Hi All,

Chip: STM32F100C4

Custom board

Need some help.

I download the program via from IAR embedded workbench flash loader using ST-Link/V2. Every thing is ok. But i have to manually reset the pin no.7 to get it working

Setting the Reset PIN in the options box seems to have no effect.

It should automatically reset after download right.

Can some one help.

Thanks and Regards,

Jai.

    For starters, get the most current drivers, they have been posted again on the forum within the last few days.

    Programming works when using ST Visual programming IDE.

    No problems.

    With Keil  + ST-Link  /V2 it does not even program/ download in  to flash.

    works ok in debugging mode.

    With the IAR + ST-Link/ \/2 debugging is ok. flash downloading is also ok. but does not do a proper reset.

    Consider other JTAG pods, U-Link, J-Link, as the integration is a lot more polished.

    Consider the wiring of the ST-LINK, and reset/power-on-reset connections. The resets should be open-drain, another common failing is people connecting the resets to other circuits/drivers using push-pull. Also check the communication mode SWD vs JTAG.

    Is the experience different with a standard dev board, vs your custom board?
