VME Block Transfer
I'm new to the VME bus and would be grateful if someone could provide
some guidance reguarding performing block transfers.
I'm using the following hardware
CPU : Radstone PPC7A5X - 7457 in slot 3
The board is using the Newbridge Universe VMEbus Interface. I have
looked through the VmeUniverse.h header file but can't see any
interface reguarding block transfers.
Re: VME Block Transfer
I think that board uses the Tundra Universe II pci to vme bridge I
think. Newbridge might second source it.
If you to you Radstone target directory (target/config/ppc7a), the
should be a subdirectory for ESP that has some VME DMA functions and
examples. If you don't have them, ask Radstone for them.
The ESP might be a separate BSP item that didn't come with your board.
Inititiating the DMA transfer should start the block transfer - you
should be able to get >30MB/second.
