# Configuration for the ST SPEAr320 Evaluation board
# EVAL_SPEAr320CPU Rev. 2.0, modified to enable SRST on JTAG connector
# http://www.st.com/spear
#
# List of board modifications to enable SRST, as reported in
# ST Application Note (FIXME: add reference).
# - Modifications on the bottom layer:
# 1. replace reset chip U7 with a STM6315SDW13F;
# 2. add 0 ohm resistor R45. It is located close to JTAG connector.
# 3. add a 10K ohm pull-up resistor on the reset wire named as
# POWERGOOD in the schematic.
#
# The easier way to do modification 3, is to use a resistor in package
# 0603 or 0402 and solder it between R15 and R45:
# - one pad soldered with the pad of R15 connected to 3.3V (this
# is the pad of R15 closer to R45)
# - the other pad soldered with the nearest pad of R45.
