Before going any further into the description, here I am describing the problems related to the bare module, not the Evaluation board, I do only have the module itself.
I have an EM9191 module, brand-new, I just took it out of the package and installed it directly into an M2 socket B, however, the module did not show up.
Then I used a USB adapter, which, of course, failed again.
I understand the module is by default in PCIe mode, please can someone confirm?
Another key point, does the module requires a specific type of M2 socket B? I just read that the module requires a PCIe 3.0 compatible interface to work ‘properly’ , but I have no clue what kind of M2 interface I got, I just know that it’s a key B, can this be the root cause of the problem?
I read about this PIN, but I don’t have access to any other interface than M2, and unless that PIN is somewhere available in the module itself (not in the development board) I don’t have any means to change it, or maybe I am missing something?
Ehm, do you mean to somehow connect to the contact number 20 of the M2 socket that contains about 60 pins? That sounds quite hard to achieve without special equipment, at least I have no idea how to do that without actually soldering something to the board… is that what you meant?
Hmmm… that’s tough to do really, it is an embedded system that has many other things running at the same time, so … I don’t have any means to directly measure the current.
Maybe, I should get myself a Development Board … or, can you point me to an USB adapter that has been tested and it is compatible with the module please? , I think though, this adapter must have a way to indicate (thru pin 20) that it is on USB Mode, is that possible?
