Ok, original TP-Link uboot is refusing to accept images without
TP-Link header and lacks many useful commands, so I reflashed mine
TP-Link with alternative U-Boot to quickly check, will it boot FreeBSD
or not.
In case someone else wants to do it too, here is what I did:
1. Downloaded compiled pepe2k uboot
(https://github.com/pepe2k/u-boot_mod) from
https://raw.githubusercontent.com/gwlim/Openwrt_Firmware/master/TP-Link_TL-WDR3500-3600-43XX-WM4350R/TP-Link_TL-WDR3500-3600-43XX-WM4350R_Overclock_Section/uboot_for_tp-link_tl-wdr3600-43x0_oc_600_400_200.bin
2. Flashed from original TP-Link uboot:
tftpboot 0x80800000 uboot_for_tp-link_tl-wdr3600-43x0_oc_600_400_200.bin
erase 0x9F000000 +0x10000
cp.b 0x80800000 0x9F000000 0x10000
reset
3. After that FreeBSD started booting. Pastebin:
http://pastebin.mozilla.org/8156450
4. I should warn, that printenv is changed dramatically after this uboot update:
