Enable serial console in a production device

Product support balenaOS
1

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

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

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

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 in config.json opens a login prompt on the serial console?

Yes enabling developmentMode in config.json started login prompt. There is no need to do anything else.

Huge thanks!
