Linux/AM3358: Device tree in RAM inaccessible

Phill Ogden1
Prodigy 230 points
Part Number: AM3358


Tool/software: Linux

HI all,

I'm attempting to get a Linux v 4.1.15 build running on an AM3358 board with 1GB RAM. During Kernel boot, the device hangs when it attempts to unpack the device tree in RAM. I traced the source of the corruption to the function `early_paging_init()`. Once this function has returned, I am unable to access the Device Tree from Virtual RAM. The processor hangs, then reboots after ~10 seconds.

The same image runs on my v1.0 board with 512MB RAM, and to my best knowledge, I have updated the RAM settings in u-boot and device trees. u-boot successfully detects 1GiB Ram, and the mtest function returns no errors.

The only known difference between the RAM chips is the Row Address changed from 32 to 64, the rest of the settings remained identical. This change was reflected in the ddr_defs.h file of u-boot.

Has anyone encountered these issues? Or have any recommendations for continuing my investigation?

    Further information:

    If I force uboot to only recognise 512MB RAM then my kernel boots properly on the 1GB hardware.

    Hello Phill,

    Can you attach your U-Boot environments and complete kernel boot log when the U-Boot it forced to use 512M on 1G hardware?

    Best regards,
    Kemal

    Hi Kemal,

    Sorry for the late reply, I had some issues with my build machine.

    This is the log for the hardcoded 512GiB ram

    Seems the Jupiter kernel is not able to see the whole system memory. Force it to use 1G memory by appending mem=1G to bootargs in U-Boot.

    Hi Kemal,

    The 'mem=1G' does not change the boot behaviour. I believe there is an issue with configuring my high page address line in u-boot, so I am investigating there further.

    Did you  solve the issue - I have similar issues for am335x 512Mib (works) and 1Gib (fails with page faults when trying to load RAM disk) ?
