Hi,
I'm working with an ARM926ej-s and when I plug it and try to load for
first time openOCD crash like that :
Debug: 438 32773 ft2232.c:1312 ftdi_execute_scan(): FTDI device
buffer size reached, sending queued commands (first_unsent: 0xb9d7a0,
cmd: 0xba0db0)
Warn : 439 32777 core.c:745 jtag_check_value_inner(): Bad value
'00000245' captured during DR or IR scan:
Warn : 440 32777 core.c:746 jtag_check_value_inner(): check_value:
0x00000009
Warn : 441 32777 core.c:755 jtag_check_value_inner(): check_mask:

Error: 442 32778 arm7_9_common.c:2451 arm7_9_write_memory(): JTAG
error while reading cpsr
And saying that is a debug reason 6. But when I'm retry it's work.
In fact it's look like when we got a debug reason #6 it's because CPU is
not halted, so I made a patch that work great.
