Hi all, I’m trying to get the development image to work with the serial interface on a Raspberry Pi 3B+. I’m using the `/dev/serial0` interface for serial communication. On production images, this works great! I’ve no problem with using the serial interface stable on the production image. But for development, using a production image is not really the way to go. The problem with the development image is that it has some interference, I guess. Because after a few seconds of writing to the `/dev/serial0` interface, I get some input/output errors and it stops working, which is not the case on the production image. I’ve enabled uart on the Raspberry Pi via the balenaCloud dashboard, but I can’t seem to make it work stable on the development image. I’m developing via local mode, if that’s any useable information. I’m using the Raspberry Pi 3 development image with version 2.31.5+rev1. I’m happy to share some more details if necessary! ---

Anyone that can help me with this issue? It’s really hard to develop like this… ---

Hey @bversluijs, I believe the problem is that the .dev images write kernel logs to the to the serial console. I believe you can disable that by changing the `cmdline.txt` in `/mnt/boot/` on the running device. Find the console entry that refers to the serial0 device, and remove it, including the baud rate setting. It will look something like `console=serial0,115200` . Make sure the rest of the line remains the same, as errors in this configuration can stop the Raspberry Pi from booting. I have a feature request to make this opt out which you can follow here [https://github.com/balena-os/meta-balena/issues/1387](https://github.com/balena-os/meta-balena/issues/1387), but for now the best way is to manually change the cmdline.txt Let me know if that sorts things out for you. ---

ah, you also might need to remove `console=tty1` from cmdline.txt too. ---

How can I find this file? > I believe you can disable that by changing the `cmdline.txt` in `/mnt/boot/` If I ssh into the Host OS or into a container, it is not there.
