Freeze when loading project

[aliakseika]

Hello, when I try to load a project from the no_std template onto the device, esp just freezes for a moment, as in the screenshot and that’s it, no action happens. Tried it on esp32H2 and esp32C6.
Maybe there are some ideas on what can be done about this?

Sorry, what do you mean by "freezes"? That "Hello World" prints are not shown? Are those printed afterward?

[aliakseika]

No - these are the last lines after loading and this continues endlessly.
I apologize, perhaps I am not expressing myself clearly. The fact is that I am writing through Google translator

Which devkit are you using? Are you using the "USB" or "UART" port of the devkit? Make sure you use the "UART" one

[aliakseika]

if i use uart port then i get different error

[SergioGasquez]

Can you run it with debug logs: RUST_LOG=debug cargo run. Also, can you edit .cargo/config.toml to add --no-stub into the espflash command so its espflash flash --monitor --no-stub

[aliakseika]

it works, thanks 👍 )

Maybe it is possible to connect the device via a USB port, or is it planned in the future? since the debug only works through the USB port, and not the UART. But then the firmware does not work)

But then the firmware does not work

Firmware does work, but in the default example you are writing to UART, so if you connect to USB you dont receive it. Have a look at https://github.com/esp-rs/esp-hal/blob/main/examples/src/bin/usb_serial_jtag.rs
