On core 1, that bootrom will "park" it waiting to be awaken.

On core 0, that bootrom I'll load 256bytes from the external spi flash and run whatever is loaded.

Those 256bytes should configure the spiflash interface and the xip block so that it matches the best performances of that flash device.

Do you have your code available online for us to review it?

Did you use one of our many examples or seeded your project with the template we provide ?

Hello, I am trying to control my servo motor with PWM On the raspberry pi pico, but cannot seem to get anywhere with the right pwm values, here is the documentation from my servo:
https://docs.rs-online.com/0e85/0900766b8123f8d7.pdf

and I have some code snippets, it is just modified example code, The problem I have is no matter what duty cycle values I pass in, I cannot get the full range of motion or set angles properly
let pwm = &mut pwm_slices.pwm0;
pwm.set_ph_correct();
pwm.set_div_int(20u8); // 50 hz
pwm.enable();

// Output channel B on PWM0 to the GPIO1 pin
let channel = &mut pwm.channel_b;
channel.output_to(pins.gpio1);

// Infinite loop, moving micro servo from one position to another.
// You may need to adjust the pulse width since several servos from
// different manufacturers respond differently.
loop {
    // move to 0°
    channel.set_duty(750);
    count_down.start(400.millis());
    let _ = nb::block!(count_down.wait());

    // 0° to 90°
    channel.set_duty(1500);
    count_down.start(400.millis());
    let _ = nb::block!(count_down.wait());

    channel.set_duty(2250);
    count_down.start(800.millis());
    let _ = nb::block!(count_down.wait());
}

}

I think the clock divider may need to be set to 2 or 3 instead of 20.

my thought process is that given a system clock of 12MHz/ 63535 counts of the pwm counter or whatever / 3 = ~61 Hz

Ah that right, I understood the question as a test binary running on the core, not as binary modelling the core :D

Thanks Mathias @mbrossard:matrix.org
