Logs
| 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. |
| Read about register manipulation in the ARM guide. Continue working on process creation. |
