05:16 <skmagiik> Hey all, I can't seem to find any updated documentation regarding read_memory that I see referenced and used in various scripts.

05:16 <skmagiik> Open On-Chip Debugger

05:16 <skmagiik> > version

05:16 <skmagiik> version

05:16 <skmagiik> Open On-Chip Debugger 0.12.0+dev-00825-g250ab1008 (2025-01-06-23:09)

05:16 <skmagiik> > mem2array test 32 0x0 16

05:16 <skmagiik> mem2array test 32 0x0 16

05:16 <skmagiik> DEPRECATED! use 'read_memory' not 'mem2array'

05:16 <skmagiik> invalid command name "read_memory"

05:16 <skmagiik> Traceback (most recent call last):

05:16 <skmagiik> , in mem2array

05:16 <skmagiik> > read_memory

05:16 <skmagiik> read_memory

05:16 <skmagiik> invalid command name "read_memory"

06:21 <Hawk777> https://openocd.org/doc/html/General-Commands.html#index-read_005fmemory

06:22 <Hawk777> I’ve personally used it on 0.12.0.

06:22 <Hawk777> Dunno why you’re getting invalid command.

06:23 <Hawk777> Although, I think I only tried it via the Tcl RPC port and not the Telnet port. But I don’t think that should matter.

06:25 <skmagiik> I figured it out.

06:25 <skmagiik> (I don't have much openocd experience on unknown targets/without pre-provided configurations)

06:25 <skmagiik> I had to define a target manually and once I did so it was able to use read_memory

06:32 <Hawk777> Ahhh, gotcha. Yeah if you don’t define any targets you’ll get JTAG TAPs or whatever, but you won’t be able to do much useful with them because OpenOCD won’t know what they are (what type of CPU or whatever) and therefore how to access memory (or if they even *have* memory).

06:52 <skmagiik> Yeah, I though since it identified it `JTAG tap: cortex_a.cpu tap/device found: 0x4ba00477 (mfg: 0x23b (ARM Ltd), part: 0xba00, ver: 0x4)` that it would use that target

07:20 <Hawk777> I think that’s just decoding the bits of the IDCODE.

07:20 <Hawk777> So a table of manufacturer IDs or something.

10:24 <PaulFertser> skmagiik: and for the reference, the documentation is maintained along with the source code so if you have openocd binary you should have corresponding Info manual along with it.
