Hi, I have the isp116x running fine on my ixp425 platform under kernel 2.4.27-uc1, where it maps to IXP425_EXP_BUS_CS4_BASE_VIRT = 0xf4000000 (the 2.4.27 driver does not perform ioremap). However with kernel - 2.6.12, (same platform and settings as in the 2.4.27 case) I provide the physical address IXP425_EXP_BUS_CS4_BASE_PHYS = 0x54000000 which is then ioremap'd (togther with 0x54000002 for addr) after which I am unable to read/write from/to the chip (all registers when read come with the same value of 0x1000)? Is it a mem mapping problem or is it maybe an issue with the read/write procedures (or maybe something else that I hvent thought about)?
Using: uClinux kernel - 2.6.12-uc0 ixp425 (with MMU on) isp116x-2.6.12.patch.bz2 --Danny _______________________________________________ linux-usb-devel@lists.sourceforge.net To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
