Rock960 Debug with Olimex and OpenOCD

I’m trying get debugging up and running on this board.
I have a SDCard breakout board and an olimex arm-usb-tiny with an olimex swd converter
I’m using openocd with this script

adapter speed 1000

set _CHIPNAME rk3399

set _ENDIAN little

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

cti create cti0 -dap $_CHIPNAME.dap -ap-num 6 -ctibase 0xfe438000

target create ${_TARGETNAME}0 aarch64 -dap $_CHIPNAME.dap \
    -coreid 0 -dbgbase 0xfe43000 -cti cti0 -gdb-port 3333

${_TARGETNAME}0 configure -event reset-assert-post "aarch64 dbginit"

targets ${_TARGETNAME}0 

and executing openocd as follows:

openocd -f tcl/interface/ftdi/olimex-arm-usb-tiny-h.cfg -f tcl/interface/ftdi/olimex-arm-jtag-swd.cfg -f tcl/target/rk3399.cfg

Is there something else I’m missing?

I have the same problem with a similar setup than @David_Cerdeira. I feel that is something related with the system reset. Any hint from anyone ?
