Good Morning! (to whome it may concern)
Anyway, I try to integrate openocd (svn:1248) into buildroot (svn:24436)
with uClibc-0.9.30 for an at91sam9263 box. strace outputs this and
finally hangs:
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbee45080) = -1 ENOTTY
(Inappropriate ioctl for device)
brk(0xe7000) = 0xe7000
close(3) = 0
open("jtagA9263.cfg", O_RDONLY) = 3
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbee45774) = -1 ENOTTY
(Inappropriate ioctl for device)
brk(0xe8000) = 0xe8000
read(3, "#################################"..., 1024) = 1024
read(3, "t_delay 20\njtag_ntrst_delay 20\n\n\n"..., 1024) = 1024
read(3, "\tmww 0xFFFFFC28 0x2018BF02 # CK"..., 1024) = 1024
read(3, "size> \n## <chip_width"..., 1024) = 251
read(3, ""..., 773) = 0
close(3) = 0
brk(0xe9000) = 0xe9000
brk(0xea000) = 0xea000
brk(0xeb000) = 0xeb000

gettimeofday({369, 740553}, NULL) = 0
gettimeofday({369, 741850}, NULL) = 0
brk(0xf1000) = 0xf1000
brk(0xf2000) = 0xf2000
brk(0xf3000) = 0xf3000
brk(0xf4000) = 0xf4000
gettimeofday({369, 764755}, NULL) = 0

gettimeofday({369, 803867}, NULL) = 0
open("/dev/mem", O_RDWR|O_SYNC) = 3
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, 3, 0xfffff) = 0x40005000
mmap2(NULL, 1052672, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, 0,
0) = 0x400ba000
A look through the code showed that the failing ioctl calls belong to an
fopen call that opens and reads a given file. Why does that fail? Is
there a known solution to the problem or is it of topic and uClibc news
is the right place?
