Ravi, If you already have BDI2000, why don't you single step on it?

Hi All,
We have a custom target board based on PPC-EP405. We just got the=20
board from the hardware team .I connected the board to BDI200 andpowered=20
it on.=20 The control came to the resetvec address which is 0xfffffffc. I was
able=20
to read and write to flash. So I erased the flash and burnt the
bootloader=20
into flash from 0xfffc0000. I verified that the instruction at 0xfffffffc is 4bfc2104 whicis
actually=20
a branch to 0xfffc2100. Also a memory dump of 0xfffc2100 shows the
correct=20
code. This proved that the uboot bootloader was burnt properly. Now when I reset the board the control never reaches 0xfffc2100 i.e
for=20
some reason the code at the resetvec is not getting executed. Any help
or=20
pointers to resolve this is greatly appreciated. Thanks, Ravishankar Govindarao RFL Electronics Inc. E-mail : Ravi.Rao@rflelect.com Voice: 973.334.3100 Ext. 233 Fax: 973.334.3863 =20
