Or else simply put shift register logic to get your parallel data..

If your operating frequency is less

Maybe I should start by asking: can the pins that I've marked on the picture be accessed directly? The individual pins don't seem to be marked, are they only meant for programming the chip? If not, how do I know what they're called when writing Verilog code?
If it still actual, you can use one PMOD for direct access to programmable logic. This is the down 12 pins that you've marked.  The Pmod connector is a2x6 right-angle, 100-mil female connector that mateswith standard 2x6 pin headers available from a variety of catalog distributors. The12-pin Pmod connector providestwo VCC signals (pins 6 and 12), two Ground signals (pins 5 and 11), and eight logic signals. VCC and Ground pins can deliver up to 1A of current.Jumper JP12 selects the Pmod Vcc voltage(3.3V or 2.5V)in addition to selecting the VHDC voltage. Pmod data signals are not matched pairs, and they are routed using best-available tracks without impedance control or delay matching. Pmod Pinout

Hi guys, I've just created a Petalinux project. I can boot the system, but there's a bunch of Linux commands that I cannot use.

root@dpu_without_bsp:/bin# ls
-sh: /media/card/bin/ls: /usr/bin/coreutils: bad interpreter: No such file or directory
root@dpu_without_bsp:/bin#

Why is happening this ?

If I go to /bin and I execute ./ls, the command works.

Thanks in advance

1. Check your path with
echo $path

2. Run command which-a ls in both dirs and check that it's the same ls

3. This fix looks relevant

Depends on which chips you are going to work

Xilinx doesn't utilize gpu
32gb of ram memory is enough up to virtex us+ 9UP
cpu also look powerful enough

What is needed in the case of big ultrascales boards?

64-128 GB RAM, think it's unaffordable for a laptop

you will be able to work with virtex us+ but it will be slow as hell
