how to resolve page_fault

Hi list,
I tried to find out what happened to the booting of okl4 at gta02(Free Runner). The problem I met is no more respond after the msg "OKL4 - (provider: Open Kernel ..." is displayed. The build cmd I use is: ./tools/build.py machine=gta02 project=examples pyfreeze=false example=hello \ pistachio.TOOLCHAIN=gnu_arm_toolchain For more verbose debug msgs, I added CONFIG_VERBOSE_INIT and CONFIG_KDB_ON_STARTUP to machines.py, see the attached file. The other attached file okl4.log is the complete log, including booting and how I find out the problem through KDB. The reason why I got no respond is because of PAGE_FAULT when switching from idle thread to _hello_ thread. We could see the instruction address(pc) when page fault happened is _0x001056a0_ from okl4.log. 00105640 <hello-device_setup_impl>: ... 105690: e284400c add r4, r4, #12 ; 0xc 105694: daffffef ble 105658 <hello-device_setup_impl+0x18> 105698: e5952068 ldr r2, [r5, #104] 10569c: e59fe160 ldr lr, [pc, #352] ; 105804 <hello.text+0x5804> 1056a0: e5923000 ldr r3, [r2] According the asm code, r2 = memory(r5+#104) = memory(0x200d98+#104) = memory(0x200e00) = 0x0 r3 = memory(r2) = memory(0x0) When I dump the memory (0x0), it show ######## always, I thought that's why page_fault. I'll keep trying and any idea/hint how to resolve this problem is very appreciated. ;) Captured from okl4.log: > go DABT @ 00000000 [00000000], pc = 001056a0, tcb = f0103d20, fs = 5 --- KD# ARM_DATA_ABORT --- > frame == Stack frame: f0023f58 == cpsr = 200000d3, pc = f0010a78, sp = f0023f58, lr = f0010a78 r0 = f001a944, r1 = f9000000, r2 = 85, r3 = ffffffff, r4 = 0 r5 = 5, r6 = f00243d0, r7 = 200df8, r8 = f0103d70, r9 = 1075b4 r10 = f0103d20, r11 = 5, r12 = 0 > dumpframe tcb/tid/addr [current]: current == Stack frame: f0103d70 == cpsr = 20000010, pc = 1056a0, sp = 1108a8, lr = 10f79c r0 = 200d98, r1 = 0, r2 = 0, r3 = 105c2c, r4 = 10f83c r5 = 200d98, r6 = 8, r7 = 200df8, r8 = 0, r9 = 1075b4 r10 = ffffffff, r11 = 10f6b8, r12 = 200db0 > go PF @ 00000000 [00000000], pc = 001056a0, tcb = f0103d20, fs = 5 --- KD# ARM_PAGE_FAULT --- > go user read pagefault by f0103d20 at 00000000, ip=001056a0, ksp=f0023f80 --- KD# PAGEFAULT_USER --- > go DABT @ 00000000 [00000000], pc = 001056a0, tcb = f0103d20, fs = 5 --- KD# ARM_DATA_ABORT --- > go PF @ 00000000 [00000000], pc = 001056a0, tcb = f0103d20, fs = 5 --- KD# ARM_PAGE_FAULT --- > memdump Dump address [0x200000]: 0x200e00 00200e00 00000000 00000000 00000000 00000000 ........ ........ 00200e10 00000000 00000000 00000000 00000000 ........ ........ 00200e20 00000000 00000000 00000000 00000000 ........ ........ 00200e30 00000000 00000000 00000000 00000000 ........ ........ 00200e40 00000000 00000000 00000000 00000000 ........ ........ 00200e50 00000000 00000000 00000000 00000000 ........ ........ 00200e60 00000000 00000000 00000000 00000000 ........ ........ 00200e70 00000000 00000000 00000000 00000000 ........ ........ 00200e80 00000000 00000000 00000000 00000000 ........ ........ 00200e90 00000000 00000000 00000000 00000000 ........ ........ 00200ea0 00000000 00000000 00000000 00000000 ........ ........ 00200eb0 00000000 00000000 00000000 00000000 ........ ........ 00200ec0 00000000 00000000 00000000 00000000 ........ ........ 00200ed0 00000000 00000000 00000000 00000000 ........ ........ 00200ee0 00000000 00000000 00000000 00000000 ........ ........ 00200ef0 00000000 00000000 00000000 00000000 ........ ........

Hi Sean,
Good to see you're making progress with the port :-) On Tue, January 20, 2009 10:16 am, Sean Chiang wrote: <..> > The reason why I got no respond is because of PAGE_FAULT when switching > from idle thread to _hello_ thread. > > We could see the instruction address(pc) when page fault happened is > _0x001056a0_ > from okl4.log. > > 00105640 <hello-device_setup_impl>: > ... > 105690: e284400c add r4, r4, #12 ; 0xc > 105694: daffffef ble 105658 <hello-device_setup_impl+0x18> > 105698: e5952068 ldr r2, [r5, #104] > 10569c: e59fe160 ldr lr, [pc, #352] ; 105804 > <hello.text+0x5804> > 1056a0: e5923000 ldr r3, [r2] > > According the asm code, > > r2 = memory(r5+#104) = memory(0x200d98+#104) = memory(0x200e00) = 0x0 > r3 = memory(r2) = memory(0x0) > > When I dump the memory (0x0), it show ######## always, I thought that's > why page_fault.

In this case, it's most likely that you're hitting a null pointer exception (you obviously wouldn't want 0x0 mapped, since it's used to represent NULL). Some pointers for debugging this: I'd assume this is occurring in your serial driver (since that's the only driver that the hello example uses). libserial's serial_init function calls device_setup, which gets marshaled through to your s3c2442_uart's device_setup_impl function - this is where to start looking for the error. An input is likely bad - in particular, check the resources that are passed to device_setup_impl. You can see libserial hardcodes the memory resource to an elfweaver-provided environment variable called "MAIN_SERIAL_MEM0" - check that this exists (either in your machine.xml [you should see a physical segment called "serial_mem0", elfweaver just prepends it with the name of the first space, which is always "MAIN"] or by running an objdump -s on your system image, searching for cell_env, and checking the constants). Hope that gives you a place to start - let us know how you go.
