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