Hi Ty, Please tell:) What approach did you use to create the pci Device after boot?
Thanks, Dave:) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, October 06, 2004 1:52 PM To: Jay Miller Cc: Ronald G. Minnich; YhLu; [EMAIL PROTECTED] Subject: Re: Adding a PCI device that doesn't exist (yet) Hopping in mid-thread here so I may have the context wrong: I have succeeded at programming the FPGA to create a PCI device after the boot process. I was then able to have the device driver add the device to the pci device table and get resources allocated for it and get it paired up with the alread loaded device driver. I did not figure out how to de-allocate/de-register such that I could cleanely re-program the FPGA without a re-boot. Is this relevant? Cheers! Ty Jay Miller wrote: > Thanks for your help.
