Hi Wolfgang,
Thanks for your reply.
Actually I am using a Freescale bsp that uses the u-boot-1.1.6 with some
patches
that modifies the bootloader for the freescale mpc8323erdb platform. This
platform uses the mpc8323erdb.c source which has the int fixed_sdram(void)
function on it to set the fixed ram to 64Mbytes.
I was thinking to include the get_ram_size() function on that source to
recognize automatticaly the ram size. Do you know if it is possible?
I am affraid to change the bootloader version to the latest one and get the
patches missed so I could not have my system working anymore.
Thanks and best regards
Ethan

It seems your port does not initialize the RAM correctly. The
recommended approach is to use get_ram_size() to automatically adjust
to the actual RAM memory size on the system.
Note that U-Boot 1.1.6 is more than 4.5 years old. An update to the
recent version is *strongly* recommended.
Best regards,
Wolfgang Denk
