Hello
I set up VMware according to this guide https://docs.sel4.systems/Hardware/VMware/ (using serial output to file) and compiled the picoserver CAmkES application (for x86_64) to run inside the VMware machine.
However, I do encounter a seL4_FailedLookup error. I understand the error message but cannot figure out why it occurs nor how to fix it (probably my pci configuration is wrong). Attached you find the serial_output file.
For the ethernet configuration I used linux in the same VM to figure out the details:
1) ip addr: 2: ens32: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000 link/ether 00:0c:29:90:a7:4a brd ff:ff:ff:ff:ff:ff

And here the configuration part inside picoserver.camkes (anything else NOT pasted here is unmodified):
picoserver.ethdriver_mac = [0x00, 0x0c, 0x29, 0x90, 0xa7, 0x4a];
....
hwethdriver.mmio_paddr = 0xfd500000 hwethdriver.mmio_size = 0x10000 hwethdriver.irq_irq_type = "pci"; hwethdriver.irq_irq_ioapic = 0; hwethdriver.irq_irq_ioapic_pin = 18; hwethdriver.irq_irq_vector = 18;
ethdriver.iospaces = "0x0:0x02:0x00:0"; ethdriver.iospace_id = 0x0200; ethdriver.pci_bdf = "0x02:0x00.0";
I am sorry to bother you with this; I am fairly new to low level stuff. Any help would be very much appreciated.
Best regards,
Benjamin
