I want to initialize the SDIO interface,

but there are no routines and methods for me to use it,

can you give me a program code to simply initialize and use the SDIO?

Hi,

Sorry for the above misinformation provided. The example which I have mentioned in earlier response is for internal purpose and have some issues.

Kindly find the below sequence of steps to initialize the SDIO.

i.  Add "platform_sdio.h" to your project.

ii. Use "platform_sdio_host_init" to initialize the SDIO.

iii. Add and define the functions related to "platform_sdio_host_init"  in your application to know if "SDIO init error" or "SDIO init successful".

Please do let me know if you're facing any errors by following above steps, I'm glad to assist you.

Thanks.

Hi,

The process to initialize the SDIO interface for CYW954907 is same as that of CYW43907.

Can you please try to include the "platform_sdio.h" and use "sdcard_test" snip example in WICED SDK to initialize the SDIO interface.

Thanks.

Hi,

It's an exception error occurred in debug mode. You have to use "platform_sdio_host_init()" to initialise the SDIO interface.

Can you please let me know if you've followed the steps which were mentioned in previous response and defined the functions related to "platform_sdio_host_init()".

Thanks.
