If all is configured correctly, you can just do:
BDI>rd esr
esr : 0x00000000 0
If not, but you know the SPR number, you can just do:
BDI>rdspr 0x3d4
SPR 980 : 0x00000000 0

The BDI came with a file called reg405gp.def. This file contains the
mappings from names to spr/dcr numbers. Make sure it is in your tftp
directory and then make sure you have something like:
[REGS]
IDCR1 0x010 0x011 ;MEMCFGADR and MEMCFGDATA
IDCR2 0x012 0x013 ;EBCCFGADR and EBCCFGDATA
IDCR3 0x014 0x015 ;KIAR and KIDR
FILE reg405gp.def
in your config file. BOOT your BDI and you should then be set.
