  1. # Configuration for the ST SPEAr300 Evaluation board
  2. # EVALSPEAr300 Rev. 1.0, modified to enable SRST on JTAG connector
  3. # http://www.st.com/spear
  4. #
  5. # List of board modifications to enable SRST, as reported in
  6. # ST Application Note (FIXME: add reference).
  7. # - Modifications on the top layer:
  8. # 1. replace reset chip U4 with a STM6315SDW13F;
  9. # - Modifications on the bottom layer:
  10. # 2. add 0 ohm resistor R10. It is located close to JTAG connector.
  11. # 3. add a 10K ohm pull-up resistor on the reset wire named as
  12. # POWERGOOD in the schematic.
  13. #
  14. # The easier way to do modification 3, is to use a resistor in package
  15. # 0603 and solder it between R10 and R54:
  16. # - one pad soldered with the pad of R54 connected to 3.3V (this
  17. # is the pad of R54 far from JTAG connector J4)
  18. # - the other pad soldered with the nearest pad of R10.
