16  Hardware and U-Boot firmware / Hardware / Re: Help with GuruPlug JTAG connection on: May 21, 2010, 09:46:24 PM
Thanks for confirming that.

Now I am mystified.  Why does my serial input work, but not the serial output?

My problem is that my Guruplug and JTAG box does not produce any serial output, although I know that the serial input into the guruplug is working.

Can someone with a Guruplug and a JTAG adaptor do me a favor?

1) connect _just_ the JTAG adaptor to your PC via USB cable (do NOT connect the JTAG to the guruplug)
2) start your serial program (putty or whatever)
3) type characters into the serial program

The question is: when you type characters, do BOTH the TX and RX blue lights flash?  Do the characters you type get echoed to the screen, even if you have local echo disabled?

They do on my setup, even when I have local echo disabled.  It seems to indicate that my JTAG module is echoing the data that it receives.

On a whim, I tried disconnecting the UART cable (the 4-wire cable) from the guruplug.  I still get the local echo, which seems a bit odd to me, but it means that the jtag box is generating the echo.  Obviously, I do not get any response to what I type with the UART cable unplugged.

So: This means that my guruplug is not generating any serial output at all, even though it is recognizing the input.

I ohmed the UART cable, and it seems OK.  So I think my guruplug must be defective, unless I am overlooking something.

I double-checked, and my flow control is disabled.

I do get some output from the guruplug: the echoing of what I type.  That is the *only* output I get though. 

The guruplug sees what I type and echoes it, but I never get any other output from the plug.  I can type 'echo "FOO!"', and although I see the chars echoed to my screen, I get no output from the 'echo' command after I hit return.  And like I said, I can type 'reboot', and the machine reboots so it is definitely seeing my input.

I have a sheevaplug, and the jtag serial IO mechanism works perfectly using all the same programs and same settings.

I got a guruplug with JTAG box.  When I connect everything up and boot the device, I get no serial output as the device boots instead of all the marvbel/uboot text that should be scrolling by. 

The guruplug does boot though, because it does finally come up with 3 solid green leds and one blinking green LED.  At that point, if I type in 'root' and the default password 'nosoup4u', and then type 'reboot', the device reboots.  That means that the serial input is working. 

I checked the operation with 'local echo' on my terminal emulator program.  If I enable 'local echo', I get two copies of everything, as in:


(except that all the input is on the same line, meaning my <return> key is not generating a line feed)

If I disable local echo on my terminal emulator, I get:


(also all on the same line)

The doubling of the chars I type must mean that the device is echoing the chars that I am typing over the jtag serial.

Any ideas why I do not get any of the other output over the serial?  Is there something I need to do after logging on the guruplug to fully enable serial IO?

Am I doing something stupid?  (wouldn't be the first time)

I got mine today.  There was no CD inside.  I was hoping for documentation.  Did anyone get a CD with theirs?

I got a variant on that email today from user billiink on this forum.  It is a link to the same site: http://mimosa.org.ua/

Maybe you could nuke that account too.  Thanks!

Yes, I got it unbricked last night.  The windows version of the unbricker process didn't work (openocd was never able to talk to the device, in spite of seemingly having all the right drivers present).  The linux version worked though, so I am back in business. 

cbxbiker61: Thanks for adding the check on the mtd size.  That should save some trouble for others.  Also, thanks for making it so easy to upgrade the kernel!  Your README kernel upgrade executables kick butt!  ...and I gotta ask: do you ride a CBX?  That inline 6 must sound pretty good!

24  Linux Stuff / Kernel / Re: new release on: January 31, 2010, 02:34:33 PM
Yes, it is bricked.

This is my first-time kernel upgrade.  I tried the README script and I got:

Did my plug just become unbootable?  How do I recover from this?
