Hello All,
I am Ashish Agarwal.
Currently i am working on the MPC8536DS Freescale Development system evaluation
and the Uboot development for a customized board.
-------------------------------------------------------
Problem 1 : DDR Force setting
-------------------------------------------------------
when i try to force setting of DDR parameter over 8536DS board through the
#define CONFIG_SPD_EEPROM -> #undef CONFIG_SPD_EEPROM
#define CONFIG_DDR_SPD -> #undef CONFIG_DDR_SPD
the compile giver me error about "CONFIG_SPD_EEPROM is required" as this is
written at the bottom place of include/configs/MPC8536ds.h file
becuase we want to set forcly DDR parameters so I commented these lines too
====================================================
#ifndef CONFIG_SPD_EEPROM
#error ("CONFIG_SPD_EEPROM is required") #endif
====================================================
DDR Force parameter were set as they were set when i complied the source with
SPD setting. [Dumped from the Uboot].
They have to work for Force DDR setting too ;) but they are not working.
I was able to compile the souce and dowloading of uboot to the FLASH. but
ubootis stuck in between.
I stuck somewhere arround
"realocate_code" the next step of u-boot print statements where i am reaching
upto is
"Now Running in RAM- U-Boot at: %0x ".
and as i am not able to debugg u-boot via the CW it is paining me to get rid
out of this all stuff.
[UBoot Debug for the MPC8536DS is not rleased yet they might be supported in
8.8.3 version of CW :( ]
though i had done DDR parameter work for the VxWorks OS DDR Parameter setting
[so i now how to calculate those]
--> is it the source problem ??
The DDR parameter settings via "phys_size_t fixed_sdram(void)" function.
or it is the other issue ??
is i am missing something.

Any help or comments are highly appreciable.
