While porting our software to SDK 3.7 for SSL/TLS with MQTT
Device : BCM94390WCD with SPIL module
Status:
UART is not working in SDK3.7.0
From the module view, UART TX is working, UART RX is not working.
Same code, different target to BCM943362, it is working
We tested with #ifndef BCM4390X_UART_SLOW_POLL_MODE definition for "platform_uart_receive_bytes"
It also does not work.
For simple duplication,
snip.uart-BCM943362WCD4-FreeRTOS-LwIP download run <== this works
snip.uart-BCM94390WCD2-FreeRTOS-LwIP download run <== this does not work.
