# List of board modifications to enable SRST, as reported in
|
|
|
|
|
# ST Application Note (FIXME: add reference).
|
|
|
|
|
# - Modifications on the top layer:
|
|
|
|
|
# 1. replace reset chip U4 with a STM6315SDW13F;
|
|
|
|
|
# - Modifications on the bottom layer:
|
|
|
|
|
# 2. add 0 ohm resistor R10. 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 and solder it between R10 and R54:
|
|
|
|
|
# - one pad soldered with the pad of R54 connected to 3.3V (this
|
|
|
|
|
# is the pad of R54 far from JTAG connector J4)
|
|
|
|
|
# - the other pad soldered with the nearest pad of R10.
