HPS Booting - Preloader boot from RAM

Hello, I am working on a project in which the FPGA is configured using Passive Serial and the HPS is booted completely from the FPGA (both the Preloader and Bare-Metal application will be stored in...

Hello and thank you for the reply,

I have read through all of the discussions but I am unsure if they help me. It seems as though the discussions mainly focus on launching a bare-metal application from an external SD card whereas I am interested in launching from FPGA memory. I will eventually be working with custom hardware without an SD card slot and both the hardware and software design should be able to be configured through the Passive Serial connection. For reference, I am essentially trying to replicate this tutorial (https://rocketboards.org/foswiki/Documentation/BootFromFPGA151) but instead configure the Preloader to run the HPS software from another On-Chip Memory (RAM or ROM) component.

From the posts, I gather that I only need to use the mkimage utility on the compiled bare-metal application if I plan on using u-boot, is that correct?

I apologize if I have misunderstood the information given in the posts. I do not have a software background and some of the concepts are unfamiliar to me.

Thanks,
