ARM Support

Im struggling with basic wch-link on ch549 on Ubuntu. The problem is that wch-link doesnt want connect to stm32f0 via swd.

./wlink -vv  regs


15:22:51 [TRACE] (1) wlink::usb_device::libusb: [src/usb_device.rs:112] Device: 1a86:8012

15:22:51 [DEBUG] (1) nusb::platform::linux_usbfs::device: Closing device 0

Error: WCH-Link is connected, but is not in RV mode
That is happens with WCH-Link_APP_IAP_ARM.bin
In that case I have both LED are always ON.

If I use WCH-Link_APP_IAP_RV.bin

./wlink -vv regs

Error: Probe is not attached to an MCU, or debug is not enabled. (hint: use wchisp to enable debug)

I used all versions of WCH-Link 2.8, 2.11, 2.12m the same result.
So, Im wonder does it support ARM chips like stm32f0?
