We just got to use what we got I think.... there's a list of variants in docs folder, I don't think we find one that differs solely by this parameter. For example, we carefully match regulator function to variant-defined regulator on/off and voltage state in NOPOWER, other variants change those around basically because other NXP customers had designs that wanted the differences. They're probably not all equally available from stock either. And... the tight binding of the VB_SYS problem on A5 to inrush current parameter also set by variant... I don't think we dare change it if we want a chance of a "predictable ride" on power for GTA03. Very much "Devil we know". - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkjhGuUACgkQOjLpvpq7dMqHkQCbBlmlD/OrOqaTc6+w8TI3S82h EnoAn2EyU8kFNHYPI7WsYdyp/QGce/Tb =GGYU -----END PGP SIGNATURE-----
