Right now, Matthijs is mostly the one working on the current-gen Pyra and we haven't tested it extensively before shipping it to him. So the instability could be a faulty hardware. I'll ship out more prototype units next week (also a new one to Matthijs), so maybe it's just that. However, we have some weird behaviour with reboots and resets where some settings are being remembered, some aren't, etc., and we're currently investigating that. I don't think the EVM has these issues, but we're using different hardware for the power supply and a different DT-file, so it can't really be compared. -- Mit freundlichen Grüßen, Michael Mrozek ----------------------- OpenPandora GmbH Geschäftsführer: Michael Mrozek Schäffbräustr. 11 85049 Ingolstadt Deutschland Tel.: 0841 / 990 5548 http://www.openpandora.de/ HRB 4879, Amtsgericht Ingolstadt ----------------------- eMail: mrozek@xxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
