Re: [U-Boot-Users] SDRAM "anti-problem"

In my experience the BDM connection is much, much slower than the RAM.

This is true.

If I load a kernel into the RAM with the BDM I have to get up and walk away, get a sandwitch, have a soda, etc...

Ummm... on most 8xx systems the BDI2000 needs about 7 seconds to load and burn 1 MB of image to flash. You must be really *fast* to fetch a sandwich in this time --- or you are using the wrong tools.

But If I transfer it in over TFTP it's nearly instantaneous.

Of course, this is faster, but then, on some flash chips the flah drivers in U-Boot are far from optimal.
