[spark] decode HDMI EDID

[graugans]

Ich habe mal ein bisschen mit den edid Informationen meiner Golden Media Spark Triplex rumgespielt. Dazu habe ich die sourcen von edid-decode so angepasst, dass die die Ausgabe von

Code: Alles auswählen

/sys/devices/virtual/stmcoredisplay/display0/hdmi0.0/edid

verarbeiten kann. Leider funktioniert das ganze nicht mit den mir bekannten Fulan spark 7111 Boxen, da die einen H/W Bug haben.

Das ganze sieht dann wie folgt aus:

Leider funktioniert das ganze nicht mit den mir bekannten Fulan spark 7111 Boxen, da die einen H/W Bug haben.

Schaut auf meinem Pingulux (also 7111) wider Erwarten auch ganz passabel aus. Außer, dass am Ende eine Fehlermeldung kommt, ist's Deinem Output vom 7162 schon ziemlich ähnlich:

Danke!

Interessant. Ich bin bis jetzt davon ausgegangen, dass die Spark 7111 Boxen nen Hardware-Bug haben. Eventuell ist das bei den Pingulux Boxen nicht so. Ich werde das bei meiner GM 990 aufjeden Fall nochmal an einem anderen Schirm testen.
