Hi everyone! My name is Artem.

I'm trying create ROM bootloader and begin learn API, but I can't found control of reset API (hard and soft resets).
Could you tell me where to find this API? Thank you =)

Best regards!

I use nor_writer for write application in 0x80000000 NOR flash, next reset device.
PIns setup like: IBL NOR boot on image 0 (default) SW3 (off, off, on, off, on, on, on, on) SW5 (on, on, on, off, on, on, on, on).

in my terminal is endlessly written the phrasea "IBL: Booting from NOR".

but I want write "Hello from Boot".

my C code:

TSCL = 0;
platform_uart_init();
platform_uart_set_baudrate(115200);
platform_write_configure(PLATFORM_WRITE_ALL);
platform_write("Hello from Boot");

Is it necessary to configure spi to interact with memory?

What am I doing wrong?

Thank you
