對「Work Todo: NXP ISP1761」的想法

  1. data transfer rate is very low on PXA270/ISP1761 use a default WinCE/Linux driver.
    currently I pending the work. if anyone want optimazation.
    1. not enable SOF Interrupt
    2. check Client Driver and PTD data transfer method and bandwidth. (using DMA to transfer is better)

  2. Hi. how are you?

    My name is LimChulHoo. do you remember me?

    I ported ISP1761 on my Linux PXA270 Board.

    It’s data transfer rate is about 47MB. I think, It’s very nice. thanks for your advice.

    I wish to make a request.

    I am porting Windows CE on my PXA board.

    but I havn’t ISP1761  Windows CE device driver.

    can you give me the ISP1761 device driver?

    I contect to NXP. but NXP did not supported to me. Because I don’t bought the ISP1761 chips from NXP.
