Hi,
I am using arm-usb-ocd with openocd 0.2.0 to program arm11 based S3C6410 proc.
Configuring openocd is successful. Programming NOR flash and opening a successful debug session fail with the following errors on openocd console.
I would be greatful if anyone can provide me cues for the source of these errors:
Error: Data transfer failed. (-536873632)
Error: use ‘arm11 memwrite burst disable’ to disable fast burst mode
Error: auto_probe failed -4
Thanks 
P.S. In the programming script I tried arm11 memwrite burst disable but ended with same errors.
