AM2434: Multiple QSPI Flash

Part Number: AM2434
Other Parts Discussed in Thread: SYSCONFIG

Does AM2434 and TI SDK(sysconfig) support multiple OSPI interfaces?

Customer considering using two QSPI Flash at the same time.

 

Does AM2434 support such use cases?

  • Hi ,

    Does AM2434 and TI SDK(sysconfig) support multiple OSPI interfaces?

    As per the intended design the AM2434 can support multiple interfaces using chip select pins. Although it is expected that even though it is possible to connect 2 QSPI, the advice would be to try to do the same flash parts. This is because, even though the vendor specific changes are possible to disrupt the flow and seamline flow of software. Also, this can make software very difficult to handle.

    The driver as well as the SDK should support to work with the same. Although, it has to be done at application level with same flash parts.

    We will still analyze again to understand if there are any ways to do it in the SDK at library level.

  • Hi Aakash,

    Customer tried to add 2nd SPI Flash memory on the sysconfig gui tool, but  got an error like attached screenshot. Using sysconfig 1.14.

    Please let me know if there are any additional instruction.

  • Hi Aakash,

    Another option, when two different Flash ROMs are connected to the same SPI BUS and switched by external MUX, How should configure sysconfig settings?

     I think Sysconfig should usually assign one SPI Flash driver to one SPI Flash setting. Is t his option even possible?

  • Hi ,

    This is not supported by SYSCFG. This is because hardware only supports single set of config registers so the support by design is in a way where you can have same parts of flash connected to the device at different chip selects. Although we only support single memory map option at the current moment.
