About L4t R28.2 support TX2

Dear Sir,

We planned to go directly from TX1 to Nano/Xavier EX, skip the TX2.
However our US customer would like to use TX2 with R28.2 which we already release to them and verified,
there will be a lot of effort if we upgrade the R28.2 to R28.3.2
because it’s not only L4T upgrade but also lots of tests need to go again for verification.

Could you give any assistance?

Yours Sincerely,

The effort should be ok since it stays in K4.4. You may check release notes first:

Upgrading to r32 requires more effort since kernel is also upgraded from 4.4 to 4.9.
