DDR stress tester v1.0.2 with i.MX6DL error

I use Mx6DQSDL DDR3 Script Aid V0.08 and DDR stress tester v1.0.2 to calibrate i.MX6DL board DDR3.

MX6DL opened.


rom_write: reading HAB ack failed 0x00000000

ROM Write failed, addr: 0x021b001c

Write dcd failed.


If I just keep the first line of 0x021b001c access and comment out others, the test can go on, but still hang after setting DDR frequency as below.

MX6DL opened.

Re-open MX6x device.

Running DDR test..., press "ESC" key to exit.
