ROCKPro64 - PCIe x4



  • Einer der spannendsten Anschlüsse auf dem SOC ist für mich die PCIe x4 Schnittstelle.

    0_1526561543169_pcie.jpg

    Diese PCI Express Schnittstelle verfügt über 4 Lanes.

    Diese ermöglichen es, direkte Verbindungen zwischen einzelnen PCIe-Geräten herzustellen, so dass die Kommunikation einzelner Geräte untereinander die erreichbare Datenrate anderer Geräte nicht beeinflusst.

    Das verspricht ausreichend Geschwindigkeit. Aber bis dahin ist es noch ein langer Weg, brauchen wir ja erst mal ein funktionierendes Linux. Aber, das wird. Kenne da einen Polen, der schon ganz nervös ist 🙂

    Was kann man nun in diesen Slot einstecken? Die Fa. Pine64 bietet zwei Steckkarten an.

    PCIe Steckkarte Dual-SATA

    0_1526562395318_pcie_sata2.jpg

    Diese Karte bieten uns also zwei interne STAT-II-Anschlüsse und zwei externe eSATA-Anschlüsse an.

    Das jetzt ist eine Vermutung von mir und nicht bestätigt.
    Von diese vier Anschlüssen können aber nur zwei gleichzeitig benutzt werden. Zum Auswählen der Anschlüsse befinden sich auf der Karte Jumper.

    Transferrate bei SATA-II sind bis zu 300 MByte/s möglich.

    PCIe Steckkarte M.2

    0_1526563063720_pcie_m2.jpg

    Yes, da bin ich wirklich sehr gespannt drauf. Eine SSD Interfacekarte auf der man einfach eine Samsung 960 EVO M.2 schrauben kann.

    0_1526563221074_960evo.jpg

    Das sieht dann so aus ☺

    Die Werbung von Samsung verspricht 3200MB/s lesend und 1900MB/s schreibend. Dafür könnte sich die PCIe-Schnittstelle richtig lohnen. Aber warten wir es ab, das wird wohl noch was dauern bis man dazu eine fundierte Antwort geben kann.

    Dazu gibt es auch schon eine interessante Diskussion, die auch auf unser SOC 3399 eingeht. https://forum.armbian.com/topic/1925-some-storage-benchmarks-on-sbcs/?tab=comments#comment-54018

    Lassen wir uns überraschen 😉



  • Bis jetzt funktioniert das PCIe in den aktuellen Boards noch nicht.

    Aufpassen, wir haben hier ganz taufrische Boards auch Preproduction genannt in den Händen.

    Wir sind dafür da, die Fehler auszubügeln. 😉

    Es sieht wohl so aus, das die 3,3V irgendwie die Karte nicht erreichen. Man hat aber in der Technik nach dem Fehler gesucht und auch gefunden. Es scheint so zu sein, das ein Widerstand im Weg rum steht. Soll sich aber lösen lassen.

    Hier ein Video aus der technischen Abteilung, der zeigt das der Bus funktioniert.

    Ach so, hatte ich schon erwähnt, das die Unternehmenskommunikation mit ihren Kunden und Entwicklern bis jetzt 1A ist?

    Ich weiß welcher Widerstand, aber ich trau mich nicht ....



  • Bin jetzt bei einem Fachmann, Mal hoffen das das Ding danach noch lebt 😀

    Update: Leuchte auf der PCIe-Karte ist AN 😀



  • Leider kackt der Kernel jetzt mit der NVMe-Karte ab 😞

    Mal auf Kamil warten und schauen was er dazu sagt.



  • So, nachdem Lukasz geschrieben hat das seine SATA-Karte mit zwei HDD's funktioniert habe ich mich nochmal ran gemacht.

    Ok, ich sehe die PCI Brücke und meinen Adapter der an einem externen eSATA Port angeschlossen ist.

    Meine Aussage aus dem Eingangspost

    Das jetzt ist eine Vermutung von mir und nicht bestätigt.
    Von diese vier Anschlüssen können aber nur zwei gleichzeitig benutzt werden. Zum Auswählen der Anschlüsse befinden sich auf der Karte Jumper.

    kann ich bestätigen. Vorher wurde nichts angezeigt, erst als ich die Jumoer auf extern umgestellt hatte!

    Leider sehe ich die SSD nicht und weiß im Moment an dieser Stelle auch nicht weiter. Noch die entsprechenden Einträge aus dmesg

    Kurz mal die Platte eingerichtet und formatiert. Kurzer Speedtest

    rock64@rockpro64:/mnt$ sudo dd if=/dev/zero of=sd.img bs=1M count=4096 conv=fdatasync
    4096+0 records in
    4096+0 records out
    4294967296 bytes (4.3 GB, 4.0 GiB) copied, 11.795 s, 364 MB/s
    

    Ganz zufrieden sind wir noch nicht. Die Platte ist nur mit 2 Lanes angeschlossen (x2) müsste aber eigentlich x4 sein. Wäre dann theoretisch doppelte Geschwindigkeit.

    LnkSta:	Speed 5GT/s, Width x2, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-
    

    Aber, der Kamil macht das. Da bin ich mir sicher. Und ich weiß, das das Entfernen des Widerstandes das Richtige war.

    Yeah, ein netter Erfolg!! DANKE Kamil!

    Der Grund müsste das hier sein.

    LnkSta:	Speed 2.5GT/s
    

    Das ist beim 4.4er auf 5GT/s. Ok, ich habe aber schon gesehen, das Kamil da was entsprechendes schon geändert hat, könnte also im nächsten Mainline schon anders sein.

    Was mich jetzt aber interessiert, warum geht das auf einmal!?? Da scheint noch einiges völlig instabil zu sein 🤔



  • Und schwupps ist ein neuer Mainline da.

    Aber, das passt jetzt!

    Übrigens, muss ich ab und zu mehrmals booten bevor ich PCIe habe???
