IWR6843ISK: Reset from USB/UART

Hardware Engineer
Prodigy 70 points
Part Number: IWR6843ISK

Is it possible to send a command through USB/UART to reset IWR6843ISK? We plan to deploy IWR6843ISK without MMWAVEBOOST and the only communication channel will be the USB/UART. I read https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/883668/ccs-iwr6843-soft-reset-dss but it's not clear if I can write to 0xAD to SOFTSYSRST over USB/UART.

    Hi Engineer,

    Yes, it can be done by writing  0xAD to  SOFTSYSRST 0xFFFFE11C via USB/UART in application level. The implementation is as follows:

    1.Add a new function called MmwDemo_CLIResetSystem in mmw_cli.c, 

    2.Use this function to modify the value of SOFTSYSRST register.

    3. Modify cliCfg.tableEntry in MmwDemo_CLIInit, adding a command such as  " resetSystem". 

    4.IWR6843ISK can be reset once you send the CLI command "resetSystem".

    Thank you
