Loading STUSB4500 NVM config into STUSB4500L chip doesn't allow expected PD contracts. I am running on STSW-STUSB002 V1.09. Will upgrade to V1.1.1 allow for proper config of STUSB4500L? Thank you.

I have the same issue but I am running STSW-STUSB002 v1.1.1. The NVM config for STUSB4500 will not work on the STUSB4500L.

Hello Mmade.1,

Thank for your answer.

Looks like customer support is quite poor at STmicro.

Mmmmh, wondering if TI's got good parts and useful GUI: customer support is fine at TI's.

Hello again Mmade.1,

Do you get a "SINK PARAMETERS" page on the V1.11 GUI, like on the V1.09 one?

I don't.

No way to program the 4500L chip, though.

I don't know if I missed something on the installation.

Please let me know.

Regards.

Matt.

PS: I believe register mapping has changed from 4500 to 4500L. Reason why NVM configs for 4500 don't work with 4500L...

[Mmade.11]

The documentation on the register mapping, especially for the NVM, is extremely poor. I had to go hunting through the ST code to understand how to program the NVM and then port that to Linux. Do you know of a way to identify the 4500 vs the 4500L part? The device id returns the same value for both parts.

[Mmade.11]

And to answer your first question, I do get the SINK PARAMETERS page on v1.11.

I don't know other way than to look at the writing on the chip case! I didn't even notice there was a "L" suffix when I got the chips.

I'm in big troubles, 4500 no "L" isn't avalaible at present time.

So you do get the "SINK PARAMETERS" page on V1.11. I don't know what's wrong with my Windows 10 installation.

And even when entering all PDOPs voltage, current, tolerances parameters by hand doesn't help?

I mean: still no way to have the 4500L comply to the same PDOs than 4500?

Thanks.

Regards.

We are in the same trouble boat. The ability to get parts is hurting our development as well.

Yes, I do get the "SINK PARAMETERS" page on v1.11. I took a screenshot and it is above.

Hello again,
Yes I do get the same window as far as NO STUSB4500L is connected.
Otherwise this NVM settings page is no more avalible.
I think this is because 4500L NVM mapping is not the same as 4500.
And actually, when the system "sees" a regular 4500 chip, the "NVM
settings" page doesn't disappear!

Thanks. And it doesn't work?

I mean not trying to import a whole NVM config, but entering ALL parameters one by one?

I am trying to find a software that appeared a few hours ago ON ST's site, written by an ST guy.

But their search engine is full sh...: doesn't show up anymore!

It's called "STUSB_NVM_ReadWrite_Utility_v1.00.zip".

ST search engine can't find it!

Maybe you could give it a try: I'm no good at sending scripts and commands on a prompt editor... I'd rather use a dumb interface for stupid users.

If you have a email address, I can forward it to you.

Regards.

Hello,

Google engine is outstanding : it found the software.

Just let me know if it helps.

Bye.
