[U-Boot-Users] 5272c3 Port (newbie)

[Robert Williams]

Hello,
 
I downloaded the latest u-boot from CVS today.  I've built the M5272C3
port successfully.  How do I burn this into flash?  
 
With an early version of ppcboot.  Someone, supplied a tarifa.elf file
which would initially load u-boot into ram.  U-boot would then load the
.bin file into flash.  
 
Does anyone know what the process is now?  I am using m68k-elf-tools. 
 
Cheers,
Robert

Hello Robert,

you can set CONFIG_MONITOR_IS_IN_RAM in the m5272c3.h config file.
Additionally you have to set TEXT_BASE to 0x20000 in board/m5272c3/config.mk.
Then you get a version which can be loaded to RAM at address 0x20000. You can
download it through a BDM interface or with you current boot loader (e.g. 
dbug)

You can use the RAM version to program the flashable version 
(CONFIG_MONITOR_IS_IN_RAM is not set and TEXT_BASE is set to 0xffe00000)
into the flash memory.

If something goes wrong while programming the image to flash, you need a BDM
interface to get your board running again!

Hope this helps!

Regards,

Josef
