I can confirm that r19519 breaks the channel display, it's says UNKNOWN now. In fact I was going to report that right after the upgrade but I thought it was just me. How the ticket for DIR-632 can be opened so the issue is fixed?

I bricked my DIR-632 with a bad flash. Does anyone know the pinout for the jtag? It looks standard but I want to be sure. I have searched quite a bit and found a vague answer but hoping for some definite info. Thank you.
Yes, I have a printer port. I have those pages bookmarked already. I'm just getting my ducks in a row here and hoping for a little info. If anyone has any knowledge of the pinout numbering on this board I would appreciate the info.
This is all I've found searching for the pinout. This is a DIR-615 pinout. Would it be the same? I can see that the square hole is #1. So is it 1-7 down the first row and 8-14 on the second row?
The correct & conventional pinout for pin headers is supposed to be odd numbers on one side & even on the other side. Since many designers don't seem to know this, I have seen it done wrong as many times as done correctly.
You should be able to figure it out by ohmming out the GNDs on the DIR-632 & see if they match the DIR-615.
If you can find a copy of IEEE Std. 1149.1-1990, it might specify pinout. Designers are supposed to follow the spec, but many don't.
Found Std., it doesn't specify pinout.
BTW, if your DIR-632 is less than 1 year old, D-Link will replace it under warranty. Just don't tell them you were trying to reflash it. Tell them it stopped working. The factory firmware is so bad, I have no qualms about suggesting this.
Ok, they didn't honor the warranty. I don't have the receipt anymore.
I have some info from Brainslayer. He said the serial port works for erasing the nvram and kernel. The bootsector seems to be fine. The pinout on the serial header is much easier to figure out with an ohm meter. I have ordered an adapter, recommended by Brainslayer, that should do the job. After the adapter comes I'll give it a shot and post back.Thanks again Cmp_Cmndo.
Yes I was very pleasantly surprised to contact Brainslayer. I have ordered this adapter from ebay.
When it gets here from China I will let you know how it goes. I have soldered on a 4 post header for the serial port. I also ohm'ed it out and found the square hole to be the 3v contact. but I think all I need is the RX, TX and ground to make this work.
You should be able to figure out PWR & GND, power it up & use the voltmeter to read +3.3VDC. How to determine Tx & Rx is a different matter. If you get Tx & Rx reversed, it will do no damage, just won't communicate.
