Okay, I can see there is major of interest in the subject of
OpenOCD-BOX, this is good, thanks :-)
As there seems to be plenty of hardware solutions, I think we should
invent one common buffer design to be applied on any GPIO and allow
JTAG, SWD, SPI, I2C, 1Wire, etc using common signal definitions. We
should design such buffer as separate module to be applied on
different hardware solutions, so we have common signals across
different solutions, and probably extremely cheap adapter board. Each
openocd-box solution will have its own GPIO drivers but signals will
be common among them and this will help maintenance and compatibility
even in case of different hardware..
Buffer should allow to input/output/tristate lines connected to a
target device and shift voltage levels safely between interface
hardware and target system - {1.8, .., 5V} would be fine..? Something
as presented in KT-LINK, maybe this design can be reused with author
permission..? Anyone has experience in such designs and want to take
the challenge? :-)
I have received Carambolla today, but I will have time to play with it
with start of July, until then its hell on earth for me :-(
Best regards! :-)
