init TypeError:

[Lennox7746]

Hello，when i running the example code ,it tell me :

vmm = memprocfs.Vmm(['-device', 'C:/Dumps/WIN10-X64-1909-18363-1.mem']) Traceback (most recent call last): File "", line 1, in TypeError: Vmm.init(): Initialization of vmm failed.

How can i do for this? My systerm is win11 and the cpu is AMD R7 7840HS. Hope the solution,thanks !

Hi,

This API call tries to initialize using a memory dump file named: C:/Dumps/WIN10-X64-1909-18363-1.mem.

Since you mention your system I'm assuming you wish to target the FPGA. That would be:

vmm = memprocfs.Vmm(['-device', 'fpga'])

or you may have to use a memory map as well:

vmm = memprocfs.Vmm(['-device', 'fpga', '-memmap', 'C:\\Path\\To\\My\\memmap.txt'])

Please let me know how this goes and if the issue is resolved (then close this issue).

And best wishes with your Python DMA project :)

I know the reason, my mother board is AMD,when i come home, I use the computer which mother board is AMD too ( A320-pro), it not work yet,but now, I'm in my friend's home and use his computer that mother board is Intel ( Z690 ) , the same DMA board is working well，I think I have to buy a intel mother board for using DMA board............

If you're on AMD just use the memory map approach as I linked to in the above post and things will be fine. No need to purchase new hardware.

I'm sorry sir,I don't find the link about AMD, can you give me the link in the comment ? Thanks !

And I have a question, according to the pictures in the project, my board should be LeetDMA, but I cannot find the corresponding FPGA project for LeetDMA. May I ask which FPGA project corresponds to LeetDMA?

[ufrisk]

LeetDMA is compatible with the PCIeSquirrel FPGA bitstream/project.

OK, get it .Thank you very much !
