Hi, BRCM experts,

I am now trying port Wiced-3.1.1 on my STM32F407 board with BCM43341, by adding my own WICED-SDK-3.1.1/platforms/MY43341/platform.c, and would like use USART1 as stdio port, but looks like it is not works. I tracked the code, it trapped into wiced_init() and never turns back. But if I use USART6 as stdio port, it works fine, my app runs without any problem. Any suggestion?

Thanks!

Hi, jone,

I referenced to ./BCM943362WCD6/platform.c, and modified mine, it works now.

Thanks!

According your platform files.

There are missing configuration ISR and DMA ISR for usart1!

There are some EVB is used STM32F4x7 all is work well for usart1!

Hi wolfman​ and jone

Can you just elaborate on the settings required on UART1 so as to work as STDIO using STM32f4 Discovery board.

I cannot use UART6(Port G) as there are no pinouts on the discovery board. I tried using UART2 and it works well. But I want it to work on UART1.

Kindly give hint on the appropriate settings for platform.c

Thanks in advance.

Which pin you used as USART1 ?

if used PA9/PA10 as tx/rx USART1 , you should do some H/W modified on the trace PA9/PA10 ! Otherwise the USART1 could not output any thing!

remove the 4.7uF capacitor on the trace PA9!
