Hello list,
I'm new to OpenOCD. Now I'm trying to make the config files for our new
eval board which use the ARM926EJS core. Many problems come up that I
can't solve alone.
Environment:
Eval Board and CPU core is ARM926EJS.
JTAG Adapter is a OpenJTAG compatible one (USB<=>JTAG).
Debian(etch).
OpenOCD is the lastest version from svnroot.
First please have a look my config files:
### interface.cfg ###
interface ft2232
jtag_speed 0
ft2232_vid_pid 0x1457 0x5118
ft2232_layout "jtagkey_prototype_v1"
ft2232_device_desc "USB<=>JTAG&RS232"
### flash.cfg ###
# flash bank <driver> <base> <size> <chip_width> <bus_width> <target#>
flash bank cfi 0x10000000 0x01000000 2 2 0
### target.cfg ###

if { [info exists CHIPNAME] } {
set _CHIPNAME $CHIPNAME
} else {
set _CHIPNAME arm926ejs
}
if { [info exists ENDIAN] } {
set _ENDIAN $ENDIAN
} else {
set _ENDIAN little
}
if { [info exists CPUTAPID ] } {
set _CPUTAPID $CPUTAPID
} else {
# From ARM926EJS Tech Ref Manual
set _CPUTAPID 0x07926F0F
}
if { [info exists FLASHTAPID ] } {
set _CPUTAPID $FLASHTAPID
}
if { [info exists BSTAPID ] } {
set _CPUTAPID $BSTAPID
}

}
$_TARGETNAME configure \
-work-area-phys 0x300000 \
-work-area-size 65536 \
-work-area-backup 0
That's all my current file. When I run openocd, I got following output
and I'm sure something must be wrong.

The init chain lines show the faliure but I've no idea why. I'm not
familiar with OpenOCD and its config things. The config files is also
from $INSTALLDIR/lib/openocd/... and with just a few changes(at
interface and flash part).
The questions as below:
Are there somethings wrong in those files?
When reset-init will be called and what's the function? How can I know I
need this? From core's datasheet?
Any help is appreciated. Thanks in advance.
