Wifi + Sha Use

[isaac-asdf]

I'm trying to use the wifi module and the Sha peripheral, but when initializing the wifi after the Sha is initialized I get an error message saying

message: Some(
        called `Result::unwrap()` on an `Err` value: WifiError(InternalError(EspErrInvalidArg)),
    ),

My code looks like the below. Is there something that prevents using both peripherals? Or did I configure something wrong?

#[entry]
fn main() -> ! {
    let peripherals = Peripherals::take();
    let mut system = peripherals.DPORT.split();
    let clocks = ClockControl::boot_defaults(system.clock_control).freeze();

    // Disable the RTC and TIMG watchdog timers
    let mut rtc = Rtc::new(peripherals.RTC_CNTL);
    let timer_group0 = TimerGroup::new(
        peripherals.TIMG0,
        &clocks,
        &mut system.peripheral_clock_control,
    );
    let mut wdt0 = timer_group0.wdt;
    let timer = TimerGroup::new(
        peripherals.TIMG1,
        &clocks,
        &mut system.peripheral_clock_control,
    )
    .timer0;
    rtc.rwdt.disable();
    wdt0.disable();
    println!("Hello world!");
    let _hasher = Sha::new(
        peripherals.SHA,
        ShaMode::SHA512,
        &mut system.peripheral_clock_control,
    );

    esp_wifi::initialize(
        timer,
        Rng::new(peripherals.RNG),
        system.radio_clock_control,
        &clocks,
    )
    .unwrap();

    loop {}
}

Seems like the problem is let clocks = ClockControl::boot_defaults(system.clock_control).freeze(); - the CPU should run at the highest frequency for WiFi

Yeah, sorry for the confusion there. The actual code is here, the above code was a copy/paste of one of my iterations of trying to fix the problem. When using the boot_defaults() I get a Wrong Clock Config error, the WifiError(InternalError(EspErrInvalidArg)) is what gets thrown when the clock control is set correctly. The other oddity is that if I move the wifi initialize above the Sha peripheral usage, the wifi gets initialized but I get a divide by zero error when the hasher is used

[isaac-asdf]

I found the issue was actually in another library I had included, so my error message I was getting was unclear and made it seem like it was related to the hasher. Wifi + Sha works with the other things figured out. I'll close this!

On what chip is this happening? In theory what could be the problem is that wpa_supplicant is using that peripheral (in C) and using it concurrently is causing problems.

Once we have https://github.com/esp-rs/esp-wifi/issues/158 we could find a way to share the peripheral but I don't think that doable currently

If we can identify all the peripherals used there it would probably be safer to take these peripheral in initialize to avoid such confusions

The ESP32, I have the devkit board. Currently only using theSha peripheral and the wifi
