Hi
Anybody who has same problem, please advise it.
Our module is adapted and ready to mass production.
We got faced problem with BCM4390 SPIL N-04 module.
For easy duplication, we tested with snip.uart sample application, It also make problem.
Issues : Serial data loss and module reboot issue
- SDK 3.7.0
- Device : BCM4390(SPIL N-04 ) and BCM43362
- Issue :
In case using “wiced_init( ) , wiced_network_up”and Serial input data comes continuously, module
goes to reboot or serial input data loss.
If not using “wiced_init( ) , wiced_network_up” no serial input loss
If wifi is not used then serial data loss does not happen
- Test appication : snip.uart
While module is ready to receive, just send file(file size: 351000Bytes ) at the terminal
Added function:
#ifdef ADDED_FUNCTION
wiced_init( );
wiced_network_up( WICED_STA_INTERFACE, WICED_USE_EXTERNAL_DHCP_SERVER, NULL );
#define RX_BUFFER_SIZE 2048
#endif
- Test condition :
UART port = WICED_UART_1
GLOBAL_DEFINES := WICED_DISABLE_STDIO
file size= 351000Bytes, and ping from external device to module ( 1 packet / second )
===========================================================
- Test result#1
1. serial baudrate =115200
2. BCM43362 works fine in FreeRTOS and ThreadX. No Problem
3. BCM4390 makes problem
--------------------------------------------------------------------------------
OS ThreadX FreeRTOS
--------------------------------------------------------------------------------
Network-up | rebooting rebooting
No network-up| OK OK
--------------------------------------------------------------------------------
===========================================================
- Test result#2
1. Baudrate changed : 38400
2. BCM4390 makes problem
OS ThreadX FreeRTOS
Network-up Serial data loss(10K) Serial data loss(10K)
===========================================================
We tested every baudrate but it has same problem. Attached file is the serial data loss picture
Thanks

The BCM4390 is not a broad market device, so it is not supported here on the community. I would doubt that many of our community users even have experience with this device.
We have since asked solomon to support you regionally using our internal SFDC system.
