Where do we see the bootloader info?

[webcan]

HI! I just loaded to the merlin version Rt-n66u_3.0.0.4_270_26b.trx and now I want to check what version of the bootloader I have. to see if its the 32 or the 64 version.

PLEASE HELP ME I have been reading for about 4 days and still not cannot find a clear answer. ( I must have over loaded it somewhere I guess )

I also tried loading ddwrt but susseded once but now I can no longer aaccess any version of ddwrt that I flash ( only the stock version can I flash and access now for some reason) so now I want to see if at lease I have the correct bootloader version but I cannot seem to find were this info is located?

Found it, using the merlin version I found it under Tools>Sysinfo
My bootloader (CFE) is 1.0.1.2

So now I need to update it to 1.0.1.3.

Is it true that there is a version of merlin that updates the bootloader automatically upon flashing? or do we still need to do this manually?

Thank for you reply

No. What the Asus firmware and mine do (and some Tomato builds as well) is to manually increase the size they use for nvram. So even tho the bootloader says "32", the firmware uses an extra 32 KB. But you still have only 32 KB native support, and won't be able to flash DD-WRT with 64 KB support - a CFE upgrade is still needed.

Thank you very much for clearing that up. I did installed WINSCP and connect using SCP protocol.

1: Where do I look for the old CFE file? or does your script take care of that?

I have your file in unpacked in G:\1\ IN Winscp there is a "Open terminal" under Commands in the menu items, is this what I use to issue the commands?

Since I already have the file I dont need to issue the first set of command though the path is different.

do I use this "g:/1/cfe_update.sh /dev/mtd0ro" ( assuming the target is the router since its connected in session with it ) or do I have to extract the files to the router? and then issues the command in the terminal window?

I just tried to copy the files to /tmp/home/root and then execute your command but it returns and error code 126. Permission denied . What am I doing wrong?

HI! solved one ussue only to be onto another that I solved as well.

NOTE: YOU MUST COPY THE FILE OVER TO YOUR ROUTER FIRST THEN EXTRACT WITH TAR OR THE PERMISSIONS WILL GIVE YOU ERRORS.

Once you have extracted the files on the router then you may proceed to execute the script.

after that all should be good!!!

---------------Another issue users may run into--------------------

The script hangs in Winscp at the "READ" command. "Which could be due to WInscp not able to understand it which maybe because I have to add it in"

For whatever reason what I did is edit the script and removed a few line at the end.

You can edit the file in WinSCP ( Just right click and select "edit")

Then look for the following paragraph and modified it with the one at the bottom of this post.

NOTE: Be careful as with my modification there is no warning nor any pause so make sure that you run the original first and see if you have the old version that needs updating and then and only then edit the script if WinSCP hangs at the READ line.
