Re: passive heatsink shell case

Hi

Here is the link to the report I made to the seller.
https://www.dropbox.com/s/xk4yxoqlid2ri ... e.pdf?dl=0

He didn't even reply, but fully refunded me, so I really think the case I got is faulty !

Where is the GPU on the Pi4 ?

Hi everyone.

Here is my question :
Where is the GPU on the Pi4 ?

I've seen many presentation of it showing the CPU, the RAM, different port, but impossible to find a photo showing the GPU chip.

Is it included in the CPU (I mean inside the CPU) ?

Which one should I choose ?

Re: I cannot SSH my pi anymore

Ok friends.

Maybe I didn't expand the filesystem ? Is that possible ?

But I can go for a reinstall. So I'll get the new Buster instead Stretch ! The problem is always reinstalling all other needed software and configure everything. That's a lot of work each new install !

thanks you for your help.
