14:07 <jancoow> How to configure openocd to utilise the reset pin when start conneting to a ATSAML21 target

14:08 <jancoow> it seems only to be working in hot plug mode

14:09 <Haohmaru> :/

14:09 <jancoow> however, due my program code I cannot use hot plug mode and want to use cold plug mode

14:09 <Haohmaru> is there that special procedure involved in this?

14:09 <Haohmaru> right "cold-plug"

14:10 <jancoow> so I now "bricked" my board to not be able to connect to it because i configured the debug pins in the software code

14:10 <jancoow> so need to wipe it in atmel studio in order to connect to it again..

14:10 <jancoow> Cold-Plugging is the detection of a debugger when the system is in reset. Cold-Plugging is detected

14:10 <jancoow> when the CPU reset extension is requested, as described above.

14:11 <Haohmaru> i was trying to do that on an SAME54 which i "secured" and it doesn't work, i found some old patch and posts about "cold-plug" implemented in the other "target" for the smaller SAM chips (cortex-M0+ and such) and i tried to use that

14:11 <jancoow> oh really?

14:11 <jancoow> so officially they only implemented hot plug mode?

14:11 <Haohmaru> i had to fool openocd that this is not a SAME54 and had to use an older version of openocd where this patch works

14:11 <Haohmaru> iirc

14:12 <jancoow> that's annoying for development as well..

14:12 <jancoow> strange nobody ever enabled cold plug mode

14:12 <Haohmaru> and iirc i tried to modify current openocd with this "cold-plug" thing but i failed to

14:12 <jancoow> it's the most easy one

14:13 <Haohmaru> i forgot the details, but basically newer openocd reads a few things on connect to the target, and when the chip is "protected" some of the registers read back as "errors" or something, but this is the expected behavior when "protected" and should be ignored, but openocd doesn't ignore it and stops at this point

14:13 <Haohmaru> or something like that, i don't remember anymore

14:23 <PaulFertser> jancoow: what exactly do you want for reset pin to do? "reset_config connect_assert_srst" probably?

14:25 <Haohmaru> actually, it might actually work on the MCUs which are on that config, my issue was that i needed it for SAME54 which is treated as a different thing in openocd

14:25 <Haohmaru> so listen to mr PaulFertser
