Linux/AM5728: QSPI flash read/write/erase performance numbers

Swapna yendrapalli

Part Number: AM5728

Tool/software: Linux

Hello,

 We are using SDK TI-SDK-4.0.0.4-kernel-4.9.28 and QSPI MX66L1G45G device for booting.

 Could you please advise

- If TI has any throughput measurements for read/write and erase operations on QSPI interface.

- Any optimizations suggested to improve the write/read/erase performance on linux kernel

Thanks,

Swapna

    Swapna,

    We haven't published any QSPI numbers for AM57x. I will record a request to do so, but they will only come out with a future version of the SDK.

    Similarly, I don't see any plans to make any improvements at this time.

    Swapna,

    I was able to find the below performance numbers:
    Uboot qspi: Read: 25MB/S and write: 0.7MB/S
    Kernel qspi with ubifs: Read 19MB/S and write: 0.3MB/S

    At this time, we feel we don't have plans to try to improve beyond this.

    I hope this is helpful to you.
