EC25

Below testing has been made on an EC25-E Revision: EC25EFAR02A03M4G (according to ATI0 and the label on the device)

serial console

In the EC25-E miniPCI that was analyzed, the serial console of bootloader and Linux appears to be active on pins 11+12 of the LGA module (DBG_RXD, DBG_TXD). The console is at 1.8V and at 115200bps.

processes

quectel_daemon

seems to be primarily concerned with voice routing / alsa codec related bits, including playback of ringtones

atfwd_daemon

implements Quectel specific extensions to the AT command interpreter (ATCOP) using the QMI framework to register them in the modem processor

Quec_WIFI_CLI

/usr/bin/time_daemon

/usr/bin/mbimd

/usr/bin/pdc_daemon

/usr/bin/diagrebootapp

an application registering a DIAG command with /dev/diag. Once that diag command is received, it will write to /dev/rebooterdev which will be picked up by reboot-daemon to actually do the reboot. Weird architecture.

/sbin/reboot-daemon

strange minimalistic daemon that does a blocking read on /dev/rebooterdev and issues a system("reboot") as soon as the read returns.

wlan_services

/usr/bin/qmi_ip_multiclient

eMBMs_TunnelingModule

something related to eMBMS (evolved=LTE Multicast)

alsaucm_test

/usr/bin/quectel-remotefs-service

  • uses /dev/smd8

/usr/bin/quectel_psm_aware

/usr/bin/quectel_monitor_daemon

  • reads from /sys/devices/4080000.qcom,mss/subsys1/quec_state

/usr/bin/quectel-gps-handle

  • uses /dev/ttyGS0 to print NMEA to host
  • uses /dev/smd7 to communicate with BB

/usr/bin/qmi_shutdown_modem

something low power mode related, uses qmi_simple_ril_test and data in /tmp/qmi-shutdown-modem/

/usr/bin/netmgrd

/usr/bin/thermal-engine

some kind of thermal management for the MSM SoC

/usr/bin/qmuxd

/usr/bin/quectel_pcm_daemon

related to alsa soc (asoc) codec configuration, uses /etc/auxpcm.conf

/usr/bin/qti

QCMAP_ConnectionManager

related to WLAN/WWAN back-haul switching

QCMAP_CLI

Program to configure QCMAP. Cnfiguration can also be done via web?
