Karta szeregowa PCI nie będzie mówić w systemie Linux?


0

Używam Mageia Linux i mam kartę PCI z 2 portami szeregowymi, a moja płyta główna (ASUS H81M-A) nie ma wbudowanego portu szeregowego. Wygląda na to, że karta PCI jest produkowana przez WCH. Próbowałem zainstalować sterownik Linuksa dostarczony z kartą, ale mój system znalazł kilka błędów w plikach i przestałem instalować sterownik. Moja karta wygląda tak i ma bezpośrednio CH3825SP @ 1107. wprowadź opis zdjęcia tutaj

Zacząłem więc szukać pomocy online i znalazłem informacje, które można wykonać w następujący sposób.

Pobiegłem lspci -vi dostałem to. Myślę, że ten rozdział Serial controllerto moja karta szeregowa PCI.

Następnie uruchomiłem to polecenie, sudo setserial /dev/ttyS0 uart 16550Aaby ustawić Port ttyS0na kartę PCI. Zgodnie z postami na blogu ( Serial-Port-Work-Linux i elektronika FAQ ) znalazłem online, to wszystko, co muszę zrobić, aby korzystać z mojej szeregowej karty PCI. Jednak to nie działa. Po uruchomieniu setserialpolecenia mój program nie może uzyskać dostępu do ttyS0. Nie wiem, co robię ani jak to zrobić. Wszelkie wskazówki lub pomoc będą mile widziane.

AKTUALIZACJA Oto dmesg dla PCI. Przepraszam, jeśli to jest za długie. :)

Wygląda na to, że obsługa Twojej karty została ostatnio dodana w tym roku . Jeśli jądro jest wystarczająco nowe, powinieneś sprawdzić, czy moduł jądra jest załadowany

lsmod

jeśli nie, powinieneś go załadować

sudo modprobe serial_cs


Zobacz także dmesg / syslog po bootowaniu. modprobe, aby sprawdzić, czy sterownik rozpoznaje kartę lub czy występują jakiekolwiek problemy.
dirkt

Dowiedziałem się, że serial_cs nie został załadowany i załadowałem go przez modprobe. Znalazłem w Internecie najnowszy sterownik dla podobnej karty szeregowej PCI i udało mi się go pomyślnie zainstalować. Jednak stworzył własny PLIK szeregowy (ttyWCH01 i ttyWCH1) zamiast używać ttyS0 ... W każdym razie mój program nadal nie jest w stanie rozmawiać przez kartę PCI. Dodatkowo, mój program używa ttyS0 ... ttyS3 do połączenia.

@ dirkt Widziałem kilka linii związanych z PCI, ale nie mogłem stwierdzić, czy któryś z nich jest związany z moją kartą szeregową PCI.
ThN

Czy możesz gdzieś przesłać syslog / dmesg i opublikować link?

Ponadto, gdy tylko zadziała, dobrym pomysłem może być dodanie kilku udevreguł tworzących dowiązania symboliczne z logicznymi nazwami portów i zmiana programu na używanie ich zamiast ttyS0 ... ttyS3.
