CC2340, load firmware using UART

Other Parts Discussed in Thread: SYSCONFIG

After set DIO 21 to enter bootloader mode, we are trying the serial firmware update. However, CC2340 seems not responding to our UART commands. we also try to load the firmware using EVA board, don't work either. Would you please provide a sample code on OS side that can talk to CC2340 for firmware update? 

  • Hi,

    Thank you for reaching out.

    May I kindly ask you to specify how you set DIO21 as bootloader back door pin? Have you changes the default configuration for the UART pins? (note: both can be done using SysConfig)

    Best regards,
