Dear all,
TI ARM guru Zhaohong has provided the HDK schematics (tms570ls3137) within this thread.
On my desk I have a board with the revision number - PCB 4197281 REV D. According the circuit lines in the above mentioned schematics (page 25 - reset) I would assume that following points / pins have an equal voltage level (there is a short connection - just "pure wire" - betweem them):
(joint of R268 and C141) AND
(joint of pins 2, 5, 7 of the circuit U32) AND
(R190 - to ETH_RESET_n) AND
(pin 5 of the connector J10 - WARM_RSTn)
But my measurement (with a normal multimetr) results with different conclusion... Only following points are directly connected:
(R190 - to ETH_RESET_n) AND
(pin 5 of the connector J10 - WARM_RSTn)
May you confirm that the mentioned schematics is valid for my board revision? Is there some part missing within the schematics, is not?
Many thanks in advance,
best regards, Jiri
