Hallo borg, habe die neue Firmware einmal ausprobiert. Der USB Master brick wird nun erkannt, wenn ich die Spannung einschalte. pi@raspberrypi ~/dev $ sudo dmesg -c [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Initializing cgroup subsys cpuacct [ 0.000000] Linux version 3.18.7+ (dc4@dc4-XPS13-9333) (gcc version 4.8.3 20140303 (prerelease) (crosstool-NG linaro-1.13.1+bzr2650 - Linaro GCC 2014.03) ) #755 PREEMPT Thu Feb 12 17:14:31 GMT 2015 [ 0.000000] CPU: ARMv6-compatible processor [410fb767] revision 7 (ARMv7), cr=00c5387d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT nonaliasing instruction cache [ 0.000000] Machine model: Raspberry Pi Model B+ [ 0.000000] cma: Reserved 8 MiB at 0x1b800000 [ 0.000000] Memory policy: Data cache writeback [ 0.000000] On node 0 totalpages: 114688 [ 0.000000] free_area_init_node: node 0, pgdat c084d804, node_mem_map db474000 [ 0.000000] Normal zone: 896 pages used for memmap [ 0.000000] Normal zone: 0 pages reserved [ 0.000000] Normal zone: 114688 pages, LIFO batch:31 [ 0.000000] pcpu-alloc: s0 r0 d32768 u32768 alloc=1*32768 [ 0.000000] pcpu-alloc: [0] 0 [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.

Muss ja dann noch ein Problem mit dem BrickDeamon sein, oder? Edit: hab jetzt erstmal wieder die alte Firmware geladen und ne Brücke über D11 gelötet, dann gehts auch.

Ja das beschreibt mein Szenario exakt. (-: Ich habe mir gerade einmal die 5V des Step Down Power Supply und die eines USB Port des Raspberry beim Einschalten angeschaut. Mein Raspberry braucht 4,6 Sekunden, bis er die USB Versorgung einschaltet. @Gruenauge: Welche Firmware hast du den auf deinem Master Bricks? Auf meinen ist 2.3.1. 20150318-0007.pdf

Hm... das ist ja schade. Ich hab nen ziehmlich großen Aufbau, daher reicht die Spannungsversorgung über usb nicht aus. Es soll ein Testaufbau werden, den man nur einschalten braucht und der dann loslaufen soll. Daher ist das mit dem jedes mal Reset Taster drücken ungünstig. Anfangs hatte ich den Stapel per USB an meinen PC angeschlossen, aber als ich dann immer mehr Bricklets angschlossen habe war irgendwann war dann der Strom zu groß und der Port überlastet. Um mein Problem zu lösen habe ich aktuell folgende Ideen: a) ein Kabel an den Reset löten und mit einem GPIO vom Raspi verbinden und dann nach dem Hochlauf des Raspi einen Reset auslösen. oder b) FB4 auf dem untersten Modul runterlöten, sodass mein unterstes Modul nur über USB versorgt wird. @Borg: Was hälst du davon?

Ich habe bei mir mit folgender Konfiguration USB Probleme: 1x Power Supply(zur Versorgung des Raspberrys über GPIO und um den Stapel zu versorgen) 7x USB Bricks Der Power Supply ist ist ganz unten im Stapel. Das Usb Kabel geht vom untersten usb Brick zum Raspberry. Wenn ich bei dem System die Spannung einschalte, dann sehe ich im Brick viewer keine Module und auch dmesg zeigt mir keine USB verbindung an. pi@raspberrypi ~ $ sudo dmesg -c [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Initializing cgroup subsys cpuacct [ 0.000000] Linux version 3.18.7+ (dc4@dc4-XPS13-9333) (gcc version 4.8.3 20140303 (prerelease) (crosstool-NG linaro-1.13.1+bzr2650 - Linaro GCC 2014.03) ) #755 PREEMPT Thu Feb 12 17:14:31 GMT 2015 [ 0.000000] CPU: ARMv6-compatible processor [410fb767] revision 7 (ARMv7), cr=00c5387d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT nonaliasing instruction cache [ 0.000000] Machine model: Raspberry Pi Model B+ [ 0.000000] cma: Reserved 8 MiB at 0x1b800000 [ 0.000000] Memory policy: Data cache writeback [ 0.000000] On node 0 totalpages: 114688 [ 0.000000] free_area_init_node: node 0, pgdat c084d804, node_mem_map db474000 [ 0.000000] Normal zone: 896 pages used for memmap [ 0.000000] Normal zone: 0 pages reserved [ 0.000000] Normal zone: 114688 pages, LIFO batch:31 [ 0.000000] pcpu-alloc: s0 r0 d32768 u32768 alloc=1*32768 [ 0.000000] pcpu-alloc: [0] 0 [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.
