I have a beaglebone with Debian Os. I have created 2 partitions. The first partition is a boot partition while another partition contains a Debian Image. I am using uboot as a bootloader.
First Partition consists of the following files:-
- uEnv.txt
- boot/ ( Directory with kernel, dtb and other stuff to load the OS )
Second Partition:-
- Debian OS Image
My uEnv.txt Script:- Logs at Boot:

I am facing a scenario When I add; \this before my run loadall and other commands in the uEnv script it is working properly and booting me to partition 2 But it is not loading my UART port. ( Refer log 1 )But When I remove
; \from the uEnv.txt uboot is trying to boot me from the first partition and as I don't have OS on the first partition it is failing. My UART Port are loading properly ( Refer log 2 )Question:
How can I boot from partition and load my uart port? what am I missing?
