Hi,
we use the LM7565 via an adapter in an miniPCIe interface. But it will always starts in Boot mode. What are the criterias to enter boot mode ? And how is it possible to switch to application mode ?
Appreciate your support,
Fabrice

sure. In Boot Mode the device has a different PID (0x9090) . In Application mode the PID is 0x9091.

Ok thats boot mode :-).
There are limited reasons as to why it would go into this mode.

The last point is the one I suspect. In the documentation (doc 4119652 rev 6) there is a section called “Power Ramp-up”. But there is not hint that the module enters Boot mode if some timings are not fullfiled.
Anyway. How can i switch to application mode ? In Boot mode there are two Bulk Endpoints (IN and OUT). Are there any commands that I can send via this interface ? Or are there certain USB requests to switch to the application mode ?

If the unit is in boot mode there is no way to cause/force/trigger it to go into its normal mode, it needs to do this of its own accord on power up, it has gone into boot mode because something is wrong.
