First off, there's no big need to update TeleMini firmware at this point; the only fix relevant is to make the beeper sound when power-on self-test fails. > Can I cut up a USB cable & connect the > USB data+, data- and ground wires to the TeleMini v3 pins 1, 2 & 3? Yup. I have a cable wired up for this to do the device bring-up. On the connector: 1 USB D- 2 USB D+ 3 Ground <- square pad 4 Reset 5 SWD I/O 6 SWD CLK It's wired like this so that I could use our "standard" debug connector (four pins: clk, i/o, reset, gnd). But, having built a seven-pin connector that does both debug and USB, it doesn't actually matter anymore. > Sorry to be a pain - If this thing was cheap I’d just try it.

You can check the release notes in upcoming releases to see if there's a critical fix for TeleMini; I always review all of the changes before finishing up a release to make sure I don't miss one. -- -keith
