Hello,  
I am using a CTI photon nano board with a Jetson Nano. I would like to enable serial console in a **production** image. I have tried using  
Using balenaOS 4.0.9 with 4.9.299-l4t-r32.7.3  
Supervisor version: 14.12.1

```auto
mount -o remount,rw /
systemctl enable serial-getty@serial0.service

```

Also put 'console=ttyS0,115200n8 ’ to enable in boot loader.

```auto
DEFAULT primary
TIMEOUT 10
MENU TITLE Boot Options
LABEL primary
      MENU LABEL primary boot/Image
      LINUX /boot/Image
      FDT default
     APPEND ${cbootargs} console=ttyS0,115200n8 ${resin_kernel_root} ro rootwait gasket.dma_bit_mask=32 pcie_aspm=off l4tver=32.7.3 ${os_cmdline} sdhci_tegra.en_boot_part_access=1

```

But still it doesn’t seem to be enabled. Any idea to make this work?

Thanks in advance.

Hi @berkayg, can you please check if enabling [developmentMode](https://docs.balena.io/reference/OS/configuration/#developmentmode) in config.json opens a login prompt on the serial console?

Yes enabling [developmentMode](https://docs.balena.io/reference/OS/configuration/#developmentmode) in config.json started login prompt. There is no need to do anything else.

Huge thanks!
