when we are setting boot target as m7 that same time when m7 booting that time i want to print m7 bootloader is up string in UART serial port prompt. how to do this can you please help me to complete this task
I could understand your requirement, the code you mentioned is relatively old and simple, for M core bootloader, I could suggest directly using bootloader project from GoldVIP, while the UART is by default supported.
