Hello guys, I’m a completely noob at raspberry pi and I got my new uconsole 2weeks ago. I assembled everything up and put the cm5 lite in it. I burn the ubuntu image which provided by Rex into the sd card but the screen show nothing. I try update the bootloader but it gives me a red screen in my external screen. When I try booting my uconsole I can see these messages on the external screen. ![IMG_9565](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/3X/c/5/c5b57bd725f5c2ad3be290722367fff011772608.jpeg) ---

I have a cm4 but as far as im aware you cannot use the cm4 to cpi adapter board with a cm5 you either need a waveshare one or a HackerGadgets one. ---

Thx for your reply! I am afraid that it is not the reason because I found a video that use the original board with the cm5. But I will try the hackergadget broad after all the troubleshooting! ---

have you updated eeprom? > [@EEPROM config and the CM5 lite](https://forum.clockworkpi.com/t/eeprom-config-and-the-cm5-lite/19649): > > With the upcoming release of NVME capable adapter boards from @vileer & @lululvlv I have changed up the EEPROM config to be able to use them. If you have a CM5 lite and are having problems with the sd card booting or have already updated the config but plan on getting a NVMe board. You need to edit your EEPROM and your CM5 lite has to have updated firmware that was released after 2025-01-06. Check using vcgencmd version to update sudo rpi-eeprom-update sudo rpi-eeprom-config -e To edit the eep… ---

you need the eeprom config changes so the SD card slows down a bit, the default settings are too sensitive to noise and don’t work reliably that’s why it says SD card not detected ---

Thx man. I will try to do that. But I’m still not quite sure how to do that.Do I need a io broad? Because I always get a black screen and I cannot operate on the external screen? Could you provide more information please? ---

try your older and smaller sd cards, it’s more likely to boot on those, then when it boots follow the steps in eeprom config thread @white-round-square linked, that also has a link to a card that seems to work on the cm5 with default settings ---

yooo~I try that Teamgroup SD card and it work! but it can only power on when usb-c power connected. I cannot turn it on when I plug in my 18650 battery even usb-c power connected. Do you have any recommendations for 18650 batteries? Thx for your help!! ---

The most recommended type is probably the Samsung 18650 35E. ---
