finally. Its alive, ALIIIIIVEEE!!! 😳 😃 Thanks again soooo much @CursorBeat!!! And @Rex too for the EEPROM update, and @white-round-square for the initial troubleshooting! ![1000061209](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/8/8d35361713eb0f95c3cc91ef5471560417b63828.jpeg) ---

i had a similar problem with a new uconole after setting up i realize the adapter board would not click in when i push it down, had to tweak the metal tab a bit to get it to lock in place ---

yeah that was one of my issues indeed indeed. It was back alll the way, just could not get it fully clicked down initially. Had to fiddle a bit with the clips. Still think it would have worked, my issue turned out to be something different, but glad it was noticed before i took it on the (potentially bumpy) road 😉 Because would have become an issue later prob. ---

What if you already have the CM5 with EMMC storage. Can you still use the new adapter board for NVME instead of the EMMC or are you stuck just booting off the EMMC? ---

Yes, you can use the NVME to boot when you have EMMC. ---

Hi, I noticed that the board has a **“USB-C port for flashing: can be used to flash the eMMC version computer module.”** Does this mean I don’t need a developer board to flash the eMMC module? Also, is there any documentation on how to use this port for flashing? Thanks! ---

It was confirmed that you can use the USB-C flashing port to upload firmware without a developer board. > [@USB-C port for flashing: can be used to flash the eMMC version computer module](https://forum.clockworkpi.com/t/usb-c-port-for-flashing-can-be-used-to-flash-the-emmc-version-computer-module/20546): > > Hi, I noticed that the board has a “USB-C port for flashing: can be used to flash the eMMC version computer module.” Does this mean I don’t need a developer board to flash the eMMC module?

That is a addon board and not part of the stock uConsole. This thread has nothing to do with that adapter. So when you ask about the USB C port I assume you mean the stock USB C port on the device. You made no mention of the addon adapter board. ---

Hi Rex, my cm5 lite version with 16gb ram not able to boot up, i followed your instructions but no luck for the 16gb ram cm5, the cm5 is working fine on my waveshare nano b io board. And my cm5 8gb ram and 4 gb ram all are lite version are working on uconsole by your steps on eeprom config. please help if any changes can make the 16gb ram cm5 working? thanks! ---

did you manage to upgrade the eeprom? and edit the config file? thats really important. i’m using a 256GB high endurance card if it makes any difference. but prior to make those changes, the system boots rather unreliably. ---

Thanks, but I think I’m still missing something. I imaged the uConsole version of Trixie to a MicroSD and then edited the config.txt on the SD to have the vales shown above. I install it in my uConsole with my CM5Lite card using the HackerGadgets three board upgrade including a NVME 1TB SSD and it boots and let’s me go through all the configuration steps, then after a while, the screen goes black and it never comes back. ---

config.txt? it should be editing the eeprom. eeprom values are obtained by using “rpi-eeprom-config” to edit it, you use “rpi-eeprom-config -e” [Previous page](https://forum.clockworkpi.com/t/eeprom-config-and-the-cm5-lite/19649.md?page=3) [Next page](https://forum.clockworkpi.com/t/eeprom-config-and-the-cm5-lite/19649.md?page=5)
