I mentioned before once the backup battery was happy I started seeing multiple goes quickly on Vsys, I noticed that when it does this, the effect on 3.3V rail is cumulative. (See the attached pic). The number of goes it has before stopping and waiting for 30ms for the next batch is highly erratic and variable and it seems that is also a clue. Again I tested bringing external 3V3 to IO_3V3 and it causes the device to start OK without battery. I tried it via 150R and it worked sometimes, but after that it needed shorting again to make it work, not sure what changed. It lifted the starting level of the 3V3 rail depending on the series resistor, so maybe the variability is down to the same thing that decides the number of tries on Vsys in quick succession. | Yeah, just heating my iron to do the same on mic (noise) side to proof some of | the alternative reworks I suggested. | So at the end of the day we will need a good beer both of us ;-) Sadly not a booze day here but have one for me. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkhqO8AACgkQOjLpvpq7dMq8dQCfTqfKP9L93gwTaqsZzHt4qL+/ 3DwAniMX57tCzvxFJdRqzEbrRYxhOcRN =mVtS -----END PGP SIGNATURE-----
