Part Number: WL1835MODCOM8B


Hi ,

We are planning to procure WL1835MODCOM8B for prototyping one of our products. Can I get the specification for WLAN_SDIO protocol between the HOST and the WLAN chip ?

Can this be downloaded from the TI website ? The HOST is running a proprietary, the necessary specifications are required for writing the custom WLAN driver for this Chip.

Thanks,

Murali

    Hi,

    Wilink8 is using a standard 4 bit sdio inerface for wlan together with two gpio pins.

    wlan_enable, and wlan_irq (for out of band sdio interrupt).

    The drivers are using the sdandard sdio interface in the linux kernel.

    Please check the following document as well:

    Best Regards,

    Hi Eyal ,

    Thank you very much for the support.

    I think I asked the question wrongly. I'm looking for details on what goes over the SDIO bus between the host and the chip.

    As I understand the interface between the host and the chip is SDIO and that the host send various commands over the SDIO interface to the firmware in the chip for it's needs like - scanning , Associating , status etc ..

    I'm looking for specifications or documentation for the firmware that reside in the chip. Some kind of interface control document which speaks about how/what to talk to the firmware on the chip.
    To be precise - the document which could be used to understand each methods of the struct wlcore_ops of the wlcore.h in wlink Linux driver provide by TI.

    Thanks,
    Murali
