PROCESSOR-SDK-AM64X: Package manager does not work

Dear TI Engineers and Experts,

I set up the processor sdk for Linux on my AM64x Starter Kit.

https://software-dl.ti.com/processor-sdk-linux/esd/AM64X/08_02_00_23/exports/docs/devices/AM64X/index.html

I then tried its built-in package manager to install nano editor by running:

opkg install nano

It returned

Collected	errors:
*	opkg_prepare_url_for_install:	Couldn't	find	anything	to	satisfy	'nano'.

Then, I ran

opkg update

It returned

How do I correct it?
