Hello,

I am trying to use JTAG debugger.

The cable is JTAGBLUE as in (http://docs.blackfin.uclinux.org/doku.php?id=hw:jtag:jtagblue)

And I followed the connection in the web link above,

Then I ran

ac@ac-desktop:/opt/uClinux/bfin-uclinux/bin$ ./bfin-gdbproxy bfin --connect='cable igloo parallel 0x378'

GDBproxy comes with ABSOLUTELY NO WARRANTY; for details

use `--warranty' option. This is Open Source software. You are

welcome to redistribute it under certain conditions. Use the

'--copying' option for details.

Initializing parallel port at 0x378

Error: Cable initialization failed!

error: bfin: cable initialization failed

cable: syntax error!

error: bfin: cable initialization failed

cable: syntax error!

error: bfin: cable initialization failed

I think my command line arguments for bfin-gdbproxy could be wrong. Do you know the correct arguments?

Thank you.

Regards,

"cable initialization failed" means the cable wasnt found. check your hardware is properly connected and that the parallel port settings are actually right. you can test with the urjtag interface directly with `bfin-jtag`.

Hi Mike,

I check the parallel port on my PC

ac@ac-desktop:~$ cat /proc/ioports

0000-001f : dma1

0020-0021 : pic1

0040-0043 : timer0

0050-0053 : timer1

0060-006f : keyboard

0070-0077 : rtc

0080-008f : dma page reg

00a0-00a1 : pic2

00c0-00df : dma2

00f0-00ff : fpu

0170-0177 : 0000:00:06.0

0170-0177 : libata

01f0-01f7 : 0000:00:06.0

01f0-01f7 : libata

0290-0297 : pnp 00:02

0376-0376 : 0000:00:06.0

0376-0376 : libata

0378-037a : parport0

So the port address 0x378 is correct, and I also saw "/dev/lp0".

And I used 'bfin-jtag' and tried several cable names, but all were failed. Here is the message

jtag> help cable

And I checked the wiring again, the wiring is correct. By the way, jtag pin 1 to jtag pin 7 was conneted for grounding and a 500 ohms resister was connected between jtag pin 10 and jtag pin 5.

Do you have any suggestion? Thank you.

Hi Mike,

Thank you.

Becasue there is no name for JTAGBLUE, so I just tried the different names and saw what would happen.

Here is the parallel port info on my PC:

ac@ac-desktop:~$ dmesg | grep parport

[ 35.460692] parport_pc 00:09: reported by Plug and Play ACPI

[ 35.460735] parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE]

[ 37.030256] lp0: using parport0 (interrupt-driven).

ac@ac-desktop:~$ ls -l /dev/parport0

crw-rw-rw- 1 root root 99, 0 2008-12-22 11:22 /dev/parport0

ac@ac-desktop:~$ ls -l /proc/sys/dev/parport/parport0/devices/

total 0

-r--r--r-- 1 root root 0 2008-12-22 13:54 active

dr-xr-xr-x 0 root root 0 2008-12-22 13:54 lp

But the connection still failed.

jtag> cable IGLOO parallel 0x378

Initializing parallel port at 0x378

Error: Cable initialization failed!

What am I mising? Thank you.

Hello Robin,

Thank you. But when I specified 'Wiggler', the connection was fialed too. The power up owner of /dev/parport0 is lp scanner, not root root. Even I changed the ownership, it didn't work either.

As you can see as below. Thank you.

Hello Robin,

Do you know where is the problem?

Is it in my PC's setting? If it could be the probelm of the jtag cable, could you advise where to get a Wiggler cable?

Thank you.

All I can say - is it works for me. Something on the host side seems like it is not working. It will be a few weeks before I get back to a PC with the Wiggler, and a parallel port.
