Hi Haojian, can you please check what "aarch64" command can do ?
Although the aarch64 code is derived from V7, I think aarch64 has the ability to read/write coprocessors by one if its own subcommands.
From gdb:
- "mon aarch64" - from telnet to port 4444, "aarch64" help command from telnet to port 4444 should describe all of the available commands including aarch64.
best regards, -Phil

Hi Philip & Peter,
I found there's the limitation on dumping coprocessor value on armv8. My platform is hikey.
I found there're "hi6220.cpu" and "arm" commands in openocd. But I failed to dump any coprocessor value by these commands. After checking the sourcecode, I found that they're just used to dump ARMv4 -- ARMv7. And there's no really support in ARMv8 to dump coprocessor. Do you plan to enable this feature on ARMv8?
