{{>toc}} h1. EC25 Below testing has been made on an EC25-E Revision: EC25EFAR02A03M4G (according to ATI0 and the label on the device) h2. 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. h2. processes h3. quectel_daemon seems to be primarily concerned with voice routing / alsa codec related bits, including playback of ringtones h3. atfwd_daemon implements Quectel specific extensions to the AT command interpreter (ATCOP) using the QMI framework to register them in the modem processor h3. Quec_WIFI_CLI h3. /usr/bin/time_daemon h3. /usr/bin/mbimd h3. /usr/bin/pdc_daemon h3. /usr/bin/diagrebootapp an application registering a DIAG command to reboot Linux? h3. /sbin/reboot-daemon strange minimalistic daemon that does a blocking read on @/dev/rebootdev@ and issues a system("reboot") as soon as the read returns. h3. wlan_services h3. /usr/bin/qmi_ip_multiclient h3. eMBMs_TunnelingModule something related to eMBMS (evolved=LTE Multicast) h3. alsaucm_test h3. /usr/bin/quectel-remotefs-service h3. /usr/bin/quectel_psm_aware h3. /usr/bin/quectel_monitor_daemon h3. /usr/bin/quectel-gps-handle h3. /usr/bin/qmi_shutdown_modem h3. /usr/bin/netmgrd h3. /usr/bin/thermal-engine some kind of thermal management for the MSM SoC h3. /usr/bin/qmuxd h3. /usr/bin/quectel_pcm_daemon related to alsa soc (asoc) codec configuration, uses /etc/auxpcm.conf h3. /usr/bin/qti h3. QCMAP_ConnectionManager h3. ipacmdiag related to https://source.codeaurora.org/quic/la/platform/vendor/qcom-opensource/data-ipa-cfg-mgr/ ? h3. ipacm_perf related to https://source.codeaurora.org/quic/la/platform/vendor/qcom-opensource/data-ipa-cfg-mgr/ ? h3. psmd /dev/socket/psm h3. /sbin/adbd android debug bridge. h2. misc outputs h3. lsusb output <pre> Bus 001
