K2E: DDR3 PHY rank margin testing



Hi,

 

in the MCSDK is there software that can be used to do DDR3 Rank Margin testing, i.e. set the PHY registers and run DDR error rate testing?

 

Thanks,

--Gunter

 

  • Hello Gunter,

    We do not have such test code as a part of MCSDK. We have DDR write/read test only in platform code and GEL file.

  • Hi,

    DDR3 Rank Margin testing : -

    For DDR3, In uBoot, we have only the following three commands for DDR testing. We do not have anything like Rank margin testing for DDR3.

    Usage:
    ddr test <start_addr in hex> <end_addr in hex> - test DDR from start address to end address
    ddr compare <start_addr in hex> <end_addr in hex> <size in hex> - compare DDR data of (size) bytes from start address to end address
    ddr ecc_err <addr in hex> <bit_err in hex> - generate bit errors in DDR data at <addr>, the command will read a 32-bit data from <add
    r>, and write (data ^ bit_err) back to <addr>
