JTAG has no access to imx6dl sabresd ddr.

Hi chip expertise,

When I setup our customer board same schematic with imx6dl sabresd, I got below error.

This means, I have no access read/write the ddrs. Someone can give some debugging method.

load_image u-boot-0x27800000_imx6dl_20160410.bin 0x27800000
JTAG-DP STICKY ERROR
MEM_AP_CSW 0x428000e2, MEM_AP_TAR 0x21b001c
Failed to write memory at 0x021b001c
embedded:startup.tcl:21: Error:
in procedure 'imx6.cpu.0'
in procedure 'ocd_bouncer'
at file "embedded:startup.tcl", line 21

Thanks!

Wenming
