Hello,

Any idea on this JTAG problem on Calao USB A9263 ?

Thanks!

 Hello,
 
 (Resending to the list @berlios.de since the list
 @lists.sourceforge.net doesn't seem to work)
 
 I am trying to use OpenOCD 0.5.0 on the Calao USB A9263 board. This
 board is based on the AT91SAM9263 SoC and uses a built-in FTDI 2232 to
 provide USB access to the JTAG interface.
 
 The problem is that OpenOCD is not able to halt the target (I'm trying
 to halt while the board runs U-Boot, so there is no Linux running
 doing some crazy power management stuff). Here is what I get on the
 telnet interface:
 
 $ telnet localhost 
 Trying 127.0.0.1...
 Connected to localhost.

 Halt timed out, wake up GDB.
 timed out while waiting for target halted
 in procedure 'halt'
  halt  
 Halt timed out, wake up GDB.
 timed out while waiting for target halted
 in procedure 'halt'
 
 Here is what I see on OpenOCD output:
 
 $ ../src/openocd -f ./interface/calao-usb-a9263.cfg

 In case it is useful, I have attached the output of openocd started in
 debug mode.
 
 Do you have any clue of what's going on ?
 
 Thanks!

1. Try changing the speed of JTAG to be 1/8th of core speed.
2. Try doing reset halt from the telnet first.
3. Make sure your board has the same reset configuration as you pass to OpenOCD 
- separate lines of TRST and SRST.

 1. Try changing the speed of JTAG to be 1/8th of core speed.

I have tried with adapter_khz 5 or jtag_rclk 2, and not better. Since
the JTAG is capable of finding the tap/device, doesn't that mean that
the communication is working, and thus that the jtag speed is correct?

 2. Try doing reset halt from the telnet first.

It does reboot the board, but still can't halt the target. Output of
the telnet connection:

$ telnet localhost

 3. Make sure your board has the same reset configuration as you pass
 to OpenOCD - separate lines of TRST and SRST.

From my reading of the schematics, it seems it does, but I'm not an expert. The 
schematics of
the USB A9263 are available at
http://www.calao-systems.com/repository/pub/EMBEDDED%20COMPUTERS/USB-A9263-XXX/C02/HARDWARE/SCH-7-B01.pdf
(FTDI 2232 routing is on page one).

Any other suggestion?

 What's the core speed of your chip?

It's a AT91SAM9263 at 180 Mhz.

 Probably something high, so try high speed of JTAG - 1000 kHz (1MHz)
 - 5kHz is really slow, rclk 2 should give something like 2MHz
 (6MHz / (2+1)), but I'm not sure what it will do if JTAG adapter does
 not support adaptive clocking (FT2232D does not).

jtag_rclk sets the clock to 2 khz (which I tested originally), so I
tried 2000 khz instead. Not better.

 You may also try reset_config srst_pulls_trst or other
 configurations...

Not better, unfortunately. Still the exact same behaviour. Here is my
interface file:

Notice that first you set srst_pulls_trst and then another config file sets 
that back to separate. Try adding the command to openocd call:
openocd -f ... -c reset_config trst_and_srst srst_pulls_trst

Sorry, no more ideas from my side... Maybe someone else will be able to help 
you.

Generally the code you are running on the chip can be somehow blocking JTAG 
access so, if you can, try halting chip with empty flash. I think (I'm not 
sure) that issuing poll command from telnet performs the check of 
communication...

Please provide a debug log (run OpenOCD with -d 3 option) - maybe there is 
something interesting...
