Introducing OpenOCD: Status of OpenOCD on AArch64
summary
OpenOCD gets concrete AArch64 support: target XML generation and GDB fixes enable reading and writing AArch64 SIMD/FPU registers (d0,d1) and bare‑metal debug on Hikey; testing uses BeagleBone Black, Hikey, Raspberry Pi 3 and Nitrogen boards with Bus Blaster and Flyswatter probes. A hacked test harness runs the GDB test suite and shows about 95% of GDB tests pass on AArch64; semi‑hosting support is nearly submitted. Multi‑core JTAG is still unreliable; single‑core debugging works.
