My research project focuses on porting Embedded Xinu into our new, multi-core Raspberry Pi 3s. While my project has just begun, my log thus far is below.
Day 1:
Orientation
Day 2:
Booted Raspbian onto Raspberry Pi 3
Realized Pi is 64 bit and not 32 bit... Found new cross-compiler since old one won't work
Attempted to boot Xinu onto Pi 3 (not yet there)
Day 3:
Got a bare metal program (taken from Tristan Gingold) to boot on the Rasberry Pi and turn on a light
Day 4:
Tried booting a light version of Xinu taken from an old Operating System's homework (didn't work)
Started to convert the code that turned the light on in the C file to assembly (ARM64) to see if the booting process just wasn't getting to the C file
Day 5:
Converted C to assembly using the compiler (which we should have just done before)
Found that booting process wasn't getting to C file but was getting to assembly
Fixed code so light would turn on even when code was in C file
Still not receiving any input from the serial connection
Day 6:
Got serial connection working using mini-UART
Receiving wrong characters using pl011
Day 7:
Tried to find what the correct baud rate should be set to for pl011 (to no avail)
