The radar doesn’t go into bootloader mode no matter what i do. I tried using 3.3v to the boot and and Rst ports and it stilll didn’t work. STM32Cubeprogrammer still won’t connect to it.
How is it being powered? What are the LEDs doing? Has anything been soldered?
i am using a usb-c to my pc. the power LED is on . nothing has been soldered onto it. i used a volmeter between gnd and rst and boot and 3.3v and they were both pulling 3.3 v
To be clear, you held BOOT, then pressed RESET, and continued to hold BOOT for a couple seconds while it powered up? Flashing Firmware to the XM125 - SparkFun Qwiic Pulsed Coherent Radar Sensor Breakout - Acconeer XM125 Hookup Guide
The other thing is to ensure you don’t have the auto-select baud rate in STMcube…set it manually to 115200
