Re: Do we get Vulkan on Pi 4?

Khronos has nothing to do with implementation of Vulkan, they just define the standard and compliance.
It's not their intent or purpose to create the drivers for the devices.
Pretty sure I saw Khronos offer $$$ for a port of OpenVX to Raspberry Pi 3?

Re: Noobs or Direct?

Only noobs use Noobs :D
You could try PINN.
Or just use the normal Raspbian, it is quicker to get running.

Re: Any Tutorial to Create a Cross Compiler for ARM? Rpi3

You can make a cross compiler on the Pi's. It took 13 hours last time I tried. If you want to compile for aarch64 you can grab Sakaki's Gentoo64 which is ready to go. Native compiling is better and can be faster. Sakaki even has a Raspbian spawn spin that can do 32 and 64bit ARM compiling. https://g...

There's a long and hard, but beautiful road ahead of you :-) You can take the bypass unless you like those windy, bumpy roads. No matter which way you go expect a long journey of learning. Currently baremetal can be done in asm, C, C++, Free Pascal, Rust and ????? Turning those into an OS is a bit ...

Re: Raspberry Pi 4

Dunno why in 2019 GPU drivers/programming is still such a pain in the ass. Libraries are huge. APIs are overcomplicated. Drawing a simple 2D line is ridiculously hard if you want proper hardware acceleration... or rely on libraries like OpenVG but it seems quite slow from my experiments. I dream of...

I am thinking multiple version of Computes.
CM4 and CM4+ which has the PCI-e broken out.

Those USB/Lan parts can be on the motherboard, two types of motherboards?
Third party MB's, 6 UART versions?

Wonder if BCM can make enough 2711's?
