if i download a code successfully, once the code is loaded. Next time if i try to download application, it fails? Every time i have to follow the below steps for programming.

What is the problem?

Hi AkJa_4647796 ,

Its not because your serial flash is corrupted.

Recovery procedure is recommended to have download process. So that the device will be in download mode.

So please do recovery procedure prior to download.

  • Press and hold the Recovery button
  • Press and release the Reset (SW2) button
  • Release recovery button

Also I would suggest you to add the HCI UART port in the make file

For example : test.Observer-CYBT_343026_EVAL download UART=COM23

Please also go through below KBAs for better understanding :
