My uconsole had been working fine, yesterday I installed the RTL/SDR board option and after re-assembly it did work allowing me to configure all the appropriate files. However i did have the Antennas in the incorrect order so i disassembled in order to correct which antenna went where. when I reassembled it that time it now when powering on the display only reflects the backlight with NO characters on the display what so ever at any time. I am able to ssh into it however. So ive took it back apart and reseated the CM5 and tried again with the same results. Is there any log files or troubleshooting methods in order to get the display working once again? -Brian- ---

There are some little problems with the CM5. I have made a package to set everything up on the CM4 and 5 here. > [@HackerGadgets AIO Board Package](https://forum.clockworkpi.com/t/hackergadgets-aio-board-package/17875): > > I have been working on a package that sets up the HackerGadgets AIO Board. This package supports the RPi CM4/5. This package is designed for Debian if used on another distro YMMV. I wanted to make this package to take some of the headache of configuring everything if you so choose. To install the package in Debian sudo apt update && sudo apt --install-recommends install hackergadgets-uconsole-aio-board -y && sudo apt install meshtastic-mui -y to install everything If you would like to just ins… The problem you have is with the CM5 and meshtasticand the spi. The easiest route if you don’t want to install that package would be to `sudo apt install clockworkpi-blacklight` ---

OK i was just able to try the correct command and reboot my uconsole still with the same results, backlight but no characters or anything on the screen. I am able to still ssh into it however. I appreciate the suggestion but it appears that didnt fix the issue. -Brian- ---
