Bonobo JTAG/SWD Debug Cable¶
iPhone debugging requires proper tools.
The Bonobo cable connects to your target through Lightning and allows CPU debugging through JTAG/SWD using OpenOCD + AArch64 GDB. Among others, you can: access all CPUs and registers, single step, put hardware breakpoints, dump memory, etc… Perfect for security research.
The target serial console can be accessed on the control PC through Minicom (iBoot prompt), as well as Lightning USB (For DFU, USB exploitation, etc.)
To be able to use this cable, the target system (iPhone) must be demoted to allow JTAG/SWD thanks to @axi0mX.
