Geert: I disabled the I82559ER interrupt but the problem remains the same.
I suspect that my problem is due to the memory map that I'm using. I configured the MCU such that DRAM starts at zero so that I get access to the vector table. Because I could not flash the board with the FRU utility. I'm not enabling the Direct address translation and I'm setting the SOMWVR to 0x88000000. The base address of I82559 is 0x88100000. Note that the DRAM size is 2x32 Mb. Flash0 is mapped to 0xa0000000 Flash1 is mapped to 0xFE800000 The SATU is not responding to any read/write initiated by an internal bus cycles. The SATUR got set 0x2000 (master abort bit). The SATISR has a value of 0x00000008 (master abort). If you have an IQ80310 were you able to flash successfully with FRU? Thanks for your feedback. >From: Geert Stappers <[EMAIL PROTECTED]> >To: "Mohamoud musse" <[EMAIL PROTECTED]> >CC: [EMAIL PROTECTED] >Subject: Re: IQ80310: Accessing I82559ER registers via PCI >Date: Sun, 18 Nov 2001 21:27:03 +0100 > >At 20:45 +0100 11/18/01, Mohamoud musse wrote: > >Hello: > > > >I'm getting a master abort everytime I try to access the I82559ER >registers. > >I can access the config space of the ethernet device without problems. >Could it be that the master abort is triggered by IRQ of the I82559? > > > > >Any ideas would be appreciated. >Disable Interrupt ReQuest from that chip. > >Geert > > _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm Please visit the above address for information on this list.
