[U-Boot] How to do a basic memory test test using BDI??

Hi, Can I write simple tests for the RAM on a PPC460 and execute it using the BDI debugger? If I don't have linux / u-boot up on my board, how can I test the RAM?

Except for most basic tests like writing and reading single cells in memory which can be done using the "mm" and "md" commands, the most reasonable approach is a two-pass sort of solution: in the first pass, bring up U-Boot at least to the extent that it boots from flash and has the serial console running.
