Sourcecode Fortschritt
-
Rev. 401:
modul usb_hc.h/c geschaffen, um pci.c weiter zu "verschlanken".
-
Rev. 402:
- Rechtschreibfehler beseitigt (thx to +gjm+)
- auskommentierten Code in pci.c gestrichen
-
Rev. 403:
- void usbTransferSetConfiguration(uint32_t device, uint32_t configuration);
- uint8_t usbTransferGetConfiguration(uint32_t device);
- endpoint aus der Parameterliste der usb-Funktionen genommen, wenn sinnlos (z.B. wenn endpoint=0)Test bezüglich Konfigurationen (code auszugsweise):
abfragen, auf 2 setzen, abfragen, auf 1 setzen, abfragenif (USBtransferFlag && enabledPortFlag && (pOpRegs->PORTSC[j] & (PSTS_POWERON | PSTS_ENABLED | PSTS_CONNECTED))) { uint8_t devAddr = usbTransferEnumerate(j); usbTransferDevice(devAddr); // device address, endpoint=0 usbTransferConfig(devAddr); // device address, endpoint 0 usbTransferString(devAddr); // device address, endpoint 0 for(int k=1; k<4;k++) // fetch 3 strings { usbTransferStringUnicode(devAddr,k); } printf("\nconfig: %d",usbTransferGetConfiguration(devAddr)); usbTransferSetConfiguration(devAddr, 2); printf("\nconfig: %d",usbTransferGetConfiguration(devAddr)); usbTransferSetConfiguration(devAddr, 1); printf("\nconfig: %d",usbTransferGetConfiguration(devAddr)); }Anmerkung: Dieses printf("\n\n\n") ist leider notwendig weil die Konsole auch in den Info-Bereich schreibt.
-
Rev. 404:
- Kleine Korrektur: Konsolenbereich und Info area gegen einander geschützt (thx to MrX)
-
Revision 405:
- Infobereich ausgebaut: Fkt. writeInfo zum beschreiben, showInfo um festzulegen, ob der Infobereich in der Konsole angezeigt werden soll

Auch bei VMWare noch "timeout - no STS_USBINT set!"

Läuft z.Z. leider lediglich auf einem PC mit einem USB-Stick.
Ideen für Verbesserungen (aber leider noch nicht durchschlagend):
für read(10):
cbw->CBWFlags = 0x80; // Out: 0x00 In: 0x80 (anstelle "Out")memset(cbw,0,sizeof(struct usb2_CommandBlockWrapper)); // zero of cbw
DPO und FUA setzen:
Disable Page Out (DPO) allows the initiator to warn the target that the data being read is unlikely to be requested again soon and so is not worth keeping in the target's data cache. Force Unit Access (FUA) tells the target to fetch the data from the media surface and to not use a cached copy.
Evtl. auch Handshake-Problem, IN/OUT-Problem, toggle-Problem

rev. 416:
mit VMWare läuft diese Version
Wichtige Erkenntnisse: 1) handshakes stören 2) in SCSI: Big Endian!
Warum hardware damit noch nicht störungsfrei läuft, das liegt an qTD/QH.
-
rev. 417:
Version läuft mit VMWare, VBox, real PC. Erfolgreiche Übetragungen leider noch nicht überall.
Leider noch Fehlermeldungen, deren Ursache heraus gefunden werden muss.
a) USB-Interrupt kommt nicht (USB-Übertragung nicht vollständig)
b) halted - serious error (qTD status)
-
rev. 418:
leider spielt die wartezeit am ende von performAsyncScheduler() eine Rolle. Zu kurz oder zu lang führt zu "command failed" bei "test unit ready" bzw. zu einem nicht vollständigen USB-Transfer (kein USB-Interrupt). Ich habe jetzt mal auf 80 ms eingestellt.
Aber hier ist wohl ein Komplettumbau unseres async-Schedulers notwendig.
-
rev. 419: zwischenschritt: Umbau auf zwei QH (für den IN and OUT endpoint) mit jeweils angehängten qTD-Ketten.
