I have the same issue: installed the official vi for CM4 from the DietPi website. I see the start screen with the “Please hit ” message. However, two different USB-keyboards dont work. Neither LAN nor WLAN are connected, so I have no possibility to get access. Then tried the RPI234, which Michaing was recommending. Same result. Since the device has an eMMC mass storage, I cannot load the image via SD-card. I use the official Raspi Imager SW. When I switch back to the Raspi image, it works.
That’s cool! However, how do I modify this file without having access? Is there a way to add this to the image before flashing it, so the problem is fixed in the first place?
Hm, I am not sure I understand the idea. On one hand, I have the DietPi .img file. I load this onto the eMMC with the Raspberry Pi Imager sw. The flash process works fine and after rebooting, I see the start screen, as described in my first post. The problem: the device is totally unaccessible, since the lan i/f is not configured and the usb doesn’t work. So, my only option seems to be the modification of the .img file.
