Attached is patch that fixes segfault problem but is not helpful in creating environment and mounting filesystem. diff --git a/arch/sandbox/board/hostfile.c b/arch/sandbox/board/hostfile.c index 38a52a8..52212f7 100644 --- a/arch/sandbox/board/hostfile.c +++ b/arch/sandbox/board/hostfile.c @@ -107,7 +107,8 @@ int barebox_register_filedev(struct hf_platform_data *hf) dev->platform_data = hf; - strcpy(dev->name, "hostfile"); + /* Registering 2 devices with same name creates problem? */ + strcpy(dev->name, hf->filename); dev->size = hf->size; dev->map_base = hf->map_base; Strace log for problem ================= execve("./barebox", ["./barebox", "-e", "env.bin", "-i", "cramfs.bin"], [/* 22 vars */]) = 0 brk(0) = 0x216d1000 access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) mmap2(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xa3f000 access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) open("/etc/ld.so.cache", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=61576, ...}) = 0 mmap2(NULL, 61576, PROT_READ, MAP_PRIVATE, 3, 0) = 0x141000 close(3) = 0 access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) open("/lib/tls/i686/cmov/librt.so.1", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\300\30\0\0004\0\0\0"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0644, st_size=30684, ...}) = 0 mmap2(NULL, 33364, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0xe49000 mmap2(0xe50000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x6) = 0xe50000 close(3) = 0 access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) open("/lib/tls/i686/cmov/libpthread.so.0", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0 J\0\0004\0\0\0"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=117086, ...}) = 0 mmap2(NULL, 98792, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x4cb000 mmap2(0x4e0000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x14) = 0x4e0000 mmap2(0x4e2000, 4584, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x4e2000 close(3) = 0 access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) open("/lib/tls/i686/cmov/libc.so.6", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0000m\1\0004\0\0\0"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=1405508, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xbad000 mmap2(NULL, 1415592, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x28e000 mprotect(0x3e1000, 4096, PROT_NONE) = 0 mmap2(0x3e2000, 12288, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x153) = 0x3e2000 mmap2(0x3e5000, 10664, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x3e5000 close(3) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xbda000 set_thread_area({entry_number:-1 -> 6, base_addr:0xbda6c0, limit:1048575, seg_32bit:1, contents:0, read_exec_only:0, limit_in_pages:1, seg_not_present:0, useable:1}) = 0 mprotect(0x3e2000, 8192, PROT_READ) = 0 mprotect(0x4e0000, 4096, PROT_READ) = 0 mprotect(0xe50000, 4096, PROT_READ) = 0 mprotect(0x28c000, 4096, PROT_READ) = 0 munmap(0x141000, 61576) = 0 set_tid_address(0xbda728) = 9951 set_robust_list(0xbda730, 0xc) = 0 futex(0xbf9bb9c0, FUTEX_WAKE_PRIVATE, 1) = 0 futex(0xbf9bb9c0, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 1, NULL, bf9bb9d0) = -1 EAGAIN (Resource temporarily unavailable) rt_sigaction(SIGRTMIN, {0x4cf410, [], SA_SIGINFO}, NULL, 8) = 0 rt_sigaction(SIGRT_1, {0x4cf8f0, [], SA_RESTART|SA_SIGINFO}, NULL, 8) = 0 rt_sigprocmask(SIG_UNBLOCK, [RTMIN RT_1], NULL, 8) = 0 getrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM_INFINITY}) = 0 uname({sys="Linux", node="mjain-laptop", ...}) = 0 mmap2(NULL, 8392704, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xe52000 brk(0) = 0x216d1000 brk(0x216f2000) = 0x216f2000 fstat64(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 0), ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xa0c000 write(1, "add file env.bin()\n", 19add file env.bin() ) = 19 open("env.bin", O_RDWR) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=65536, ...}) = 0 mmap2(NULL, 65536, PROT_READ|PROT_WRITE, MAP_SHARED, 3, 0) = 0x110000 write(1, "add file cramfs.bin()\n", 22add file cramfs.bin() ) = 22 open("cramfs.bin", O_RDWR) = 4 fstat64(4, {st_mode=S_IFREG|0644, st_size=4096, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, 4, 0) = 0x120000 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Segmentation fault I would appreciate any kind help offered.
