I changed the fleet configuration variables according to the documentation https://www.balena.io/blog/updating-config-txt-remotely/ , by adding new environment variables like RESIN_HOST_CONFIG_init_uart_clock 64000000, and the log displayed on the balena cloud UI indicates successful editing of the config.txt. However, after rebooting, I used balena ssh to ssh into the host OS and I find that the /resin-boot/config.txt has not been changed.
Also, it seems that the configurations I added have not been registered. Please assist. Thank you.
Supervisor Version: 9.15.0
Host OS version: balenaOS 2.36.0+rev2 (development)
