lapawa Geschrieben December 28, 2020 at 19:29 Geschrieben December 28, 2020 at 19:29 (bearbeitet) Hallo, derzeit bin ich dabei per buildroot (https://buildroot.org/) ein Embedded Linux Image für den Raspberry Pi Zero zu bauen. Das Image wird sehr minimalistisch und erstmal nur brickd beinhalten. Die eigentliche Applikation wird remote gestartet. Für die Anschlüsse der Bricklets verwende ich Tinkerforge HAT Zero 1.0 und einen RPi Zero mit USB Ethernet Schnittstelle. Wenn ich brickd starte, bekomme ich in einer rasenden Geschwindigkeit immer wieder diese Fehlermeldung: Quote <E> <bricklet_stack.c:506> Message packet error (port: E, count: 1), invalid response: Invalid UID Wie kommt es zu diesen Meldungen? Was kann ich tun? Ist Port E der Port vom HAT selbst? Denn Bricklet Anschlüsse hat das HAT Zero nur vier, also bis Port D. Besten Gruß und vielen Dank für jegliche Hilfe. So sieht die brickd.conf aus (grep -v \# /etc/brickd.conf|sort): Quote authentication.secret = bricklet.group0.cs0.driver = gpio bricklet.group0.cs0.name = gpio27 bricklet.group0.cs0.num = 27

rtrbt Geschrieben January 4, 2021 at 08:38 Geschrieben January 4, 2021 at 08:38 Moin, Ja, Port E ist der vom HAT selbst. Das Problem, dass du da hast scheint ein Bug in der aktuellen Version von Brick Daemon zu sein, ist z.B. hier schon mal aufgetaucht. @photron ist noch im Weihnachtsurlaub, aber in den nächsten Wochen fixen wir das. Edit: Als Work-Around kannst du auch probieren, ob Brick Daemon 2.4.1 bei dir das Problem nicht erzeugt. Der braucht aber udev oder ähnliches. Zitieren
lapawa Geschrieben January 4, 2021 at 19:13 Autor Geschrieben January 4, 2021 at 19:13 (bearbeitet) Die version 2.4.1 hat mir nur ein Stückchen weitergeholfen. Die Fehlermeldungen sind weg. Eine Verbindung per brickv funktioniert. Jedoch werden weder brick noch bricklets im brickv angezeigt. Diesmal habe ich zusätzlich zum Debug Log noch eine Strace Auszug erstelt. Was mir auffällt ist, dass brickd ständig write Zugriffe auf libusb ausführt. Und dies obwohl das HAT per SPI mit den Bricklets kommuniziert. dass die GPIO Exports beim Beenden von brickd nicht wieder beim Kernel abgemeldet werden. Zugriff auf die Zeitzonen datei /etc/localtime funktioniert nicht. Da sie nicht existiert. openat(AT_FDCWD, "/etc/localtime", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) Ist dies ein Problem für brickd? Das HAT wird erkannt: openat(AT_FDCWD, "/proc/device-tree/hat/product_id", O_RDONLY) = 17 read(17, "0x085d", 6) = 6 close(17) 2021-01-04 18:35:46.490397 <D> <bricklet.c:182> Found product_id "0x085d" in device tree, using pre-configured HAT Zero Brick setup Die GPIOs für die Chip Select Signale der einzelnen Parts A-E werden beim Kernel als export angemeldet openat(AT_FDCWD, "/sys/class/gpio/export", O_WRONLY) = 18 write(18, "27", 2) = 2 close(18) = 0 openat(AT_FDCWD, "/sys/class/gpio/gpio27/direction", O_WRONLY) = 18 write(18, "out", 3) = 3 close(18) = 0 openat(AT_FDCWD, "/sys/class/gpio/gpio27/value", O_WRONLY) = 18 write(18, "1", 1) = 1 close(18) = 0 openat(AT_FDCWD, "/sys/class/gpio/gpio27/value", O_WRONLY) = 18 Meine Frage hierzu: Kann der Kernel SPI Treiber das CS Timing nicht besser selbst erledigen? Clock und MasterOut kommt ja auch von dort, oder?

