Dears,

I found the problem.

The reference board (MPC8315ERDB) has 128MB DDR2. The new design has 256MB DDR2. I chanced the size macros in \incluce\configs\MPC8315E.h

#define CFG_DDR_SIZE 256 /* MB */ #define CFG_DDR_CS0_BNDS 0x0000000F

But I forgot change MMU configurations. Below the correct configuration.

#define CFG_IBAT0U (CFG_SDRAM_BASE | BATU_BL_256M| BATU_VS | BATU_VP)

Thanks,

Marcos Cunha Electrical Engineer

I am using u-boot 1.2.0 for mpc8315e processor with BDI2000 debugger in a new design based on MPC8315ERDB. Our board has a different DDR2 and Flash memory. The flash memory works fine. The problem could be DDR2.

U-Boot 1.2.0 is more than 2 years old.

You really should not use such ancient stuff for a new design.

You get the expected reply: please update, use current code and try again. If the problem still persists, please report back.
