Hi all,
I have problems with the Bringup of a custom MPC8280 board and I assume that SDRAM could be the reason. When performing memory tests on the complete SDRAM with the test routines included with u-boot 0.4.5, everything is working fine. Also, u-boot is running without problems. But when booting a (known to work) linux kernel (2.4.18, MontaVista 3.0), I get exceptions after decompressing the kernel (alignment, 0x600) and when executing the initial scripts (program, 0x700). So I would like to perform more sophisticated SDRAM tests with u-boot, including burst tests. Is there anybody who has done this before? Any hints are appreciated.
Best regards
Thomas Schäfer
