The parasitic capacitance of the three probe input pins and R1 formed a
...
quite formidable low-pass filter that almost completely eliminated the
1 MHz signal.
- cntr/cntr.sch, cntr/cntr.brd: changed R1 from 100k to 1k to increase
input bandwidth

Got "cntr" to show signs of life. It was the watchdog, as usual.
...
- TODO: "cntr" now makes it to DFU and beyond
- atrf/fw/common/config.h (PLATFORM_SETUP): rename to PLATFORM_ENTER
- cntr/fw/common/config.h (PLATFORM_SETUP): rename to PLATFORM_ENTER and
make the new PLATFORM_SETUP turn off the watchdog

the usual USB stack
- cntr/fw/cntr/cntr.c: initialize and poll USB
- cntr/fw/cntr/cntr.c, cntr/fw/cntr/ep0.c: added counter application
- cntr/fw/common/config.h (PLATFORM_SETUP): enable the crossbar

cntr/cntr.brd: remove the ground fill. The board got a bit messy with it.
...
Bumped the version to V1.
