[U-Boot] Understanding a BDI U-boot issue

[Charles Krinke]

I have inherited a MPC8323ERDB project and when I connect my BDI to it, I
get to this point when the target is turned on.

CPU:   e300c2, MPC8323E, Rev: 1.1 at 333.333 MHz, CSB: 133.333 MHz
Econolite Control Products ASC/4I2C:   ready
DRAM:  64 MB
FLASH: 16 MB

With the BDI, when I issue its "go" command, I dont see anything else come
out  on the serial port.

I wonder if anyone might help me understand what sort of things might cause
this despicable situation.

Try "re ru".  If this makes it work, the BDI is probably doing
initialization that puts the board in a state that U-Boot isn't expecting.

   "GO" is not the right command here. If you have the u-boot
image already on the flash you would issue a boot, but you
have to have your config setup properly as well, in a way
that, it won't interface with what u-boot expects while still
making sure some stuff is taken care, e.g. watchdog is turned
of etc.

   This might be somewhat off topic here. If you need more info
contact me directly if you like or contact whoever sold
the BDO to you for support.
