 # Baremetal IDE Lab
-Baremetal IDE is an SDK developed and maintained by the SLICE lab at Berkeley which allows you to quickly develop C/C++ for chips developed in Chipyard. As implied by the name, Baremetal IDE focuses on providing a bunch of libraries, scripts and device drivers to build “baremetal” programs which run without an operating system like Linux or Zephyr. Programming for bare metal means that you don’t have a bunch of operating system services that you may be used to like multithreading, device drivers, dynamic linking, etc, but in return, you have full control of your code and can extract the maximum amount of performance out of your chips. Baremetla IDE provides a thin layer of drivers and libraries that handles things like malloc or print. This lets you focus on building your workloads to test your chips instead of spending your time messing with linker scripts, stdlib versions, and device drivers.

 Since the actual HeatherLake setups are a bit fragile and require lots of external support equipment, we’ll be running all of these labs on an emulated chip on a Datastorm FPGA. This lab will bring you through the whole process of getting started with a new chip, building a Board Support Package, writing some basic drivers, and benchmarking a simple accelerator.

 Unfortunately, due to the way Unix handles serial devices, the exact device ID changes every time you unplug and replug your device. The best way of figuring out which serial port is which is unplug the device you are trying to find the id of, run the command `ls /dev/ttyUSB*` to lists out all remaining USB serial ports, plug the device in again, and run the command one last time to find the new serial port. For the lab, UART-TSI is on the usb port hooked directly up to the FPGA, not the one plugged into the FT-LINK.
