PCIe leech USB 3380EV can accessing the 64 bit address - This is Issue

[sridhaleech]

Hi ,

I'm doing the dumping certain memory ranges and in that covered 64 bit address also like " 0x100000000"

And able to do the 1 pages dumping with 64bit address range on PCI leech USB3380EV connected.

I have noticed that, there is a HW limitation from leech USB 3380EV and max address can be dump pages till 32 bit address range . like upto 0xffff ffff

But here i can dumping 1 page of 64 bit address, i'm not sure. Ideally its should not be dump 64 bit address range right ? pls refer the below dumping 1 page range ( 64 bit ranges )

C:\Users\CBRD\Desktop\pcileech_files>pcileech.exe dump -min 0x100000000 -max 0x100004000 -force

Current Action: Dumping Memory Access Mode: DMA (hardware only) Progress: 0 / 0 (100%) Speed: 4 kB/s Address: 0x0000000100000000 Pages read: 0 / 1 (0%) Pages failed: 1 (100%) Memory Dump: Successful.

Can you pls help me to clarify this ?

Thanks / Sridha

The text Memory Dump: Successful is misleading. It says 0 pages read and 1 pages failed (which is correct).

The usb3380 hardware do have a hardware limitation so it's not possible to read in the 64-bit ranges with it. To do that you'd need to get an FPGA device.

Thanks and still it is a issue from the leech USB3380EV card side ? if i'm not wrong .

even that "1 pages failed" also should not dump right ? Because 0x100000000 address is 64 bit and its should not dump 64 bit address by leech USB 3380 right ?

I'm looking for FPGA card for accessing 64 bit address ranges .

Yes, thanks for reporting. I'll change the message to Failed if all memory pages are failed.

I'm closing this issue due to old age.
