Hi,
I'm trying to openocd working with a board that has an i.MX6UL processor. I've
put together a configuration file:
# ______________________________________________________________________ i.MX6UL
if { [info exists CHIPNAME] } {
set _CHIPNAME $CHIPNAME
} else {
set _CHIPNAME imx6
}
if { [info exists ENDIAN] } {
set _ENDIAN $ENDIAN
} else {
set _ENDIAN little
}
# CoreSight Debug Access Port
if { [info exists DAP_TAPID ] } {
set _DAP_TAPID $DAP_TAPID
} else {
set _DAP_TAPID 0x5ba00477
}
jtag newtap $_CHIPNAME dap -irlen 4 -ircapture 0x01 -irmask 0x0f -expected-id
$_DAP_TAPID
# SDMA / no IDCODE
jtag newtap $_CHIPNAME sdma -irlen 4 -ircapture 0x00 -irmask 0x0f
# System JTAG Controller
if { [info exists SJC_TAPID ] } {
set _SJC_TAPID $SJC_TAPID
} else {
set _SJC_TAPID 0x1891d01d
}
jtag newtap $_CHIPNAME sjc -irlen 5 -ircapture 0x01 -irmask 0x1f -expected-id
$_SJC_TAPID
# GDB target: Cortex-A, using DAP
set _TARGETNAME $_CHIPNAME.cpu
target create $_TARGETNAME cortex_a -endian $_ENDIAN -chain-position
$_CHIPNAME.dap -dbgbase 0x02130000
# some TCK cycles are required to activate the DEBUG power domain
jtag configure $_CHIPNAME.sjc -event post-reset "runtest 100"
# ______________________________________________________________________________
transport select jtag
reset_config none
adapter_khz 32

It examines the target using v0.9.0 from Ubuntu Repositories

Looking at the console the board carries on booting so the CPU hasn't been
halted. I then have to power cycle the JTAG debugger as it stays in this state.
It I turn on debug I get the following for examine targets:
