18:53:13@korken89:matrix.orgkorken89Review done, some small updates needed :)

In reply to @arrowcircle:matrix.org
i also not so great in embedded world, so dont know what is ITM and how to properly use openocd, gdb and all that stuff
It takes some getting used to, but one gets into it quite quickly
18:53:59@korken89:matrix.orgkorken89Especially with the rust-embedded channel, a lot of good help there

I have gotten this when the FW on the stlink was old
19:01:36@arrowcircle:matrix.orgarrowcirclelatest firmware
19:02:11@korken89:matrix.orgkorken89Bad cables maybe?
19:04:04@arrowcircle:matrix.orgarrowcircledont think so. they are short
19:05:06@korken89:matrix.orgkorken89Weird
19:15:08@arrowcircle:matrix.orgarrowcirclemaybe my macosx filesystem is caseinsensitive?
19:18:57@korken89:matrix.orgkorken89That is fine, I can fix that after a merge :)
20:02:37@korken89:matrix.orgkorken89 japaric: If you are around, can you have a look at my CI PR in the examples repo?

That can happen for many reasons. Last time I saw it, my friend had failed to install a bootloader, and it did that unless the reset button was held while openocd was running
08:59:52@arrowcircle:matrix.orgarrowcirclebut how to fix it?
09:00:03@arrowcircle:matrix.orgarrowcircleis it somehow connected with rtfm?
09:00:20@thezoq2:matrix.orgthezoq2In that case, hold reset button, plug it in, launch openocd and program using GDB
09:00:40@thezoq2:matrix.orgthezoq2I think I have fixed similar issues by moving the boot pins occationally
09:01:55@arrowcircle:matrix.orgarrowcircleany way to fix it software way?
09:01:57@arrowcircle:matrix.orgarrowcircle * any way to fix it software way?
09:02:17@thezoq2:matrix.orgthezoq2Nothing that comes to mind
09:03:18@jschievink:matrix.orgjschievinkupdate openocd (install from git), and check your wiring
09:13:38@harrysarson:matrix.orgharrysarson arrowcircle: macos is often case insensitive (https://apple.stackexchange.com/a/71360)
09:14:43@arrowcircle:matrix.orgarrowcircle jschievink: it's from xpack for windows and from brew for mac os x
09:15:37@jschievink:matrix.orgjschievinkIs it up to date though?
09:15:44@arrowcircle:matrix.orgarrowcirclesure
09:15:53@arrowcircle:matrix.orgarrowcircleinstalled 2 days ago :)
09:47:16@jschievink:matrix.orgjschievinkyes, but what version? openocd doesn't do releases anymore since 0.10, and that version is often broken
