Hi.
I am trying to verify the external flash interfaced to the BCM943341 module (WICED 3.5.2).
Here is my pin configuration:
Module Pin 9 is SPI_MOSI
Module Pin 10 is SPI_MISO
Module Pin 11 is SCLK
Module Pin 12 is Chip Select
I have repurposed test/diagnostics/spi to read the JEDEC id. I also probed using the logic analyzer and I don't see SCLK out of pin 9.
I am thinking I am have messed up my SPI platform definitions. Please pass on any test application, debug, and platform files.
Thanks!
Regards,
Manish
This is in my platform.h header file:
/* SPI flash is present */
#define WICED_PLATFORM_INCLUDES_SPI_FLASH
/* SPI Flash. Implemented by Inventek Systems ... */
#ifdef WICED_PLATFORM_INCLUDES_SPI_FLASH
//#pragma message "SPI Flash included in platform"
//#define WICED_PLATFORM_INCLUDES_SPI_FLASH
#define WICED_SPI_FLASH_CS ( WICED_GPIO_8 ) //( WICED_GPIO_21 )
#define WICED_SPI_FLASH_MOSI ( WICED_GPIO_5 ) //( WICED_GPIO_18 )
#define WICED_SPI_FLASH_MISO ( WICED_GPIO_6 ) //( WICED_GPIO_17 )
#define WICED_SPI_FLASH_CLK ( WICED_GPIO_7 )//( WICED_GPIO_19 )
#endif
