Creating .bin file for WsUartFu.exe

[Anonymous]

Hi,

I'm trying to get the uart_firmware_upgrade example working.

I am able to:

1.) successfully flash board with uart_fimrware_upgrade hex

2.) convert hello_sensor hex to a bin using ihex2bin.exe (c:\ihex2bin.exe hello_sensor.hex hello_sensor.bin)

3.) run WsUartFu.exe (c:\WsUartFu.exe hello_sensor.bin COM1)

4.) get c:\WsUartFu: upgrade status Success

This would seem to indicate that the uart upgrade was successful. However, after this point my board (EMRF-20736S-BOB) no longer works and I need to reflash it with the uart_firmware_upgrade before it starts to respond again.

Is there something I'm doing wrong when creating my bin file? Or do I need to add a flag when building a project for Uart upgrade?

Any help is much appreciated!

thanks,

akbar

The SK creates the OTA (and uart) upgrade images for you. Have you tried using the *.ota.bin file from the build directory?
