I have built an MAX232-serial converter and it works, but I can't get my new Buffalo WHR-G300N to take the firmware.bin no matter what I try... Any one knows what I am doing wrong?
Here is snippet from log from the part G300N tries to get the firmware.bin from my computer/TFTP server:
Code:
ETH_STATE_ACTIVE!!
Using Eth0 (10/100-M) device
TFTP from server 192.168.11.2; our IP address is 192.168.11.1
Filename 'firmware.bin'.
TIMEOUT_COUNT=10,Load address: 0x81000000
Loading: *Got ARP REPLY, set server/gtwy eth addr (00:11:25:2e:91:c6)
Got it
Got ARP REQUEST, return our IP
T T T T T T T T T Got ARP REQUEST, return our IP
T
Retry count exceeded; starting again
This loops to infinity...
I have tried tftpd and tftpd-hpa and placed firmware.bin to TFTP server root, is this correct way?

Do you have a diagram of the serial port on the board for WHR-G300N..?? how you made it..
Well I am planning doing more "robust"/better rs232 buffer cable than currently, maybe I'll remember to document it too...
But lets say first pin is the square one, that is a 3.3v power (leg 16 of max3232, you need to add 5 volt regulator and take power directly from power intake if using traditional max232 chip), second goes Tx1 in (leg 11), third pin goes Rx1 out (leg 12) and last one is GND/minus (leg 15)...
I'm planning on doing a rs232 dongle that has max3233 built in so only thing needed is to solder header to any given device. Max3233 because that doesn't basically need any extra components like traditional max232 does, so it will fit much more easily inside DB9 casing (I hope).
And propably I will tweak my own devices so that they will have rs232 on them so I need only normal rs232 cable for console connection.

I recently bought a WHR-G300N and want to flash it with DD-WRT using a serial level shifter. Based on olmari's post I've done a picture of the serial header.
Can someone confirm the correctness of the serial header pinout attached?
If it is correct, maybe someone can add it to the WHR-G300N Wiki page as well:
Hello! I just modified and flashed my router successfully with a DKU-5 cable. But after I did a 30/30/30 reset, the router was bricked with the red DIAG light flashing twice every few seconds.
When I logged in through the terminal again, I saw the firmware being loaded and then a "Bad CRC in EEPROM" error message, thus halting the startup with the red light flashing. Has anyone else experienced this?
At least I can connect with serial again. I will try to flash it once more to fix this problem.
No good. I tried flashing older versions of the pre-SP2 firmwares, using WinAgents TFTP Server instead of TFTPD32, playing with the reset button again and switching ethernet cables. (I am on Vista Ultimate SP1). Now DD-WRT hangs when I change the initial username/password, which I guess means that something is going wrong with the firmware transfer.
I guess I have to install Linux and atftpd next? Oh boy.

Or just go again to 192.168.1.1 and it works? Afaik DD-WRT have had that "initial password change blankscreen" as long as password change became neccesity...

Or, how does it hang actually?
Hi olmari. Yes, I believe it hangs because I've tried to re-load the admin page after changing the password but it never finishes. The ctrl-C error message is also still there. Does "checksum bad" or "Bad CRC" mean that the uploaded firmware is bad, or did the 30/30 reset ruin the checksum procedure?
I'm pretty sure I switched on the router twice without issues, before the 30/30 reset.
