The issue here is that timeout on Glamo MCI is in units of MMC clocks, but part of the latency for data access to the NAND in the card is in absolute time. So for example, it takes 100ms to get the data off the memory in the card. The absolute time that passes in the Glamo timeout depends entirely on the clock speed, it's double the duration at 12.5MHz than it is at 25MHz for example. So reduction of clock here is just extending the absolute timeout period to match what your (slow) card needs. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkjKLyYACgkQOjLpvpq7dMq43wCbBPyb/SyE1mROkhkKYK6csbKM Qf8An3NzhubMZmuEMozI0vBme1LZks9J =iz// -----END PGP SIGNATURE----- _______________________________________________ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support
