Greetings,
I am testing out the TUMPA v2 using OpenOCD for interface 0 as SWD and RealTerm for interface 1 as TTL serial uart. The TUMPA works fine as a serial device, loopback and all, until SWD is plugged in. As soon as SWD is plugged in, garbage on the loopback.
my tumpa.cfg is the stock openocd 0.9.0 version with the addition of
ftdi_layout_signal SWD_EN -data 0
For reference, the whole config:
interface ftdi
ftdi_vid_pid 0x0403 0x8a98 0x0403 0x6010
ftdi_layout_init 0x0038 0x087b
ftdi_layout_signal nTRST -data 0x0020
ftdi_layout_signal nSRST -data 0x0010
ftdi_layout_signal SWD_EN -data 0
reset_config srst_push_pull
Should I have mapped SWD_EN to another location for v2 TUMPA?
Cheers,
Joe
