When you hit "RESET" in OCD commander, if the board is not powered on, 
or your JTAG connector isn't seated on the board properly, you'll get a 
little error message in the bottom left of the screen saying 
"CABLE_DISCONNECTED" or something like that.  If you get no message 
when you hit "RESET", then your connection is good.

The power-on problem seems to be resolved with the corrected RAM 
refresh timing code during board initialization -- it was apparently a 
software problem in the initialization code for the PXA that Intel's 
tools spit out, at least for the ~20 boards which demonstrated the 
symptoms Benny's described to us in the past with which we've tried the 
new RAM refresh code.  I was very surprised too, but it definitely 
seems to have been the cause.

[Craig Hughes <craig@hu...>]

We've gone back to all the boards we had which used to have the 
power-on problem that were in our "rejects" bin at gumstix, and with 
the new RAM refresh rate, all of them now behave correctly -- that is, 
the power-on problem seems to have been that some boards were more 
sensitive to the bad RAM refresh rate, and that this manifested itself 
particularly when power to the board was not switched on cleanly.

Re: SV: [Gumstix-users] turned my stick into a doorstop

[Craig Hughes <craig@hu...>]

Benny, not sure how you're starting up.  The way I do jtag with OCD 
commander is to connect the wiggler to the 'stix, then power up the 
'stix and quickly hit the "reset" button in the OCD commander toolbar, 
which will reset the board and halt.  Then I normally step an 
instruction at a time.  What should happen is that the first 
instruction at address 0 in flash should be a branch to a little above 
2k in flash, followed by the initialization code.  I generally find it 
useful to be looking at a copy of the output of "arm-linux-objdump -S 
u-boot" from the buildroot/build_arm/u-boot-1.1.1 directory at the 
time, so I have a nice, commented, version of the u-boot source code 
side-by-side with what I'm looking at in OCD.

I'll check and MD5 the images.  Also, I've now got the linux mtd flash=20=

Thanks for the suggestion. I'll put jumpers on the board to enable them or
not. It's not clear to me whether or not a 74HCT244 will work on a 3.7V supply
that I use. Maybe a 74LV244 should be used? In any case, I can always choose to
run the gumstix on 5V whilst I jtag debug I guess. The shops around here don't
have any low voltage chips, I'd have to order them.

Ah, great! I assume by buddy board you mean the way small computer? And the pads are the 20 pad area on it?

This is useful, now the attachment I was trying to read was the new jtag scripts. That would make the exercise complete I think.

Once you have OCD commander talking to the 'stix, you need to poke a 
few instructions to the PXA controllers before you'll be able to 
actually do a "go 0" or anything like that -- you won't be able to talk 
to flash or RAM before you initialize those systems.  Basically at 
power-on you can only talk to the CPU, which is where the intialization 
scripts come in -- we know which instructions to poke to the 
controllers in what order...

The script's now attached to the JTAG page on the wiki (click on the 
attachments tab).

I think Gordon is working on looking at being a reseller for the 
Macraigor wiggler too.

Re: [Gumstix-users] Gumstix USB connection to Mac Host?

[Craig Hughes <craig@hu...>]

I've tried looking at hooking the gumstix to a Mac, and had similarly  
little success.  There are a handful of CDC ethernet drivers for the  
mac floating around, including one which appears to be built-in to  
MacOSX 10.3.4 (not sure when it appeared, but it's on my 10.3.4 mac in  
/System/Libraries/Extensions/IOUSBFamily.kext/Contents/PlugIns/ 
AppleUSBCDCEthernet.kext).  Source code for a driver with the same name  
is on the Apple developer site, but the docs there say that it's not  
really working and is just a guide on how to create such a driver or  
something to that effect.  There's another driver out there (search for  
AJZaurusUSB), which claims to work with Zauruses, and I would have  
thought ought therefore to work with gumstix, but I wasn't able to get  
it working after installing it.  Part of the problem is that I can't  
really find any docs on how OSX decides what driver to load in response  
to a USB event -- somewhere I imagine there must be a mapping file  
which maps USB ids to drivers -- if so, then probably all that needs to  
be done is add the linux CDC ethernet gadget's id to the file, and map  
to one of the CDC ethernet drivers...

One other resource Benny didn't point out below is the Wiki,  
http://wiki.rungie.com/

I've just built a jtag cable interface, based on the description here

    http://jtag-arm9.sourceforge.net/

I just have to build the other side of the cable to interface to my old
version gumstix and I'll be ready to try as well. The short of it, is that I'm
also interested in the jtag scripts.

Hi

The latest firmware (binary) can be found on
http://sourceforge.net/projects/gumstix (complete jffs2 image including the
kernel so check the mail list regarding changing of u-boot environtment
variables which has to be changed if you have one of the old stix)
The source is now placed on a subversion server
http://svn.rungie.com/svn/gumstix-buildroot
Mantis bugtrack can be found on http://mantis.rungie.com

I have newer been close to a MAC so can't help you with that ;)

Re: [Gumstix-users] flash image and Uboot

[Benny Simonsen <benny_bs@ma...>]

I have build the JTAG mentioned below (or almost the same, but based on what
I could find at work) and it does look like there is some success with the
Windows version of OCD Commander.
I can write PC and get the same value back with speed setting = 4 (dont know
if 1 or 8 is the fastest) and processor = Intel PXA250 (guess this is the
one which should be used)

I can't use "go 0". If I try I get a "target bus error", but I don't know if
thats because i have to set some registers before I can do that.

Craig there seems to be some problems with the wiki pages (does reload all
the time) so I will really appreciate if you could send the script to the
mailing list.

Thanks
Best Regards
Benny

PS: Craig I agree that spending $100 on a known good JTAG dongle is fine,
but the problem is that I have to pay ~$60 to have it shipped to Denmark,
wait ~2 weeks before it arrives to Denmark, wait for customs who will
require 25% in sales tax + xx$ to the carrier for doing the customs
paperwork, wait a week before they have seen that my payment has arrived.
Thats why I prefer to heat up the solder iron. If you think the Macraigor
Wiggler is fine I would recommend you (Gumstix) to put it on the accessory
list so that people can purchase it together with there stix.

[Gumstix-users] Gumstix USB connection to Mac Host?

[Jay <jayprince@ma...>]

I wanted to inquire if anyone has used the usb gadget and an  
appropriate driver to enable a gumstix to talk to a Mac OS X machine  
over USB.

I've spent the last couple months working on a side project, and so I  
haven't been working with the gumstix... but when I last was, I had a  
custom kernel put out by Zach, and had a driver for OS X designed to  
let it talk to the Zaurus in this way.  It wasn't quite working, but  
the mac would complain when the IP address of the gumstix was the same  
as the mac ... so on some level it recognized that there was an  
"ethernet" connection there....

I'm going to start tracking these issues down, but I wanted to know if  
someone had already done it.

Also, where's the best place to get a latest firmware drop for my board?

Thanks all.

Jay
