DMA problem: Insufficient memory[-] bulk transfer error

[EmhyrVarEmreis]

I have a problem using my screamer (PCIe Squirrel).

Target hw:
i9-13900K
ASUS PRIME Z790-P
ASUS RTX 4090
VT-d disabled

Pcileech running hw:
Rpi5 (ubuntu, self compiled pcileech) / asus laptop win11

Case No2 seems to work for a few seconds and after that I am getting this Insufficient memory. After that resetting screamer does not work until I restart target pc. What can cause that error?

[ufrisk]

probing is super aggressive and you can try to dump memory instead, i.e. with ./pcileech dump -out none -device fpga -v to see if things improve.

possibly also use a memory map

Please let me know if this was sufficient to resolve your issue.

The error looks kinda bad anyway so I'm not sure it will resolve the issue. Its an error with libusb usb transfers. Also make sure to use the latest download of pcileech when you try this.

If its still around I don't have access to a RPI5 right now I'm afraid. It's on my purchase list though :)

[EmhyrVarEmreis]

It is much better, now it reached 97% with dump.
After this error (and previous ones) I got PCILEECH: Failed to connect to the device. next time launching pcileech until I restart target PC.

I will check if mount with MemProcFS mount will be stable

Is there a way to reduce speeed of the process?

[ufrisk]

You can try to add -device fpga://algo=2 and retry, maybe it will be more stable (but also a bit slower unfortunately, but if it works the speed will still be decent.

There are some additional parameters that can be used on conjunction with fpga://algo=2, for more info about those have a look here: https://github.com/ufrisk/LeechCore/wiki/Device_FPGA Mainly tmread, tmwrite will be of interest.
