Flashing ATSAMV71N20 with ARM-USB-TINY-H + ARM-JTAG-SWD

[gyurco]

Hi!

I'm trying to flash the above combo with openocd, however I just get an error:

Code Select Expand

openocd -f interface/ftdi/olimex-arm-usb-tiny-h.cfg -f interface/ftdi/olimex-arm-jtag-swd.cfg -f target/atsamv.cfg --command "adapter speed 10000; init; reset init; sleep 1; flash protect 0 0 last off; flash erase_sector 0 0 last; flash write_bank 0 firmware.bin 0; resume; shutdown"

Debugging with GDB however works. Any idea what can be wrong?

Solved: 10000 kHz for the adapter clock speed was too much, it works with the default (1800).
