to Comedi: Linux Control and Measurement Device Interface
Hi.
I am writing a pci driver for adlink 9116 cPCI card. The card is very
simmilar to PCI 9118 already supported in comedi (the amcc chip
handles bus mastering)
The card has 3 bars registered as i/o ports.
Bar 0 is for accessing the operation registers of the chip that
handles the bus mastering.
Bar 1 is for registers that concern the data acquisition process.
I can not inl/outl to bar 1. Kernel freezes and a hard reboot is
needed. Because this kept happening I tested the card with the driver
provided for windows.
I installed linux again and made some modifications to the code. I
tried to run it and for the first time everything was ok.
Untill I rebooted. Than the same thing all over again.
Any ideas?
