Hi,

Can someone please share BDI3000 configuration file suitable for u-boot debugging on 460EX evaluation board (Canyonlands). I use the following file, which doesn't work

[TARGET]

JTAGCLOCK   1                   ;use 16 MHz JTAG clock
CPUTYPE     440                 ;the used target CPU type
WAKEUP      500                 ;wakeup time after reset
BREAKMODE   HARD                ;SOFT or HARD, HARD uses PPC hardware

breakpoint
STEPMODE HWBP ;JTAG or HWBP, HWBP uses one or two
hardware breakpoints
;MMU XLAT ;MMU support enabled
;PTBASE 0x000000f0 ;pointer to the page table pointers

[HOST]
IP 10.0.0.10
PROMPT 460EX>

[REGS]

IDCR1   0x010   0x011   ;MCIF0_CFGADDR  and MCIF0_CFGDATA
IDCR2   0x012   0x013   ;EBC0_CFGADDR   and EBC0_CFGDATA
IDCR3   0x014   0x015   ;EBM0_CFGADDR   and EBM0_CFGDATA
IDCR4   0x016   0x017   ;PPM0_CFGADDR   and PPM0_CFGDATA
IDCR5   0x00C   0x00D   ;CPR0_CFGADDR   and CPR0_CFGDATA
IDCR6   0x00E   0x00F   ;SDR0_CFGADDR   and SDR0_CFGDATA
PMM1    0x40000         ;Peripheral (base addr 4_0000_0000)
PMM2    0xC0000         ;PCI        (base addr C_0000_0000)
FILE    $reg460ex.def

I get the following errors:

460EX>reset
- TARGET: processing user reset request
- TARGET: resetting target passed

I had a feeling that my Canyonlands is broken, but maybe I'm doing something dumb.
BTW, I can program u-boot on NOR using this BDI3000 and different configuration
file.

Thanks a lot.

Felix.
