Please guide me how to configure Serial Rom boot loader for UART0. and flash the app code from Uniflash. I want to disable hardware invoke pin.

    Hello sowmya,

    So let me double confirm my understanding. You use ROM BSL with UART PA10 & PA11 and you disable the hardware invoke pin check; then in your app code, you add the software invoke code. Then you want to program this app code into one device through Uniflash. Do I understand correctly? And is this device a blank device (you never program before) or you have already program other code before. (If you use LaunchPad, it is not blank device)

    BR,
