Hi all,
Do any of you know any alternate ways to program arm chips other than a Segger J Link? Segger is a bit proprietary about it's stuff which makes configurability a bit tricky... but then, they do good work so I'd like to use them but am having a difficulty.
I've been looking into using this( https://www.segger.com/products/debug-probes/j-link/models/j-link-edu-mini/) for the next revision as it has SWD and a virtual com port, however it does NOT supply 5V which is key function as power is need to either charge the battery or run the thing...
If you used a different platform - say OpenOCD, are there other more open programmer options available?
Ideally would like SWD programming, Virtual COM port AND 5V supply, for cheap!?

I've used an LPC Link-v2 before, but not sure if it will work on the particular chip you're interested in programming

First, a lazyweb question:
What's a good starting point to look up documentation of the SWD, for people more familiar with hardware than complex firmware/software?
Then:
What, exactly, is a Virtual COM port? Several possible definitions come to mind.
Next:
How feasible is it to design/adapt a dedicated programming PCB from as open as possible sources?
If feasible, finally:
On the physical/electrical interconnect level, what connection do we want between programmer PCB and the ADuCM350 board?
Does galavnic separation for a biomedical [modulo FDA approval] product make sense?
If so, how much effort would galvanic separation be worth?

Hi Jean,
sorry to have missed your meeting at 34C3 :-/
However, I very much enjoyed your talk and the group conversation we had
afterwards!
I very much like the Black Magic Probe (BMP) - itself a (mature) open
source project:
https://1bitsquared.com/collections/embedded-hardware/products/black-magic-probe
/ https://github.com/blacksphere/blackmagic/wiki /
https://www.kickstarter.com/projects/esden/1bitsy-and-black-magic-probe-demystifying-arm-prog
(By the way: Pjotr also attended 34C3 ;-))
The nice thing about BMP is that it actually runs an embedded GDB server
- which means you can simply connect to it from gdb without having to go
through the hassle of setting up OpenOCD ore anything like that. It also
allows for Semihosting / Host IO and provides limited support for TRACESWO.
The hardware is similar to a standard ST-Link adapter, clones of which
you can get for around $2. In fact, the software runs happily on these
clones (although with these you have to use an additional USB/UART
adapter to connect to the target, because the clones miss a few GPIOs):
https://madnessinthedarkness.transsys.com/blog:2017:0122_black_magic_probe_bmp_on_st-link_v2_clones
Unfortunately, it can only supply 3.3V to the target, so it does not
quite fit your bill, although you could probably overcome this using an
additional USB/UART adapter with 5V output.

Thanks. Both LPC-LINK2 and Black Magic Probe look like more open alternatives to SEGGER which is very big on black boxes(but the standard).
Segger also has a new cheaper educational mini debugger tool for only $22. I think I'll just go with SWD pins and a separate 5V through USB, then people can choose either.

Thanks Micah, it was exciting to see the post listing OpenEIT next to OpenWater and I hadn't heard of Furaxa - they look very interesting!
