Hi I am using beagle bone black and writing i2c driver just for learning. I used am335x TRM and i2c1 at address 0x4802a000 as mentioned in TRM.
I did the following : void * addr = ioremap(phy_addr, length); unsigned x = readl(addr); Where phy_addr is the physical address (0x4802a000) mentioned in TRM. And length is the end address - start address (0x4802afff - 0x4802a000) Now on 'read' it crashes and gives me the following error when checked in dmesg : Unhandled fault: external abort on non-linefetch. Need help on this. Thanks:) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
