How to check available frequencies?

Hi,

I have some questions about your product. This thread is related to a previous discussion on ti forumhttps://e2e.ti.com/support/processors/f/791/p/769287/2846519#2846519

How to check from your part number which version of am3358 is integrated? There are some versions around, with different max frequency  600-800-1000.

One way is to check the part number of the integrated cpu but in your soc is not available.

Another way is to check the fuse register but it seems you don’t program them as reported here https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/am335x-osd335x-common.dtsi (dst used in debian) farther I found an other issue maybe. The above dts override the oppnitro using the same flags of oppturbo. It looks like that every osd3358 could get both the 800Mhz and the 1Ghz. Are you sure?

I have some bbbw with debian installed, the dts file declare the oppnitro by default without check (imho), I found a lot of instability at that frequency. Instead with the ti sdk, the 1Ghz is not supported because the fuse bits not programmed and the maximum clock is lowered to 800Mhz, the same bbbw are rock solid at this clock. My question is could there be some of your chips whose maximum frequency is not 1ghz? If yes How can I check?

I’m a little bit confused.

Thanks
