I recently bought 2 more TE0715 modules and couldn't get the ethernet working.   When I probe U9, which is the XTAL_IN to the Marvell 88E1512 chip it measures 33MHz.    I have another module that the ethernet does work and the frequency measures 25MHz.     The frequency to the chip should be 25MHz.

Hi,
can you send me the serial numbers of the two modules to support@trenz-electronic.de

Hi,
we have done a recall for this production batch of TE0715. Maybe this was not forward to you from the distributor.

So please send a email to support@trenz-electronic.de
