Week 1: May 30-June 2 |
Began attempts to boot the full version of Embedded Xinu kernel with Raspberry Pi 3 |
Researched a Linaro Cross-Compiler to use for its Cortex A-53 ARM processor with ARMv8 architecture |
Drew diagrams of the boot sequence and compilation for better understanding of the Pi 3's mechanisms |
Traced through the dynamics of written Assembly code in the full research version of Xinu |
Week 2: June 5-9 |
Tested the LED program in updated Assembly code. Began testing the Serial Port Transceiver driver for the Pi 3 |
Read about Raspberry Pi bare metal programming via online sources |
Read about how the Raspberry Pi 3 controls the frequency of its UART pins |
Read ARM processor documentation about configuring UART clock frequency |
Used the oscilloscope in attempt to obtain the clock frequency of the UART pin |
Week 3: June 12-16 |
Read an online textbook about the ARM processor of the Pi 3. |
Successfully controlled the PL011 UART with a 48MHz frequency. Began porting full version of Xinu. |
Read ARM64 documentation on registers to use with process interrupt handling. |
Began working on the context switch for the 64-bit architecture. |
Finishing work on the files necessary for context switching and rescheduling. |
Week 3: June 19-23 |
Continue working on the boot functions of our implementation. Finished the Research Conduct course. |
