- ARM923EJS:
- reset run/halt/step is not robust; needs testing to map out problems.
- ARM11 improvements (MB?)
- - fix single stepping (reported by ØH). Michael Bruck explained
- that what's required is to emulate the current instruction(just like the
- arm7 code) to know what address to set the breakpoint at for single
- stepping an instruction.
+ - fix single stepping (reported by ØH). Need to automatically
+ use hardware stepping if available.
+ - hunt down and add timeouts to all infinite loops, e.g. arm11_run_instr_no_data would
+ lock up in infinite loop if e.g. an "mdh" command tries to read memory from invalid memory location.
+ Try mdh 0x40000000 on i.MX31 PDK
+ - mdb can return garbage data if read byte operation fails for
+ a memory region(16 & 32 byte access modes may be supported). Is this
+ a bug in the .MX31 PDK init script? Try on i.MX31 PDK:
+ mdw 0xb80005f0 0x8, mdh 0xb80005f0 0x10, mdb 0xb80005f0 0x20. mdb returns
+ garabage.
- implement missing functionality (grep FNC_INFO_NOTIMPLEMENTED ...)
- thumb support is missing: ISTR ARMv6 requires Thumb.
ARM1156 has Thumb2; ARM1136 doesn't.
