Unable to connect to svn URL repository

[akshulg]

$ svn co svn://svn.openwrt.org/openwrt/trunk@38333
svn: E170013: Unable to connect to a repository at URL 'svn://svn.openwrt.org/openwrt/trunk'
svn: E670002: Unknown hostname 'svn.openwrt.org'

I have successfully installed svn on my ubuntu20.04 PC. But getting this issue. Is the URL down or changed?

Openwrt no longer uses SVN for version control; they use git now. The archive of the SVN repository is here: https://git.openwrt.org/?p=openwrt/svn-archive/archive.git;a=summary

BUT you should not be using this old version. According to the README.md it is now supported mainline. See this for up to date documentation: https://openwrt.org/toh/hilink/hlk-rm04?s[]=rm04

So now there is no need for patch? Is that what you are implying?
I am not able to find files like diag.sh when I am downloading the new repo. So how will I be able to patch files?

Didn't need to do anything extra, well, not really, other than patching the available flash, but that's easy to do.
