Can you please help me get blinky example to work?

[mejobloggs]

Hello Slappy, may I have some help please? I am trying to learn

I flash blinky, but I see no light. See my cargo run output below

Also, is it normal I need to pull usb out, hold down bootloader button, and plug usb in again to flash? And if I wait too long I cant flash and have to pull usb out again. Is there easier way?

Thank you

You could also try the uart example and see if anything is landing on console. Your logs suggest the device flashed successfully. Perhaps your led is on a different pin? Can you link to the board you used? Were you able to flash in any of the

Here's the dev board I used:
https://www.amazon.com/gp/product/B0BJZCLFKH
As far as I know it's identical in function to the "official" wch dev board.

The procedure you give to flash the board sounds correct to me. Personally, I keep PB22 grounded and powercycle before each flashing, but that should be equivalent to your procedure. Have you tested your procedure on any of the code from the "official" repo? https://github.com/openwch/ch583

I have WeAct CH582F from https://www.aliexpress.com/item/1005004784988010.html

I found the WeAct blinky example:

https://github.com/WeActStudio/WeActStudio.WCH-BLE-Core/blob/master/Examples/CH582/template/src/Main.c

In board.h they have

void board_led_toggle(void)
{
    GPIOA_InverseBits(GPIO_Pin_8);
}

I use wchisp to flash https://github.com/WeActStudio/WeActStudio.WCH-BLE-Core/blob/master/Examples/CH582/template/obj/template.hex and now led blinking. Cool!
