Hi everybody,
I am trying to use the stm3210e-eval with IAR (7.70). I have downloaded the demonstration software and followed the readme instructions. - EWARM - Open the STM3210E-EVAL_Demo.eww workspace - Rebuild all files: Project->Rebuild all - Load project image: Project->Debug - Run program: Debug->Go(F5) When I launch the debug, I have a fatal error ''Cannot connect to J-Link via USB''. The board is connected as USB and the screen and the LEDs are On but I do not see the board in the Windows device manager so I am not sure it is well detected although I installed the USB driver STSW-LINK009 is installed. Does someone know how to fix the problem ? Thanks very much for your help :)2016-06-28 03:32 AM
Hi Sam_Tlse
•Be careful about jumper settings on the board•Try to choose ST-LINK in the debug file menu•I recommend you to have a look to the UM0488 User manual for more details about Hardware features and board configuration-Syrine-2016-06-28 06:34 AM
Hi Syrine,
Thanks very much for your answer. For the jumpers, I put JP13 as USB, is that correct ? For J-Link, can you be more precise ? I am not very familiar with IAR and I do not see which menu you're talking about. Thanks,2016-06-28 11:49 PM
I tried on another computer and when I plug the board to a USB port, nothing happens. It looks like the board is not detected and I guess that's why IAR does not see anything. The power supply jumper is connected as USB. Is it the right way to do or shall I do something else to be able to communicate with the board via a PC ?

Things move-on. I changed the USB jumper so that the pull-up resistor is connected to USB+. Now when I connect the board to my computer, it is detected by Windows but not recognized (unknown USB device). I still have the same problem with IAR. Do you know if need to install some driver ?
