Re: [OpenOCD-user] Error: unable to open ftdi device

Hello Paul,

I´ve tried the direct flashing you have proposed. Here are the results:

So now also for me it looks, that I have to tell the linker where the flash memory begins. I have found the right script file, but at the moment I don't know how to use it within Eclipse.
But I think that this has no longer to do with OpenOCD.

So, thank you very much for get running OpenOCD for me.
Best regards,
Peter

"jtag init" is just bogus, it's done automatically.
"init" means switch from configuration phase to runtime phase.
"halt" means halt the target
"reset halt" means reset and try to halt the target before it executes
first instruction.

Please see the user manual for clarifications.

If you want to just flash use this:

openocd -f yourconfig.cfg -c "program your.elf verify reset exit"

Missing -c most probably.
