Unable to run examples/ieee802154_tx.rs on the nRF52840-DK

[potto216]

Has anyone sucessfully run examples/ieee802154_tx.rs on the nRF52840-DK? When I tried, it would hang on the line Ieee802154::set_tx_power(tx_power).unwrap(); or if I commented that out then on the next line Ieee802154::set_channel(channel).unwrap();. So for example the modified code in examples/ieee802154_tx.rs

fn main() {
    // Configure the radio
    let pan: u16 = 0xcafe;
    let addr_short: u16 = 0xdead;
    let addr_long: u64 = 0xdeaddad;
    let tx_power: i8 = 5;
    let channel: u8 = 11;
    writeln!(Console::writer(), "Starting...\n").unwrap();

    writeln!(Console::writer(), "dbg0-1\n").unwrap();
    Ieee802154::set_pan(pan);

    writeln!(Console::writer(), "dbg0-2\n").unwrap();
    Ieee802154::set_address_short(addr_short);

    writeln!(Console::writer(), "dbg0-3\n").unwrap();
    Ieee802154::set_address_long(addr_long);

    writeln!(Console::writer(), "dbg0-4\n").unwrap();
    //Ieee802154::set_tx_power(tx_power).unwrap(); //if this is not commented out it will hang here.

    writeln!(Console::writer(), "dbg0-5\n").unwrap();
    Ieee802154::set_channel(channel).unwrap();

    writeln!(Console::writer(), "dbg1\n").unwrap();

produces the output

tock$ Initialization complete. Entering main loop

It never printed "dbg1".

Also for some debug info I ran

As a check I was successfully able to run libtock-c/examples/tests/ieee802154/radio_tx/main.c and capture it's over the air packets with a wireless analyzer. Also its output was

Thanks for logging an issue @potto216! This very well may be a problem with the libtock-rs implementation as the libtock-rs 15.4 support is still fairly new. Before diving too far into debugging this, can you share which board file you used for the kernel?

[potto216]

Sure, is this the board file? target/nrf52840/thumbv7em-none-eabi/release/examples/ieee802154_tx.tab? This is how I created it:

cd libtock-rs/
tockloader erase-apps
make nrf52840 EXAMPLE=ieee802154_tx
tockloader install target/nrf52840/thumbv7em-none-eabi/release/examples/ieee802154_tx.tab
tockloader listen

Also, I used the same kernel (master branch) for both the libtock-c and libtock-rs tests.

[tyler-potyondy]

Sorry for the delay @potto216 cycling back to this!

The issue has to do with the kernel having two 15.4 interfaces (standard/phy) and the libtock-rs example/api attempting to incorrectly use this and resulting in an errorcode of no-support (leading to the unwrap() to terminate the app). I've made a PR that should fix these issue (#587).

(There's some more explanation on what's causing this mismatch in the PR if you're curious)

[potto216]

@tyler-potyondy thanks! And I'll also try out ieee802154_tx_raw, ieee802154_rx_raw, and ieee802154_rx_tx_raw in the next few days. Did you find the README or will it need to be created? If so, I can create a first draft. I assume it is for the capsule Ieee802154 = 0x30001 and would be added as the file 30001_ieee802154.md to the same directory the summary README https://github.com/tock/tock/blob/master/doc/syscalls/README.md is in.

[potto216]

@tyler-potyondy I tried your pr code in libtock-rs (tyler-potyondy:ieee802154-fixes) and I'm getting what looks like the same kind of problem with ieee802154_tx_raw where it hangs after Set long address to 0x000000000deaddad. I did not recompile the kernel and am using kernel_version: 2.3.0-dev. Do you see anything below that would suggest if I'm doing something wrong?