lapawa Geschrieben January 5, 2021 at 12:46 Autor Geschrieben January 5, 2021 at 12:46 Ich habe noch ein paar Angaben zu den Taktfrequenzen des RPi Zero gesammelt: vcgencmd vchiq_test vcmailbox vconfig vcsmem # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq 1000000 # vcgencmd measure_clock arm frequency(48)=1000104000 # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor performance # vcgencmd measure_clock core frequency(1)=400000000 Zitieren
rtrbt Geschrieben January 6, 2021 at 10:25 Geschrieben January 6, 2021 at 10:25 Bezüglich der Taktfrequenzen: Brick Daemon bis einschließlich 2.4.2 erwartet eine core-Clock von 250 MHz (die die du mit vcgencmd measure_clock core ausgelesen hast). Beim Pi Zero kannst du die Frequenz mit core_freq=250 in /boot/config.txt festlegen. Die Umbauarbeiten in 2.4.2 und 2.4.3 sind genau dafür da solche Probleme zu umgehen, der Pi skaliert nämlich die SPI-Clock mit der core_freq, d.h. wenn er auf 400 MHz läuft, läuft SPI so schnell, dass die Bricklets das nicht mehr verstehen. On 1/4/2021 at 8:13 PM, lapawa said: dass brickd ständig write Zugriffe auf libusb ausführt. Und dies obwohl das HAT per SPI mit den Bricklets kommuniziert. Das liegt vermutlich daran, dass der Brick Daemon für den Pi auch Stacks per USB unterstützt. Das ist keine spezielle gestrippte Version, die nur SPI kann. On 1/4/2021 at 8:13 PM, lapawa said: dass die GPIO Exports beim Beenden von brickd nicht wieder beim Kernel abgemeldet werden. Das ist interessant, dazu muss ich @photron mal befragen. On 1/4/2021 at 8:13 PM, lapawa said: Zugriff auf die Zeitzonen datei /etc/localtime funktioniert nicht. Da sie nicht existiert. openat(AT_FDCWD, "/etc/localtime", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) Ist dies ein Problem für brickd? Das sollte kein Problem sein, du hast ja ein HAT Zero, das hat sowieso keine RTC an Bord. On 1/4/2021 at 8:13 PM, lapawa said: Meine Frage hierzu: Kann der Kernel SPI Treiber das CS Timing nicht besser selbst erledigen? Clock und MasterOut kommt ja auch von dort, oder? Nein, weil der Kernel nicht genug CS-Pins unterstützt. Meines Wissens nur zwei. Ab Brick Daemon 2.4.2 umgehen wir sowieso das ganze Kernel-Interface und sprechen direkt mit dem BCM2835. Zitieren
lapawa Geschrieben January 8, 2021 at 14:43 Autor Geschrieben January 8, 2021 at 14:43 Ein Wechsel auf 250MHz Core Frequenz hat bei beiden brickd ( v2.4.1 & v.2.4.3 ) nicht geholfen! Zitieren

Das war in 2.4.1 der Fall, das ist in 2.4.2 behoben und in 2.4.3 nicht mehr relevant, da dort die CS Pins im Normalfall nicht mehr durch sysfs gesteuert werden.

