Not completely true. We have limited release thru source and CICD basic sanity for this platform.

Would prefer to rebrand no as " Limited/CICD "

This isn't a replacement variable, it's just a static config that changes content in source/linux/Overview/_Processor_SDK_Building_The_SDK.rst. Setting the string to Limited/CICD is the same as setting it to no.

@praneethbajjuri this is for SDK 11.2, right?

For AM335x & AM437x, we should leave most of the PRU pages here - there is no replacement PRU Academy for these devices.

The AM335x/AM437x PRU Soft UART (AKA software UART) was no longer supported as of SDK 9.1 (though support may have been dropped earlier), that should have been dropped from the docs years ago:
https://jira.itg.ti.com/browse/LCPD-37422

Please remove this page. I would prefer to also list the descope in the release notes, but I'm not sure how yall would handle a descope from years ago: https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/11_02_05_02/exports/docs/linux/Foundational_Components/PRU-ICSS/Linux_Drivers/pru-sw-uart.html

It is worth checking PRU Serial UART (aka hardware UART) to make sure it is still supported on kernel 6.12, I'm not sure if this got upstreamed or not.

For AM62x & AM64x the April 2026 release of PRU Academy did migrate over multiple pages that used to be hosted in the Linux SDK, so we can chat about updating SDK 12.0 docs to point to the new academy pages.
