LTE module added to wAP R AC blocks system booting

[ttrabatt]

Hello

we have bought wAP R AC by mistake w/o LTE module, then we bought LTE modules (R11eL-EC200A-EU with Chipset QUECTEL).
With the LTE module installed the wAP R don’t even complete boot, it cycles USR led ON, fast blinking of both ethernet green leds, USR led off.
If I remove the LTE module the wAP R AC boots correctly with all releases tested.

Tested with 7.15.2 and also 6.49.15, with SIM inserted or not.
Tried Netinstall of 7.15.2 same result
Since it does not boot I can’t download the supout.rif file for further analysis.
I only have the supout.rif file when the LTE module is not installed, but clearly not very significant[/list][/list]

Any idea how to solve the issue?
Many Thanks in advance and Best Regards

Hello

Problem solved on Arits Bernāts. Problem due to new LTE module which do require some HW patching.
Tested on multiple wAP R AC successfully

You need to tape/isolate mini-PCIe PERST pin #22
