Hello David
I try the mac file
http://casper.berkeley.edu/svn/trunk/roach/production/test_software/roach_testing/macraigor_macros/loadram_rinit_auto.mac
it works.
But the ROACH can't complete the whole uboot process.
The screen only shows the message as follows:
---------------------------------------------------------------------------------------------------
U-Boot 2008.10-svn2226 (Aug 7 2009 - 16:06:44)
CPU: AMCC PowerPC 440EPx Rev. A at 660 MHz (PLB=165, OPB=82, EBC=82 MHz)
No Security/Kasumi support
Bootstrap Option H - Boot ROM Location I2C (Addr 0x52)
32 kB I-Cache 32 kB D-Cache
Board: Roach
I2C: ready
DTT: 1 is 30 C
DRAM: (spd v1.2) 1 GB
---------------------------------------------------------------------------------------
What's happened?
Regards C-H Cheng

Hi.
Hello
I had erased/corrupted the flash memory during updating and I used OCD
commander to program PPC's uboot over USBWiggler. Of course I had the
macro(program.mac), too.
I follow the web page:
http://casper.berkeley.edu/wiki/ROACH_Bringup#PowerPC_U-Boot_Configuration
When I execute the OCD commander with macro, OCD commander show me a
lot of messages and the last line is "word 0x71000ffc = 0x4bfff004".
Then, OCD commander stop working....
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.
Cheers.
