How to get bare metal app running independently on SoCkit?

I think you need to execute your application in the boot loader after the SOC boot up completes either from QSPI or NAND, long story...try to digest this

There is actually a good example in the "Hello World" example at this link: http://www.alterawiki.com/wiki/socbootfromfpga

It really all depends what you mean by "bare metal". You can probably get your code running in the On-Chip Memory by replacing the preloader with your own code and placing your code in the 0xA2 partition, but you'll have to do any chip initialization yourself. I haven't seen any good examples yet on working with no preloader, even though there is no particular reason why you couldn't.

You could even build an RTOS in DS-5 and port it over, if you wanted to try that.

Here's a related note: http://www.freertos.org/rtos_ports.html

There's quite a few ways, actually.

This looks like it may be helpful, thanks. As far as the RTOS link, not sure how that would apply since that would be using an OS, not bare-metal.

One of my favorite things to look at when trying to figure out baremetal is looking at how RTOSs implement it themselves. It at least provides another source for examples, besides the bare-metal thread and the user handbooks. Practical examples are sometimes surprisingly difficult to track down.

But this example of fpga only power up the preloader from the FGPA memory, there rest of the files looks like still remain it in the SD card.
