CAT25 SPI-EEPROM Read was not happening properly RRS feed

  • Question

  • Hi,

       I am working on CAT25M01 SPI-EEPROM interface.In this when I run my driver I am not able to read the first 1byte.I have set the SPI in mode 0,chip select 0,clk 600k. 

    I have a query about this operation like:

    1.How to set the Burst length and Bit count while transmitting and receiving data.For Suppose I am writing 128 bits.

    regards

    srikanth.

    You told us almost nothing that we can use to help you.

    1. Does your driver load?  How do you know?
    2. Does the code run that sets the SPI mode?  How do you know?
    3. What hardware are you using - what SOC?
    4. Do you have the datasheet for the SPI bus controller? - this will answer your question about burst length and bit count.
