20:06 <danergo> PaulFertser: thanks a lot for your explanation of "trst" few days ago (I was out of office)

20:06 <PaulFertser> danergo: did it help? :)

20:07 <danergo> I'm going to test it right now, it seems it could flash my CC2652R, but I have to test it, if the firmware is really working :)

20:08 <danergo> Anyway, you (I believe it was you) mentioned that some series resistor might be needed to keep the flashing solid and stable

20:12 <PaulFertser> danergo: yes, because depending on different variables you might need to terminate the lines one way or the other for signal integrity.

20:13 <danergo> What is the best approach to detect where shall I use resistors?

20:14 <danergo> I'll desing my own PCB with this CC2652, and I'd like to use OpenOCD for initial flashing, therefore I'll have to "prethink" on designing these lines carefully, to let them working.

20:15 <PaulFertser> danergo: the best approach is to use a suitable oscilloscope as close to the target SoC pins as possible to measure the "ringing"

20:16 <PaulFertser> danergo: on your own PCB you can just put resistor footprints on every signal line and then you'll populate 0R if more is not needed.

20:17 <danergo> PaulFertser: thanks, that's a great idea

20:17 <danergo> only serial resistors might be needed, and not something like cap to GND, right?

20:17 <PaulFertser> Sometimes even obvious suggestion can be considered a great idea :D

20:17 <danergo> yes, especially when it's getting late :D

20:18 <PaulFertser> danergo: I'm not an EE but my impression is that for SWD or JTAG no caps are needed.

20:19 <danergo> perfect, thank you!

20:23 <PaulFertser> Best of luck with your project :)
