Linux/66AK2H14: 66ak2h14

Part Number: 66AK2H14

Tool/software: Linux

Hello, Everybody

We have made our custom board with three 66ak2h14. We use onboard DDR3 memory chips for DDR3A and DDR3B. When the Linux boots the cmemk module says the MSMC area overlaps kernel.

This line is in the cmemk.conf file originally. If we comment out this line the cmemk succesfully loads, but all of the examples and test programs that use CMEM fail. The other memory allocation is successful.

In U-Boot the mem_reserve variable is set to 1536M.

But on the original K2HK evalboard this cmemk.conf works well.

What can be the problem, pls help me.

Regards

Gabor

    Hi,

    How is your ddr mapped among ddr3b?
    In general the momory that is connected to DDR3B is not used by linux, it is not mapped by MSMC and is not coherent with ARM. DDR3B is used by DSP only, see: e2e.ti.com/.../687454

    So you need to carefully inspect how you map the memory in your cmem dtsi and if this is consistent with the phisical mapping of the ddr among the two emifs (ddr3a & ddr3b).

    Best Regards,

    Hi,

    Thank you for your answer.

    The DDR3B is not used at this time on our board. The DDR3A_REMAP_EN pin is pulled up otherwise the DSP chip doesn't work at all. I didn't try to use the DDR3B, just the DDR3A only. Linux works well, but the

    CMEM. In the .dts files I couldn't find any reference in concernig with DDR3 memory mapping.

    Best regards,

    Gabor

    Could you share the complete bootlog? Also which Processor SDK Linux are you using?

    Hi Yordan,

    Here is my complete bootlog:

    This Linux runs on our custom board. My problem is that on the K2HK EVM I don't need to allow overlapping between kernel and MSMC but on our

    board I need. I had to allow the overlap in cmemk.conf (allowOverlap=1).

    This seemed to be good, the hyperlink test program (provided by TI) successfully runs. But our custom program badly crashes but on two EVMs runs successfully.

    best regards,

    Gabor

    Hi,

    Ok, I don't see anything wrong with the bootlog (cmem loads fine). How did you configure your k2hk-evm-cmem.dtsi file? Is it similar to the default one (the unmodified k2hk-evm-cmem.dtsi file, using the same memory regions, cma pools, cmem blocks)?

    Check the reserved-memory { dts node in keystone-k2hk-evm.dts file.

    Also can you explain what is your custom application doing? Can you compare the hyperlink example (provided by TI) & your custom app build configurations (linker.cmd & .cfg files) in terms of memory mapping?

    Best Regards,
    Yordan
