# B6 RAM-only modem lifecycle controller for Aurora (golden mm1). Lives in /tmp only.
|
|
# aurora-modem start | stop | status | addroute <ipv4>
|
|
# Reconstructs the proven flow (NOTES sessions 14-22 Aurora, JZ02 stopcycle/wwanfix/openrc):
|
|
# start: RO gates -> rmtfs -r -P -s -v (rmtfs -s starts MSS) -> MSS running -> wwan0qmi0+wwan0 (+2 s, JZ02 port-race guard)
|
|
# -> qmicli -p DMS online (one SET, only if not online) -> NAS registered + PS attached -> kill qmi-proxy
|
|
# -> udevd/dbus/polkitd/ModemManager -> MM modem registered -> ONE simple-connect -> bearer IPv4 on wwanN
|
|
# + /32 host routes only (no default route, usb0 untouched).
|
|
# stop: simple-disconnect -> MM disable (radio low-power = detach) -> del our /32 routes, flush+down all wwan* -> stop MM (+qmi-proxy) -> BAM-DMUX suspended
|
|
# -> SIGTERM rmtfs: rmtfs writes "stop" to remoteproc state (MSS stops while rmtfs still serves) -> rmtfs exits LAST.
|
|
# Never writes eMMC/NV: rmtfs -r keeps EFS writes in RAM; the script refuses to run unless the NV partitions are getro=1.
|
|
# Exit: 0 ok, 1 failure/timeout (start rolls back with a full stop unless MODEM_KEEP_ON_FAIL=1), 2 usage/config error.
