Install fail? #16

Closed doc-aka-rich closed 3 years ago

Funky ... As best I could, followed install, and after completing [& rebooting] slowly paints over the UCTRONICS logo and does nothing else. I attached a photo of the UCTRONICS logo being painted over. Once the logo is all BLACK, it just sits. The Pi seems hung by the driver, and won't accept SSH connection. Does this product work, is there something wrong with installing it on raspiOS, or did I do something wrong????

Here's my sys:

pi@raspberrypi:~/UCTRONICS_HSLCD35/Raspbian $ cat /proc/cpuinfo | grep Model Model : Raspberry Pi 3 Model B Plus Rev 1.3

pi@raspberrypi:~/UCTRONICS_HSLCD35/Raspbian $ cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=raspbian ID_LIKE=debian HOME_URL="http://www.raspbian.org/" SUPPORT_URL="http://www.raspbian.org/RaspbianForums" BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

Here's my install ... following the guide as best as I can:

It is working and can close this issue.

I initially tried loading github.com/UCTRONICS/UCTRONICS_HSLCD35, and it failed I then tried loading github.com/UCTRONICS/UCTRONICS_LCD35_RPI, and it failed I retried loading github.com/UCTRONICS/UCTRONICS_HSLCD35 ... and it worked.

The difference between the first attempt that failed and the 3rd attempt with the same drivers that succeeded is that I initially didn't connect the UCTRONICS LCD35 display until AFTER the drivers were loaded (at the reboot after driver loading).

For the retry I simply connected the UCTRONICS LCD35 at the start, through loading the OS, Pi configuration, and UCTRONICS driver install.

Whether the installer checks whether the hardware is present at some point during driver installation may or may not be the cause of the initial failure, but as long as it works I can live without knowing for sure.
