Q) How to initialize SDIO in CYW943907AEVAL1F
A) First look at the pin setup on the “CYW943907AEVAL1F Evaluation Kit”
Link to: CYW943907AEVAL1F Evaluation Kit User Guide
Reference: Section: 4.6 Micro SD Connector/Slot
The CY4343W uses a 4-bit SDIO version 2.0 interface
Table 4-5.
Micro SD Connector signals ( CYW943907AEVAL1F Evaluation Kit)
1 SDIO_DATA_0 DAT0
2 SDIO_DATA_1 DAT1
3 SDIO_DATA_2 DAT2
4 SDIO_DATA_3 CD/DAT3
5 SDIO_CMD CMD
6 SDIO_CLK CLK
7 PWM_0 DETECT
Make connection from your: SDIO Module to the CYW943907AEVAL1F Evaluation Kit using Table 4-5
Code:
Add in your Plateform.c file -- Configure SDIO pins -
Cut and Past below:
/* Wi-Fi SDIO bus pins. Used by WICED/platform/STM32F2xx/WWD/wwd_SDIO.c */
const platform_gpio_t wifi_sdio_pins[] =
{
[WWD_PIN_SDIO_OOB_IRQ] = { GPIOD, 12 },
[WWD_PIN_SDIO_CLK] = { GPIOC, 12 },
[WWD_PIN_SDIO_CMD] = { GPIOD, 2 },
[WWD_PIN_SDIO_D0] = { GPIOC, 8 },
[WWD_PIN_SDIO_D1] = { GPIOC, 9 },
[WWD_PIN_SDIO_D2] = { GPIOC, 10 },
[WWD_PIN_SDIO_D3] = { GPIOC, 11 },
};
Note:
Don't forget to add wwd_SDIO.c to your project.
Init Call:
Init - is called on line 120 - in wwd_SDIO.c
wwd_result_t host_platform_bus_init( void )
Debug:
debug prints: SDIO communication failure
Example: in wwd_SDIO.c file
/* Check if there were any SDIO errors */
if ( ( SDIO->STA & ( SDIO_STA_DTIMEOUT | SDIO_STA_CTIMEOUT ) ) != 0 )
{
goto restart;
}
else if ( ( ( SDIO->STA & ( SDIO_STA_CCRCFAIL | SDIO_STA_DCRCFAIL | SDIO_STA_TXUNDERR | SDIO_STA_RXOVERR ) ) != 0 ) )
{
wiced_assert( "SDIO communication failure", 0 );
goto restart;
}
If you need additional debug:

hello:
I found our AEVAL1F really leaves SDIO interface in the board, but can't find a SDIO device memo.
we have a wwd_SDIO.c in the platform\mcu\bcm4390x , I think you can have a print or call from host_platform_bus_init in your application.

I've browsed through this file, but I can't find a.h file that calls it
For example, when I call the "host_platform_bus_init" function in "wwd_dio.C", I call the "host_platform_bus_init" function in another file with the same name
