Interesting, wonder what I'm doing wrong then. I'm using an actual STLink/V2 programmer device, which seems to work fine for actually debugging the SM1000, just not programming it. > I'm not familiar with the nJRST pin on the uC, can you pls describe > exactly what connection you would like to see (i.e. pin numbers, where > the net would be routed to)? My apologies, it's called nJTRST; pin 90. It otherwise is known as PB4. > We have provision for a reset button SW5 (nRST pin 14 on the uC) on the > SM1000 which I found handy during development when I was flashing via > STLINK. Ahh, wondered what that button did. Didn't seem to do anything though. > I have found DFU mode comes up immediately every time, by holding PTT > down as the SM1000 is switched on.

Interesting, not sure what's going on then. The set-up here: - SM1000 has case open - STLink/V2 plugged into CN1 - my laptop (late 2008 Apple MacBook) plugged into "RIG SPKR" - an old pair of headphones (70's era paper cone ones) plugged into EXT SPKR - Power from 100Ah 12V AGM battery Some theories I'm thinking of: - Switch bounce? Maybe I'm not doing it right and there's just a little contact bounce as I'm holding it. - RFI? Here at The Gap, I'm practically in the shadow of Mt. Coot-tha, where there exists many high-power VHF and UHF transmitters for the local television and radio stations. Anyway, currently I've been attempting to get the speech prompts working. I note that the SM1000 here fails to pass through analogue or decode FreeDV 1600 since around revision 2482 (according to `git bisect`) and I'm just trying to figure out why. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
