    How to erase the app or whole flash?

      Now I can download the app using chiploader repeatly,  It is obviously that when redownload the app,the IDE will build and erase then download the new app,but I don't know how to just erase the app,is there any ways to do so,such as use chiploader or the IDE?

          I don't think this is possible.  Please explain what you are hoping to accomplish by erasing the app only.

           

          Note that the programming process overwrites the app that is stored in EEPROM.  Items like the BD_ADDR can be preserved (talked about elsewhere on the forum), but selecting the app only to erase would leave the device in a state which everytime it reboots it would go into recovery mode (i.e. does not detect a valid image).

            thanks,it seems impossible to just erase the app,Besides,can we erase the whole flash using the official tool?

            we met problem when using the TMC, we connect the TTL to HCI UART which used for sending test command,however,the sequence of which power on  influence the test result.when we use the empty device which never download the app and just run in TMC,if we first power on the  HCI UART connected to TTL,the device can only act reset command and didn't have response to  receiver or transmitter test ,while if we power on the device first then connect the TTL,the device can complete the all test.Strangely,if the device has download  the app,there's no effect on the sequence of power on.
