[OpenOCD-devel] Flyswatter + AR71xx (Mikrotik Routerboard 450g)

[Ondrej M. <ond...@ni...>]

This is the last device I'll be testing the Flyswatter with.

openocd  -d --file interface/ftdi/flyswatter.cfg --file target/ar71xx.cfg

I had to add "adapter_khz 1000" at the end of ftdi/flyswatter.cfg,
otherwise I'd get a complaint that adapter speed is not defined (not
sure if the speed is correct).

This time the error is really early with "Error: JTAG scan chain
interrogation failed: all ones" (see attachment with debug log)

I rechecked pins and even made sure with JTAGenum the pins in openwrt
documentation match - JTAGenum finds the JTAG interface at the same
location (http://wiki.openwrt.org/toh/mikrotik/rb450g#jtag).

After some preliminary googling it was suggested that ar71xx.cfg might
be out of date for EJTAG, but I'm not sure.

Maybe someone has better insight?

Thanks,
  Ondrej
