Original question:

OCTVO-3P-AM335X: Boot Time Optimization

PROCESSOR-SDK-AM437X: How to set quiet boot and lpj properly.

Part Number: PROCESSOR-SDK-AM437X

I was reading this thread:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1062032/octvo-3p-am335x-boot-time-optimization/3945829?tisearch=e2e-sitesearch&keymatch=boot%252520time#3945829

and also the presentation it referenced.  

It looks like if I set the optargs u-boot env variable to "quiet" that should work but it has no effect. 

Can I get some input about what u-boot env variable to set to make the quiet boot and lpj work?

Also, just wanted to mention that the presentation referenced "several" resources/tutorials on the web.  It would be nice if good ones were referenced, as I didn't find much helpful stuff.

Thanks

Howard

    OK I found the issue, the optargs was also set in uEnv.txt and it was over-riding the value set in uboot.env.  

    So that is settled.   Unfortunately really not much of a boot time improvement though.

    Also, related to Schuler's presentation, rather than searching for overly specific stuff just searching for reducing linux boot time did indeed yield a bunch of stuff.  Sorry bout that.
