Odp: Linki do portów szeregowych - problem po restarcie

Stabilny to jest 15.05 r46767, który np. używa kernela w dużo starszej wersji niż Cezarowe r48749. No chyba, że on aplikuje tylko niektóre zmiany. Nieważne, zaraz ściągnę snapshot...

A jednak nie ściągnę, bo jest tam zwyczajnie pusto. Mogę skompilować, ale to już chyba dopiero jutro.

Buduję z aktualnych źródeł CC, a tam jest nawet już daleko dalej niż r48749. To jest przyszłe 15.05.1

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

Z tym "w dużo starszej wersji" przesadziłeś smile Całe wydanie CC bazuje na kernelu 3.18.

Eh, jeszcze nie wrzucili po awarii dysków.

@Cezary
Hmm... czyli te wszystkie oficjalne poprawki to tak napradę backporty?

@pepe2k
3.18.20-1 vs. 3.18.23-1 - ale masz rację, nieco przesadziłem tongue

Nie wszystkie, bo kernela nie zmieniają tylko podbijają ew numerek. Poprawki bezpieczeństwa, jakieś łątki na architekturę, bardzo niechętnie dodają nowe urządzenia. Ale np. na dniach cały mac80211 został zaktualizowany i zsynchronizowany z trunkiem.

Hmm.. skopilowałem ze źródeł DESIGNATED DRIVER (Bleeding Edge, r48917), obraz wrzuciłem do gl-neta no i zorientowałem się, że zapomniałem o dodatkowych pakietach. Szybko odpaliłem make menuconfig, zaznaczyłem wszystkie braki jako moduły, zapisałem konfigurację i _bez_ czyszczenia katalogów ponownie zrobiłem make. Po minutce miałem już brakujące pakiety tj.

kmod-usb-serial_4.1.16-1_ar71xx.ipk
kmod-usb-serial-pl2303_4.1.16-1_ar71xx.ipk
usbreset_4_ar71xx.ipk
usbutils_007-1_ar71xx.ipk

Wrzuciłem jest do /tmp pudełka, próbuję zainstalować i:

root@OpenWrt:/tmp# opkg install kmod-usb-serial_4.1.16-1_ar71xx.ipk
Installing kmod-usb-serial (4.1.16-1) to root...
Collected errors:
 * satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-usb-serial:
 *     kernel (= 4.1.16-1-cd528e51a7f3dfa3124b4e3684bd3313) * 
 * opkg_install_cmd: Cannot install package kmod-usb-serial.

Czy to wina tego, że nie zrobiłem clean? Nie bardzo rozumiem jak mogłem nie spełnić zależności, skoro wszystko jest kompilowane z tych samych źródeł hmm

Moduły masz zainstalować z tego samego momentu co kernel. Więc zaznacz co chcesz, skompiluj i instaluj system i swoje moduły,

Ok, wystarczylo make target/linux/clean i ponowna, szybka kompilacja. Na trunku jest praktycznie tak samo:
