This paticular flash chip is causing problems for tjtag, Im not sure about wrt54g "Hairy maid tool" ...I have no box with this flash chip so I cannot fully test what is happening, I suspect a timing issue, or something like that.
It will eventually flash, but you have to keep at it. I will look at it's datasheet again, and see if there is anything obvious. _________________ Want JTAG support - Donate a router

@Tornado
Sorry - been busy using my working router <grin>
The last time I tried to flash it, the command I used was tjtagv2 -flash:wholeflash /noreset. I couldn't ever get a flash to complete with a CFE or BSP. After flashing the wholeflash image, it reverted to the original Linksys firmware then went the normal route to put dd-wrt on it.
Only two thing I noticed are that sometimes it said the CPU entered debug mode and sometimes it doesn't. Unfortunately, I didn't see whether it was in debug mode or not the time it finally worked.
Also, I did try some of the quick power up and start flashing that I heard about around the forums, but when mine finally worked correctly, I had cycled the power and waited about 15 secs or so before I entered the command....
I don't know how much difference those two things make but that's what eventually worked for me - like I had said previously, this one was hard to flash. Keep trying if you have a GSv7. it does eventually work. I had tried it several several times before it worked and each time, NOTHING had happened at all with the lights and I was thinking that it'd never work, but it does!!

NP at all. You reminded me of something, I have a GS v7, and while testing flashing on it and trying to purposely brick it, I have noticed the same thing. It will sometimes get stuck, at 1% 4%, etc..and what I did instead of issueing the command as soon as I turned it on, was wait 5 sec's or so, maybe even a little bit longer...and that is what finally worked for me.
@felipe83
Try this, get your command line ready, and turn on the router, but wait about 5 seconds, and then issue your command...let us know. You may have to do it a few times.. _________________ Want JTAG support - Donate a router

Hello Tornado I comment to you that I have a box with a quite similar serial one to mine, I did all the backups to him, but I have tried to even load the CFE to him and nothing. When you say to me that I must use the command several times you talk about - flash: cfe /noemw?
thx
Tornado I trie and trie and nothing happen, the only thing that work was the forced reset to flash, the lan lighs are off, but dont had access to 192.168.1.1, what can i do, flash again?
yes, i had the static ip 192.168.1.50 to my computer. and the power led is continuously on off on off, another led is on are the network cable, i dont know if u understandme

I had same problem with you previously, after gone through many de-brick solutions for few months...
I revived it by changing the flash chip, and viola, 1 flash and success.
I found many people have the same problem with WRT54GL with samsung chip, once the cfe changed the router will brick completely.Maybe due to bad flash chip.
Good luck to you! _________________ WRT54GL V1.1 = 64MB ram,8MB flash,1GB 50X SD card,DD-WRT v24Mega SP1,2x Biquad,2x Serial port,Jtag, 12V 10mm fan,power on/off switch = MOD

It's great that you were able to do this, I doubt I could without some serious equipment. It is also not really a viable solution for most. There is a problem "or I just have not figured out the solution" for this chip...we will see, as I should be recieving a unit with this flash in it anytime. _________________ Want JTAG support - Donate a router

I agree with you.Its not worth the money as i already got the sd/mmc mod.Replacing the flash was my last resort to de-brick my router at that time.
Anyway just wanna share with those who share the same problem and can't wait for the fix :)
Good luck to you finding the problem as it can save many others with same problem. _________________ WRT54GL V1.1 = 64MB ram,8MB flash,1GB 50X SD card,DD-WRT v24Mega SP1,2x Biquad,2x Serial port,Jtag, 12V 10mm fan,power on/off switch = MOD

Hy Tornado
I asked to you informations about jtag software in more ways with no lucky
I don't know if you read messages or not so I tried to send to your dd-wrt private email a link with some informations about serial flashes used on foneras boards
you will find information about a numerous serial devices and about st-spi-flash
May be that comparing it to the others known devices you'll be able to understand what you need to introduce or modify on you Tjtag software...and make it working with "atheros + spi serial flash" boards
May be that this time I'll be luckyer than before because I see a great activity in this topic.
I hope to heard about you early thanks for your job
...and yes, I can send to you two boards for testing pourposes but I need some importants informations as your postal address for example
