I am facing issue in loading uart port for Beaglebone Debian.
Following are my configurations:
I have a beaglebone with Debian OS. I have an sd card with 4 Partitions.
Partition 1 ( mmcblk0p1 ) contains following bootloader configurations:-
- /boot/dtbs/4.14.71-ti-r80/am335x-bonegreen-wireless.dtb
- /boot/vmlinuz-4.14.71-ti-r80
- /boot/uEnv.txt
- /boot/initrd.img-4.14.71-ti-r80
- /lib/firmware/BB-UART4-00A0.dtbo
- /lib/firmware/BB-UART1-00A0.dtbo
- /lib/firmware/BB-I2C2-00A0.dtbo
- /lib/firmware/AM335X-PRU-UIO-00A0.dtbo
- /lib/firmware/BB-BBGW-WL1835-00A0.dtbo
- /lib/firmware/BB-BONE-eMMC1-01-00A0.dtbo
- /lib/firmware/BB-ADC-00A0.dtbo
- /uEnv.txt
Partition 2 ( mmcblk0p2 ) contains the Debian OS.
Partition 3 ( mmcblk0p3 ) contains another Debian OS.
Partition 4 ( mmcblk0p4 ) decides from Which partition to boot?
/uEnv.txt from mmcblk0p1 reads from mmcblk0p4 and decides from which partition to boot.
This is my /uEnv.txt:

You are using the "uenvcmd" path, it's up to "YOU" to load the overlays.

Yes, I'm loading the Overlays. In my uEnv.txt I am running loadall which loads the /boot/uEnv.txt. What am I doing wrong here or what am I missing here?

Uh nope, your assumption is incorrect.
while loadall, loads the variables from /boot/uEnv.txt, the overlay path thru uboot is NOT enabled...
Why isn't it enabled? Well I did not write it for that path, because old uboot + doing Overlays = uboot hard faults..
So to repeat..
You are using the "uenvcmd" path, it's up to "YOU" to load the overlays in your uboot script.

Okay, I see your point.
Just for verification purpose, you are talking about check_uboot_overlays from the script right?
Also, How can I enable the overlay path through uboot?
Thank you

so let's look at your script, and what u-boot did

uenvcmd=\
run loadall; \
run findroot; \
echo Using root partition ${rootpart}; \
if run loadfdt; then \
echo Loaded ${fdtfile}; \
if run loadimage; then \
run mmcargs; \
bootz ${loadaddr} - ${fdtaddr}; \
fi; \
fi;
loadall=run loaduEnvtxt; run check_dtb; run check_uboot_overlays; run loadxrd;
"enable_uboot_overlays" is enabled.. Finally we load the initrd..
loadxrd=echo debug: [/boot/initrd.img-${uname_r}] ... ; load mmc 0:1
${rdaddr} /boot/initrd.img-${uname_r}; setenv rdsize ${filesize}
Set's root mmc..
loadfdt;
Loads the device tree:
loadfdt=echo debug: [/boot/dtbs/${uname_r}/${fdtfile}] ... ;load mmc
0:1 ${fdtaddr} /boot/dtbs/${uname_r}/${fdtfile}
loadimage
loadimage=echo debug: [/boot/vmlinuz-${uname_r}] ... ; load mmc 0:1
${loadaddr} /boot/vmlinuz-${uname_r}
mmcargs=setenv bootargs console=${console} ${optargs} ${cape_disable}
${cape_enable} root=${mmcroot} rootfstype=${mmcrootfstype} ${cmdline}
bootz ${loadaddr} - ${fdtaddr};
aka boot into linux..
Then we look at what u-boot did:

So your "run check_uboot_overlays;" did nothing...

/boot/uEnv.txt = (default) we take care of it..

Still, I am unable to understand How can I enable the overlays and load the UART Port.
What I did was I add these lines in my /uEnv.txt under uenvcmd:

What am I doing wrong here? How can I boot from partition2 or partition 3 while loading all the UART Port?

Wrong order, you placed my "reference example" before the you loaded

the main dtb. ( i also didn't expect you'd just copy it as is.. so
let's expand it more..)
```
if run loadfdt; then \
echo Loaded ${fdtfile}; \
setenv fdt_buffer 0x60000; \
echo Loaded ${fdtfile}; \
load mmc 0:1 ${rdaddr} /lib/firmware/BB-UART4-00A0.dtbo; \
fdt addr ${fdtaddr}; \
fdt resize ${fdt_buffer}; \
fdt apply ${rdaddr}; \
fdt resize ${fdt_buffer}; \
load mmc 0:1 ${rdaddr} /lib/firmware/BB-UART1-00A0.dtbo; \
fdt resize ${fdt_buffer}; \
fdt apply ${rdaddr}; \
fdt resize ${fdt_buffer}; \
fdt addr ${fdtaddr}; \
fdt resize ${fdt_buffer}; \
fdt apply ${rdaddr}; \
fdt resize ${fdt_buffer}; \
<and so on>
fdt resize ${fdt_buffer}; \
fdt apply ${rdaddr}; \
fdt resize ${fdt_buffer}; \
<and so on>
if run loadimage; then \
run mmcargs; \
bootz ${loadaddr} - ${fdtaddr}; \
fi; \
fi;
```
run mmcargs; \
bootz ${loadaddr} - ${fdtaddr}; \
fi; \
fi;
Does that now make sense?

When I add under if run loadfdt; then \ This is working properly
setenv fdt_buffer 0x60000; \
fatload mmc 0:1 ${rdaddr} /lib/firmware/BB-UART4-00A0.dtbo; \
fdt addr ${fdtaddr}; \ fdt resize ${fdt_buffer}; \
fdt apply ${rdaddr}; \
fdt resize ${fdt_buffer}; \
fatload mmc 0:1 ${rdaddr} /lib/firmware/BB-UART1-00A0.dtbo; \
But When I add anything under fatload mmc 0:1 ${rdaddr} /lib/firmware/BB-UART1-00A0.dtbo; \
Uboot starts booting in a different way.
