Hi Stuart, The link seems to refer to flashing via STLINK - the 3 pin debug connector.
I have used STLINK to flash SM1000s many times during development - using just the 3 pins on CN1. This include 405 and 407 devices. I used a Discovery Board as the emulator "pod". 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)? 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. I have found DFU mode comes up immediately every time, by holding PTT down as the SM1000 is switched on. I just tried again on a new SM1000 and 5/5 times on first press. Perhaps you have a hardware fault? Cables? Contact me off list if you think its the SM1000 hardware. - David On 30/01/16 14:41, Stuart Longland wrote: > Hi all, > > Here's something we should add to the PCB for the next SM1000 revision, > a pin for nJRST. > > https://sourceforge.net/p/openocd/mailman/message/32108017/ > > Presently, due to that erratum, the only way to flash a SM1000 is using > dfu-util, and I'm finding that it might take as many as 5 or 10 attempts > of power cycling and pressing PTT in to get it into DFU mode. > ------------------------------------------------------------------------------ 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.
