I can't flash or interact with a CM4 (32gb emmc 8gb ram WiFi) I recently purchased. The activity light is flashing green rapidly and constantly, there is no pattern to the flashing. The device is not showing up on the PC. I do have rpiboot/usbboot installed & running. I've tried two IO boards (Waveshare Nano-C and Waveshare Dual Gigabit). Same results on both. Variety of USB cables and ports. The Dual-Gb is sufficiently powered, can't say the same for the straight shot USB Nano-C on my PC USB ports. Google searching the continuous flash doesn't offer much in the way of help. I have plenty of experience with RPi and microcontrollers but none with the Pi CMs. Might it be the CM4 itself? Can anyone offer any direction/solutions?
Thanks
Thanks
