1024)) of=out/${v:-702}n${sizenew}m.bin if=${v:-702}.orig/art.bin
