Hi everyone, Happy new year.

I an new in ARM controllers, starting with comStick from Hitex.
I want to use Eclipse for development.
My PC is running XP with driver "STR9_comStick_usb.sys" for
USB_Serial_JTAG from Hitex.

The comStick is tested with hitop, the Flash is programmed and is
running a programme, blinking the LED.

In the eclipse environment, I just want to start running the flashed
programme, so I run the following script with OpenOCD:

{
#log_output cs.log
debug_level 3

#daemon configuration
telnet_port 4444
gdb_port 3333

interface ft2232
ft2232_device_desc "STR9-comStick A"
ft2232_layout comstick
#ft2232_layout usbjtag
ft2232_vid_pid 0x0640 0x002C
jtag_speed 3
#jtag_speed 1
jtag_nsrst_delay 100
jtag_ntrst_delay 100

#use combined on interfaces or targets that can't set TRST/SRST
separately
reset_config trst_and_srst

#jtag scan chain
#format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)
jtag_device 8 0x1 0x1 0xfe
jtag_device 4 0x1 0xf 0xe
jtag_device 5 0x1 0x1 0x1e

#target configuration
daemon_startup reset

#target <type> <startup mode>
#target arm966e <endianness> <reset mode> <chainpos> <variant>
target arm966e little run_and_init 1 arm966e
run_and_halt_time 0 50

working_area 0 0x50000000 32768 nobackup

#flash bank <driver> <base> <size> <chip_width> <bus_width>
flash bank str9x 0x00000000 0x00080000 0 0 0
flash bank str9x 0x00080000 0x00008000 0 0 0

#Script used for FLASH programming
target_script 0 reset str91x_reset.script
}
------------------------------------------------------

I get the following debug log:

After that, the comstick starts running, but as you can see, there is no
proper connection with the JTAG.

Could be of any help changing the USB driver? Is there any mistake in
the script? Can anyone help me?

Thanks

script looks ok to me.
Try a newer version of openocd - should work but your version is quite
old.
Before you attempt to program, you need to get the connection working
first so try reset_halt rather than run_and_halt.

The script will need updating for the newer openocd, but there are
examples in the target/target dir of openocd.

Cheers

Dear Spen, Thank you for your reply.
Where can I find a more recent version of opeocd?
I got the 717 version of opeocd from Yagarto.

Hi Stelios,

thanks for your posting, your script is the solution for me. I adapted
my configuration with your changes and I got my comStick working.
I have the same version of OCD as you!

Hi,
I am also new to ARM programming and I also bought some STR9-comStick 
from Hitex.
I modified an example that now uses the RTC interupts to increase a 
counter nd does an output over UART. Unforunately, my code has 
apparently some mistakes and now I cannot connect to stick anymore.

Currently I am not using OpenOCD, but the Hitop for compilation and 
download and Eclipse for editing.

Is there any chance to access my comStick ever again?
I read that the stick is a bit picky on particular errors, as the JTAG 
is resettet with the processor and it takes some time until JTAG gets 
control.

Thanks for helping
cheers
Axel
