It looks like you have the correct macro - you would typically get that macro from the roach production files at: http://casper.berkeley.edu/svn/trunk/roach/production/test_software/roach_testing/macraigor_macros/loadram_rinit_auto.mac
The final command that the macro runs is 'exit', which closes OCD commander. So OCD commander closing unexpected is a feature not a bug! Once OCD commander quits you should start seeing activity on the serial port. Wait a while (more than 10s I think) until a character starts repeating (it looks like an S in hyperterminal). When this happens you are ready to transfer. Use XMODEM (not YMODEM) to xfer the u-boot.bin file. You'll find the latest file in: http://casper.berkeley.edu/svn/trunk/roach/sw/binaries/uboot/ You should have uboot running after the xmodem transfer completes.
