Hi all,
Having a real difficult time determining whether or not I can use qemu (arm) with the Sabrelite machine type to be able to assign an sd-card to one of the 4 available sd-bus slots. Currently, no matter what combination of arguments I provide,
it will always fall on the first bus (see screenshot).
Is there any way with QEMU to attach the card specifically to the last sd-bus slot? It should be noted I was able to achieve the expected behavior after patching QEMU itself with the following change but I’d prefer to not have to modify
the tool itself.
diff qemu-5.1.0.orig/hw/sd/sdhci.c qemu-5.1.0/hw/sd/sdhci.c
1311a1312,1314
> static int index=0;
> char name[64];
> sprintf(name, "sd-bus.%d", index++);
1313c1316
< TYPE_SDHCI_BUS, DEVICE(s), "sd-bus");
---
> TYPE_SDHCI_BUS, DEVICE(s), name);
The above change allows you to then launch with the following arguments:
-drive file=sdcard.img,format=raw,id=mycard -device sd-card,drive=mycard,bus=sd-bus.0
