Part Number: CC3301

I downloaded the rtos example code for CC3301 , but there is only spi driver in it, no sdio driver.

Anyway, I completed the sdio driver by referring to the Linux sdio driver. Now my question is:

1. Can the fw in cc33xx_thickmac_package_0_4_0_1.exe support sdio driver?

2. If it can't, can we use the fw in linux sdk to work with rtos sdio driver?

3. If the fw in linux sdk can't be used, can you provide a fw for rtos sdio driver?

This is the file I downloaded:

the thickmac 0.4.0.1 doesn’t contain sdio support (currently). SDIO support requires replacing the bus_spi implementation (in wifi_platform_cc33xx) with bus_sdio (which we are planning to add in the a futurel release) and creating sdio_adapt for your platform.

So, the cc3301 wifi fw in linux sdk can be used in rtos system, is it right?

No. You need the same (ThickMAC) FW.

You need to compile the wifi_platform_cc33xx library differently (to include bus_sdio instead of bus_spi) and then provide your implementation of sdio_adapt as part of the application (the reference has spi_adapt implementation).
