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

[<Pet...@t-...>]

Hello Paul,

I´ve tried the configuration

interface ftdi
ftdi_vid_pid 0x0403 0x6010

ftdi_layout_init 0x0008 0x000b
ftdi_layout_signal nTRST -data 0x0020 -oe 0x0020
ftdi_layout_signal nSRST -data 0x0080 -oe 0x0080

reset_config trst_and_srst

and it seems to work:

Then I´ve tried Eclipse with OpenOCD plugged in, but there I got an error:

Could you please tell me, that OpenOCD and the connection to the board via USB is running fine? Because then I have to look further at Eclipse and expecially my C program.

Thanks & best regards,
Peter

ftdi_layout_init 0x0008 0x000b
ftdi_layout_signal nTRST -data 0x0020 -oe 0x0020
ftdi_layout_signal nSRST -data 0x0080 -oe 0x0080

And probably you might need to use "reset_config trst_and_srst". Or
might not, please try both with and without.

You might want to join IRC for a more interactive debugging session.
