It seems you did so only partially.

So the commands you need are:
=> setenv serial# TQM860LDDBA3-P50.300 10226122 4
=> setenv ethaddr 00:D0:93:00:28:81

You can ignore this error.

Clearing/setting the SYSIE bit in the DER. The fast flash routines
used by the BDI2000 use system calls, so these should not be trapped.
This is probably no longer necessary with recent versions of the

Your BDI2000 config file probably includes a register definitions
file "reg860.def" or so. This should contain lines like these:
xer SPR 1
lr SPR 8
ctr SPR 9
dec SPR 22
pc SPR 26 ; is SRR0
srr1 SPR 27
eie SPR 80
eid SPR 81
der SPR 149
ictrl SPR 158
sprg0 SPR 272
sprg1 SPR 273
sprg2 SPR 274
sprg3 SPR 275
immr SPR 638
This is where the definition of DER is coming from...

Missing / broken / old version of reg860.def ?
