ROCKPro64 - PCIe x4

[FrankM]

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

Update: Leuchte auf der PCIe-Karte ist AN

[FrankM]

Leider kackt der Kernel jetzt mit der NVMe-Karte ab

Mal auf Kamil warten und schauen was er dazu sagt.

[FrankM]

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

Linux-Version:

rock64@rockpro64:~$ uname -a

Linux rockpro64 4.4.126-rockchip-ayufan-253 #1 SMP Mon Jun 4 08:47:16 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux

lspci

rock64@rockpro64:~$ lspci
00:00.0 PCI bridge: Rockchip Inc. RK3399 PCI Express Root Port Device 0100
01:00.0 SATA controller: ASMedia Technology Inc. ASM1062 Serial ATA Controller (rev 02)

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

Ok, das Ding bootet sauber. Die Spannungen scheinen immer noch nicht sauber geschaltet zu werden.

lspci gibt das hier aus

pcilib: Cannot open /sys/bus/pci/devices/0000:00:00.0/config
lspci: Unable to read the standard configuration space header of device 0000:00:00.0

Meine Recherche im Internet ergab, das es wohl an fehlenden/falschen Kerneloptionen liegt. Ok, da bin ich raus

Zusatzbemerkung: Aktuell 6 Watt Stromaufnahme.

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 out

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

[FrankM]

Und schwupps ist ein neuer Mainline da.

Stark schwankend!??

	LnkSta:	Speed 5GT/s, Width x2

Aber, das passt jetzt!

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

[FrankM]

Als Ergänzung, die Probleme sind zum großen Teil gefixt. Wir haben mittlerweile x4

Booten geht einwandfrei, einziges Problem im Moment. Es gehen nur sehr wenige Karten.

Hi
ist es eigentlich möglich an diesem port ein dedizierte Grafikkarte zu betreiben? eventuell mit einem mining PCiEpress adapter zur Strom versorgung?

@Northstar Hallo, laut meinen Info's nicht, hat irgendwas mit der Speicheradressierung zu tuen. Und Grafikkarten benötigen wohl zu viel. Das ist das, was ich bei den vielen Diskussionen im IRC so aufgeschnappt habe.

Ich habe es auch schon mal genauso probiert - natürlich ohne Erfolg.
