Hi Ameet, Today I tried the System ACE driver in interrupt mode. The driver is connected to the processor through IRQ4 .
So, in xparameter_ml300.h , I have changed the #define XPAR_OPB_INTC_0_SYSACE_COMPACTFLASH_SYSACE_IRQ_INTR 4 Also, in "xsysace_init", if I have xsa_device.gd = alloc_disk(16); , then the kernel hangs. So I have assigned alloc_disk(1), in which case the kernel boots-up fine. But when I issue 'fdisk / mount ', it goes through - ' XSysAce_SectorRead' which is being called from "xsysace_do_request". And at the nd of the function it hangs. I couldn't trace exactly where it hangs. Could you please suggest some pointers to debug on this issue? This is very critical for us and I am held up with this issue for the last 1 week. Thanks so much for all your help.
