Quecopen EC20 GPRS functionality with SDK API's


I have been working with Quecopen SDK : EC20CEFILGR06A04M1G_OCPU.

  1. To establish the GPRS functionality, we have integrated QL_WWAN API’s, as per SDK examples in my application. While running the application manually, GPRS functionality is working fine. But the same application, GPRS is not working, when it run’s from auto start up.
  2. Can you please suggest, How to decrease CPU clock speed in Quecopen linux.
    Please help me with that.


Hi @Bhagavan

could you provided some logs for Q1, so it will be helpful
and for Q2, please try to modify clock_cpu node in mdm9607.dtsi.
