dsendcomm/firmware/Sendcomm-OCD.cfg

#
# SendComm EDU (SAMR34 Cortex-M0 ISA) developer kit OpenOCD configuration
#
# Note: Build openocd(1) from its source repository to benefit from the most
#       recent SAMR34 definitions, because the chip in use is relatively new.
#
# Use with a firmware binary (bin) or archive (elf) in the following way:
#
# $ openocd-git/src/openocd -s openocd-git/tcl \
# -f dscomm-0.9.2/document/sendcomm-ocd.cfg \
# -c 'program SendcommLWOTAA-rel.elf verify reset exit'
#
# ...and after that, Sendcomm firmware is running.
# To use it, first log into the Sendcomm host and:
#
# $ screen /dev/serial0 115200 8N1
#

# modify to the debugger
#adapter driver cmsis-dap
adapter driver jlink
#jlink serial 123456789

# choose swd (not jtag)
transport select swd

# allow for host reset
