Hello List..

 i have a develop board based on mpc8247. It has no eeprom to restore
hareware configure word and i have to use default config word
0x00000000.
 my bdi config file:

[TARGET]
CPUTYPE     8270                ;the CPU type (603EV,750,8240,8260)
JTAGCLOCK   1                   ;use 16 MHz JTAG clock
BOOTADDR    0xfff00100          ;boot address used for start-up break
WORKSPACE   0x00000000          ;workspace in target RAM for fast
download and data cache flushing
BDIMODE     AGENT               ;the BDI working mode (LOADONLY |
AGENT | GATEWAY)

BAUDRATE    115200                ;baudrate for gateway mode or
virtual IO
BREAKMODE   SOFT                ;<AGENT> SOFT or HARD, HARD uses PPC
hardware breakpoint
VECTOR      CATCH               ;<AGENT> catch unhandled exceptions


DCACHE      NOFLUSH            ;<AGENT> data cache flushing (FLUSH |
NOFLUSH)
MEMBASE     0                   ;<AGENT> base of target memory
MEMSIZE     0x00004000          ;<AGENT> size of target memory, 64M


POOLBASE    0x00000000          ;<AGENT> base of host controlled target mem=
ory
POOLSIZE    0x00004000          ;<AGENT> size of host controlled
target memory

 When i connect BDI2000(bdiwind_cop, firmware 1.13, logic 1.02 ) to
the board, the following messages

are printed, then it have no response!

 When i set CPUTYPE to 8260, the following messages are printed continously=
:
