Openocd configuration file for i.mx8qxp

[jing_xu1]

I want to use Openocd+JLink to debug IMX8QualMaxPlus MEK Board,  but there is no target/imx8qxp.cfg or board/nxp_mcimx8qxp-mek.cfg in /path/to/openocd/tcl/,so i made target/imx8qxp.cfg by myself refer to target/imx8m.cfg, however, i found that i can't send commands such as 'halt','reset' to the , maybe coresight base addresses of imx8m aren't apply to the i.mx8qxq?

My own imx8qxp.cfg:

if { [info exists CHIPNAME] } {
   set  _CHIPNAME $CHIPNAME
} else {
   set  _CHIPNAME imx8
}

if { [info exists CHIPCORES] } {
    set _cores $CHIPCORES
} else {
    set _cores 1
}

# CoreSight Debug Access Port
if { [info exists DAP_TAPID] } {
        set _DAP_TAPID $DAP_TAPID
} else {
        set _DAP_TAPID 0x1890201d
}

# the DAP tap
jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 0x01 -irmask 0x0f \
        -expected-id $_DAP_TAPID

dap create $_CHIPNAME.dap -chain-position $_CHIPNAME.cpu

set _TARGETNAME $_CHIPNAME.a53
set _CTINAME $_CHIPNAME.cti

set DBGBASE {0x80410000 0x80510000 0x80610000 0x80710000}
set CTIBASE {0x80420000 0x80520000 0x80620000 0x80720000}

for { set _core 0 } { $_core < $_cores } { incr _core } {

    cti create $_CTINAME.$_core -dap $_CHIPNAME.dap -ap-num 1 \
        -ctibase [lindex $CTIBASE $_core]

    set _command "target create $_TARGETNAME.$_core aarch64 -dap $_CHIPNAME.dap \
        -dbgbase [lindex $DBGBASE $_core] -cti $_CTINAME.$_core"

    if { $_core != 0 } {
        # non-boot core examination may fail
        set _command "$_command -defer-examine"
        set _smp_command "$_smp_command $_TARGETNAME.$_core"
    } else {
        set _smp_command "target smp $_TARGETNAME.$_core"
    }

    eval $_command
}

eval $_smp_command

# declare the auxiliary Cortex-M4 core on AP #4
# target create ${_CHIPNAME}.m4 cortex_m -dap ${_CHIPNAME}.dap -ap-num 4 \
               -defer-examine

# AHB-AP for direct access to soc bus
target create ${_CHIPNAME}.ahb mem_ap -dap ${_CHIPNAME}.dap -ap-num 0

# default target is A53 core 0
targets $_TARGETNAME.0

After i input 'dap info 1', these are output info:

Could you please provide the whole imx8qxp.cfg?

Thanks,
