ARM and FPGA interaction

[javiruni10]

New here, so hello everyone.

I am attempting a fpga implementation making use of the inputs of the RedPitaya.

I got a RedPitaya 125-14, tried to understand the SoC (Xilinx Zynq 7010) and how it works but i can't get to understand whether i can directly program the FPGA without involving the ARM processor.

My goal is to acquire the data, pass it through the ADC, operate with it at the FPGA and store the processed data onto the SD Card.

Also, do i neccesarily need to make use of the JTAG connection to bare program the FPGA.

Thanks in advance.

Hello javiruni10,

I am moving this topic to the FPGA-related topics.

Here are a few relevant links to this (might not be relevant to your specific application):
- General Red Pitaya FPGA tutorial: https://redpitaya-knowledge-base.readt ... g-the-fpga
- Red Pitaya FPGA developer's guide: https://redpitaya.readthedocs.io/en/lat ... pga-image

Yes, you can program the Red Pitaya's FPGA directly without involving the processor.

One of the users also made a guide on bare metal programming:

Thanks a lot!
