It's highly recommended to use a Linux-based desktop development environment when configuring/building petalinux, as that is what we found had the least amount of issues. Petalinux tools also only runs on Linux machines, and it's clear that Xilinx prefers a Linux development environment for their software tools.

The baremetal app for this project is [here](https://git.ece.iastate.edu/sd/sdmay23-47/-/tree/master/petalinux/sw/platform/CyDAQ_sampling). It is launched from Petalinux using the [remoteproc](https://www.kernel.org/doc/html/latest/staging/remoteproc.html) framework. When this occurs, both CPUs are then running separately, and need to use shared memory to communicate with each other. We use a library called [openAMP](https://www.openampproject.org/) and [rpmsg](https://www.kernel.org/doc/html/latest/staging/rpmsg.html) to do this. There is also an additional memory region carved out specifically for storing sample data, which the baremetal writes to whenever the ADC triggers an interrupt. Once sampling is stopped, Petalinux reads from that same shared memory region and sends the sample data back to the host PC.