Das sollte kein Problem sein, du hast ja ein HAT Zero, das hat sowieso keine RTC an Bord. brickd selbst greift nicht auf diese Datei zu, das ist vermutlich irgendwas in glibc oder libusb. Das kannst du ignorieren. Ich glaube nicht, dass das hier mit dem "Message checksum error" Problem zusammenhängt, dass Superb hat, wie @rtrbt vermutet. On 1/4/2021 at 8:13 PM, lapawa said: Die version 2.4.1 hat mir nur ein Stückchen weitergeholfen. Die Fehlermeldungen sind weg. Eine Verbindung per brickv funktioniert. Jedoch werden weder brick noch bricklets im brickv angezeigt. brickd 2.4.1 meldet diese Fehler auf Debug Level, was standardmäßig nicht sichtbar ist. Die Debug Logauszüge sehen aber gut aus. Komisch. Komisch ist dann auch, dass es mit brickd 2.4.1 nicht hilft, die core Clock auf 250MHz zu setzen. Für brickd 2.4.3 ist das setzen von core_freq auf 250 nicht mehr notwendig, da diese Version mit abweichenden core Clock Frequenzen um gehen kann. Vielleicht ist die BCM2835 Library ein Problem, die wird in brickd 2.4.3 standardmäßig verwenden, in Zusammenhang mit deinem Custom Linux Builds ein Problem. Brickd 2.4.1 verwendet stattdessen spidev und sysfs. Teste mal bitte folgendes: Installiere wieder brickd 2.4.3 und setze in /etc/brickd.conf die bricklet.spi.driver Option auf spidev: bricklet.spi.driver = spidev Du solltest dann in der Logausgabe Using spidev backend for Bricklets (forced by config) anstelle von Using BCM2835 backend for Bricklets (Raspberry Pi detected) stehen. Hilft das? Wenn das nicht hilft, dann teste bitte mal mit einem Standard Raspbian und Standard brickd 2.4.3 anstelle deines Custom Linux Builds. Nicht das hier ein Hardwaredefekt an HAT oder Raspberry Pi vorliegt. Ist beides schon vorgekommen. Hast du noch ein anderes Raspberry Pi zur Hand u das testen zu können? Zitieren
photron Geschrieben January 11, 2021 at 13:44 Geschrieben January 11, 2021 at 13:44 Noch eine Frage: Hast du am HAT Zero Brick irgendetwas angeschlossen? Falls ja hilft es alles vom HAT abzustecken? Zitieren
lapawa Geschrieben January 11, 2021 at 16:49 Autor Geschrieben January 11, 2021 at 16:49 (bearbeitet) Besten Dank für deine Ausführungen. Du hast mich mit dem Hinweis auf die Hardware auf die Lösung gebracht! Auch mit einem auf einer anderen Hardware (RPi Zero W + Zero HAT )funktionierendem Raspbian Linux bekomme ich keine Bricklets angezeigt. Also muss es an der Hardware liegen. Mein Ethernet Adapter scheint das Problem zu verursachen. Ich verwende dieses Modell: https://www.waveshare.com/wiki/ETH/USB_HUB_HAT Schematics: https://www.waveshare.com/w/upload/0/08/ETH_USB_HUB_HAT.pdf Und obwohl das Platinchen einen USB Hub besitzt an dem auch der Ethernet Chip hängt, macht es mir Probleme mit den SPI Leitungen. Denn wenn ich den Layer entferne und einen anderen Ethernet USB Adapter anschließe funktioniert der brickd wie erwartet! Mein Stapel sieht so wie auf dem Bild aus. Das ist meine interim Lösung bis der 7polige Stecker am Master Brick verfügbar ist. Ein Stapel gleicher Art funktioniert in einem anderen Projekt ganz prima. bearbeitet January 12, 2021 at 06:35 von lapawa Zitieren
photron Geschrieben January 11, 2021 at 17:30 Geschrieben January 11, 2021 at 17:30 Der Schaltplan verwirrt mich. Von der Beschreibung des HATs her scheint der sich nur 5V und 3,3V vom Raspberry Pi Header zu holen. Ich bilde mir auch ein auf dem schwammigen Produktfoto Leiterbahnen zu diesen Pins laufen zu sehen. Die USB Kommunikation läuft dann über diese kleine Adapterplatine. Falls das wirklich so ist sollte das funktionieren können. 35 minutes ago, lapawa said: Mein Stapel sieht so wie auf dem Bild aus. Das ist meine interim Lösung bis der 7polige Stecker am Master Brick verfügbar ist. Der hat in einem anderen Projekt auch bereits funktioniert. Genau dieser Aufbau hat schon mal funktioniert, oder ein anderer Aufbau dieser Art? Was hat sich geändert? Hast du vielleicht das klassische Raspberry Pi Problem und du versorgst den Aufbau nicht gut genug mit 5V? Zitieren
lapawa Geschrieben January 12, 2021 at 06:43 Autor Geschrieben January 12, 2021 at 06:43 Ich habe es mal umformuliert: "Ein Stapel gleicher Art funktioniert in einem anderen Projekt ganz prima." Die Stromvesorgung ist es nicht. Testweise versorge ich den Stapel mit einem kurzen Kabel (10cm) am 5V Ausgang eines Step-Down Power Supply. Dieser meldet mir per brickv eine Stromaufnahme von 230mA. Die USB/Eth Adapterplatine funktioniert sogar ohne RPi Header. Ich habe sie testweise nur mit einem USB Kabel verbunden und weit weg vom RPi betrieben. USB Hub und Ethernet funktionieren bei diesem Aufbau. Das Zero HAT jedoch nicht! Die Fehlemeldungen vom brickd variieren auch. Ein paar Beispiele: Quote 2021-01-11 17:56:35.711223 <E> <bricklet_stack.c:396> Frame error (port: A, count: 997) 2021-01-11 17:56:36.215338 <E> <bricklet_stack.c:396> Frame error (port: B, count: 196) 2021-01-11 19:00:51.379807 <E> <bricklet_stack.c:478> Message checksum error (port: B, count: 1) 2021-01-11 19:00:51.421364 <E> <bricklet_stack.c:431> ACK checksum error (port: B, count: 1) 2021-01-11 19:00:51.360066 <E> <bricklet_stack.c:506> Message packet error (port: B, count: 9), invalid response: Invalid UID Zitieren
lapawa Geschrieben January 12, 2021 at 07:09 Autor Geschrieben January 12, 2021 at 07:09 (bearbeitet) Nochmal einen Schritt zurück bitte. Als Referenzaufbau habe ich einen RPiZero WLAN mit Zero HAT und regulärem Raspbian 10 und brickd-2.4.3 aus dem deb Paket verwendet. Also der einfachste denkbare Aufbau, ohne USB/Ethernet HAT zwischen Zero HAT und Raspberry Pi. Komplett andere Hardware. Sogar ein zweites Zero HAT. Konzentrieren wir uns besser auf diesen Aufbau.

lapawa Geschrieben January 12, 2021 at 09:51 Autor Geschrieben January 12, 2021 at 09:51 Finally solved! Es war ein reines Problem mit der Hardware. Hier wurde mit zu viel Lötzinn gearbeitet. Durch das ETH/USB HAT wurde ausgerechnet Pin 17+21 also SPI-MISO und SPI-MOSI gebrückt! Siehe Bild: Also Klecks entfernt und alles ist wieder gut! Danke für die rege Teilnahme an der Problemlösung. Endlich kann es mit dem Projekt weitergehen. Ich freue mich auf einen Master Brick mit 7poligem Stecker. Die sind wenigstens auf Funktion geprüft und ersparen mir zeitraubenden Fehlersuchen dieser Art. Zitieren
