Yes, it is possible. The approach depends on which device is to be the bus master. If the StrongARM is to be the bus master, it needs to know the physical bus address of the target location. If the other device (disk controller) is to be the bus master, it needs to know the physical bus address of the target memory on the StrongARM. In either case, you will need to familiarize yourself with the PCI bus, the mapping registers on the StrongARM, and the disk controller device driver. Unfortunately, there is no set of functions or a simple recipe I can give for doing this. Scott On Thu, Jul 03, 2003 at 01:30:47PM +0900, Cho, joon-woo wrote:
Hello.
I installed IXP1200EB on the Linux machine with vera driver.
And I want to send a command from IXP1200EB to another device.
(Especially, SCSI controller or IDE HDD for DMA data transfer from there to
IXP1200 SDRAM unti)
Is it possible? And if possible, please let me know how I can.
Thanks.
