Parallella as development board

[zodane]

Hello,
It has been almost a year now since i bought my Parallella 7020.
If i buy a porcupine and a jtag cable, can i use my board for standalone application (without Os).
how can i program the epiphany (in standalone mode), maybe one arm should drive the epiphany while the second will run application, is the epiphany worth that!!

The Zynq boots from SD card (by loading kernel and bitstream), you don't need a Porcupine to change that. The Epiphany chip is connected to the PL part (FPGA) of the Zynq. If you implement the eLink protocol and a kernel loader in the FPGA, then you won't need the ARM cores at all to run stuff on the Epiphany. Lots of work, little gain.

I am not sure what you actually want.

Thank you for feedback Sebraa.
I want a full communication between the 2 ARM cores , epiphany and PL.
I want to be able to debug software and hardware.
And finally i don't need an operating system (bare metal application).

You didn't answer the question.

Reading a video file from SD card and doing some processing on it is easy, given Linux.
Using the Epiphany for the processing can be doable, incredibly hard or plainly impossible, given Linux and eSDK.
Changing the FPGA bitstream to do the processing can be done, given Linux. Other's have done it.

Ditching Linux on the PS needs a really good justification.

Thank you Sebraa i will buy a porcupine daughter card + a hs2 jtag from digilent and see what can i do.
