See > the patch agains sys/arm here: http://www.tomjudge.com/tmp/em-7210-patch >=20 Hi, Tom! It's great to hear you're working on this project! It's hard to say what's wrong with your setup, but here're some things I noteced. First, KERNVIRTADDR appears to be incorrect in your setup as you're trying = to map the kernel very low (0x01008000). In this case very low amount of virtual address space will be left for user-level applications. Try to map it to some address above 0xc0000000, e.g. to 0xc1008000. I also do not quite understand why you're using address 0xa0100000 for the first helper page mapping? What is the layout of memory on your board? Is anything useable is mapped here? Good luck! --=20 Stanislav Sedov ST4096-RIPE --Signature=_Fri__25_Sep_2009_17_34_00_+0400__U0UczWXkXcK3Y1.
