The only external cfg file I sourced in is interface/jlink.cfg. I think
I don't use other tcl files. Below again I paste my openocd.cfg:
------------------------------------
gdb_port
tcl_port
telnet_port
source [find interface/jlink.cfg]
adapter_khz 500
set _CHIPNAME s3c2416
set _ENDIAN little
set _CPUTAPID 0x07926f0f
proc on_reset_init {} {
echo "event: reset-init"
}
jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 0x01 -irmask 0x0f -expected-id
$_CPUTAPID
set _TARGETNAME $_CHIPNAME.cpu
target create $_TARGETNAME arm926ejs -endian $_ENDIAN -chain-position
$_TARGETNAME -variant arm926ejs
$_TARGETNAME configure -work-area-phys 0x4000000 -work-area-size 0x2000
-work-area-backup 0
reset_config trst_and_srst
#adapter_nsrst_assert_width 2000
#adapter_nsrst_delay 2000
set _NANDNAME $_CHIPNAME.nand
nand device $_NANDNAME s3c2410 $_TARGETNAME
$_TARGETNAME configure -event reset-init {
on_reset_init
}
------------------------------------------
So I think what I had is a double problem: an unexpected reset and a
failed intended reset.
Really hope someone can help me.

I can't go back to yesterday - because I was a different person then.
