Another option (which we strongly recommend) would be for your customer to simply switch the product design to SPI, which is much easier integrate and set up between the AM243x and BP CC33x1. We also have guides for this to walk your customer through the process. If your customer's only option is to use SDIO but is willing to use a different host to talk to the BP CC33x1, we highly recommend your customer to use a Linux MPU host. Unfortunately, we currently cannot provide additional assistance (such as providing an SDIO example with the AM243x and BP CC33x1) without knowing more about your customer and your customer's goals.https://e2echina.ti.com/support/wireless-connectivity/wifi/f/wi-fi-forum/1054095/am2434-how-to-set-the-4-bit-mode-and-1-bit-mode-of-sdio-for-am2434-development-board-bp3351-module/3805192Fri, 06 Feb 2026 08:35:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:8dea0990-1650-4bdf-850a-d5784f844319Lydiafrom top to bottomhttps://e2echina.ti.com/support/wireless-connectivity/wifi/f/wi-fi-forum/1054095/am2434-how-to-set-the-4-bit-mode-and-1-bit-mode-of-sdio-for-am2434-development-board-bp3351-module/3805183Fri, 06 Feb 2026 07:54:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:6fcb73e0-5400-410c-a46d-90049b8cb19eBill GatesCan you resend the picture?

You would need to create seperate files similar to the image: The files would also need to be added to the makefile of the example, so its compiled. Additionally, do make sure the MMCSD instance in that is opened in the default MCU+SDK flow is closed or removed such that there is no error in opening this instance. The init API in itself does not need modification, rather the configurations that are being used in the init: Along with above configurations, the pinmux is also configured seperately like below: Please verify the correct pinmux configurations from the AM243 Datasheet as SDIO is not tested.
