The external flash of 4M and 8M is used on RT1021. Why do you need to use QSPI mode to burn the program on the burner before ordinary burning can be carried out through JLINK and keil?

Hi @StarMao159376 

I hope that you are doing great.

I am afraid that I did not completely understood your question. Could you provide me more details?  

Need to use QSPI mode to burn the program on the burner  sounds to me that you are saying the you need to setup the RT1021 programmer into QSPI mode or that you need to set the  RT1021 into QSPI  boot mode before flashing your application. You can flash the RT1021 without being in QSPI mode, in serial downloader mode for example,   however to see the application running on the RT1021  the QSPI mode is required.

Many thanks for your patience.

Diego.
