i'm pretty sure my company will decide in favour of the stlink
<PaulFertser>
Why not jlink?
<braunr>
or that
<braunr>
but not something home made, which risks of unavailability :
<braunr>
:/

<PaulFertser>
stlink v3 especially is kind of offending, ST decided to somehow cripple it to make debugging non-st targets impossible.
<braunr>
ugh
<karlp>
I've used an stlinkv2 for years with ITM, and been very happy with it. it's not as fast as a v3, or an orbtrace or a jlink pro, but it's _far_ more than "just debug" already,
<karlp>
so ymmv, depends how much trace you _reallly_ need.
<braunr>
i might need a lot
<braunr>
not sure yet
<PaulFertser>
Probably that's an opportunity to get a decent LA.
<braunr>
maybe
<braunr>
or maybe just a high speed serial adapter
<karlp>
well, you "should" have an stlink lying around already, just on any nucleo/disco board, that's been enough for me for ages :)
<braunr>
i actually don't :)
<braunr>
well that's not true, i have on an stm32mp1 discovery board
<braunr>
but that's it
<karlp>
yeah, CN12 probably has swd, but unlike the "regular" disco/nucleo boards, it doesn't have headers fo rtargetting an external device.
<karlp>
well, it's ~10 currency units addon to your next distributor order, might be easier to get started than some other tools?
<braunr>
i already have something that works
<braunr>
now i'm looking for something that another developer can easily and reliably use, without wondering what pin goes where :p
<karlp>
the "hardest" bit is really, "what debug connector did you put on your target board" vs "what debug connectors does my dongle hw have" IMO :)
<karlp>
the rest is all ~interchangeable
<braunr>
yes
<braunr>
but smart people made it sure that it you have the standard jtag pins, you also can have swd+swo
<karlp>
what's the target hw again?
<braunr>
stm32f7
<braunr>
custom board
<braunr>
with a 20pin standard jtag connector
<karlp>
stlinkv3, orbtrace, jlink-pro all have versions with the 2x5x1.27mm pitch
<braunr>
yes that won't be a problem fortunately
<karlp>
you put the old jumbo 20 pin header on? whee
