I want to change the boot loader on tplink 3220 that uses uboot.
I am trying to change the defauls serverip from 192.168.1.27 to the server on my LAN.
Also is it possible to make the default boot from tftp instead of from memory?
I can connect via serial and use setenv but there is no saveenv command available. Even if i set the uboot partition to not be read-only how would I save the changes?
-thanks
i suggest you download the source codes on TP's GPL site, as far as i knowe your uboot doesn't support the saveenv cmd.
so you'd better compile your owen one,
1,find the proper board relate h file in /include/config/yourborad.h (usually you can find your board name in the series printout messages like ap99 ap93 or db121 etc.)
2,find the config cmd micro it looks like #define CFG_COMMAND .... can't remember the exact name ,and add CFG_CMD_ENV
3,add #defien ENV_IS_IN_FLASH 1 ,and #undef ENV_IS_NOWHERE, #define ENV_ADDR the addr you wanna save at, #define ENV_LEN 0x10000 sooorry can't remember either but looks like these, and you can find them in the .h file
and run make youboard_config; make
then you will get a u-boot.bin file .but be careful about the file size if it's <128kB you should append FFFFFFF upto 128kB(no more no less) using a winhex or some other tool,also edit the MAC addr at offset 0x1fc00.
caution !!!!! your wrt may bricked

That is a little to risky for me I think. I tried to cat the mtd0 to a file and edit it in a hex editor but I am not able to write it back to mtd0 because it is locked. I tried unlocking it following the wiki instructions at http://wiki.openwrt.org/toh/tp-link/tl- … n.writable but it did not help me. I created a post about it at https://forum.openwrt.org/viewtopic.php?id=33170 but I am still stuck.
I don't reall want to brick this router but I do want to change some env settings and maybe even get it to tftp boot instead of booting from memory.
Just in case I try the (might) brick route this post: https://forum.openwrt.org/viewtopic.php?pid=149061 is basically what I need to do right? Just change the moodifications but the filling up to 128 is the same idea.
Also if its >128 then I am stuck?
-thanks.

good day
I need the rom ART.BIN router TL-MR3220, I see that you have enough knowledge.
dd-wrt installed, you can copy the block / tmp/mtd7 fimware which is the whole rom with the command (dd if = / tmp dev/mtd/7 of = / backup /. bin) and then just copy to your PC via winscp ok, thank you Brazil,
The discussion might have continued from here.
