    update cyw20819 without minidriver



             I want to update firmware to cyw20819 using hci uart.

             I have successfully upgrade cyw20819 with minidriver.hex and mainapp.hex, and  only cts and rst  are used. Now we have to try the way without minidriver.hex, but it failed after we sent reset command and the first write_ram command.

      Do we have to control the rts?

      How can we control the cts, rts and rst in order to upgrade firmware successfully with minidriver.hex

      What are the command serial, reset, write_ram and launch_main_app?
