Hello,
thank you for your answer, Steve. Unfortunatly your version from liHIL don't
work, too. There is the same error.
If I make a "strace gdbproxy msp430" (libHIL in 32bit version) I get the
following output:
...
open("/dev/parport0", O_RDWR) = 3
ioctl(3, PPCLAIM, 0xffffcf28) = 0
ioctl(3, PPDATADIR, 0xffffce34) = -1 EINVAL (Invalid argument)
dup(2) = 4
fcntl64(4, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE)
brk(0) = 0x8103000
brk(0x8124000) = 0x8124000
fstat64(0x4, 0xffffcc6c) = 0
...On a 32bit computer the syscall "ioctl(3, PPDATADIR, 0xffffce34)" works, the result is 0 and not -1. And if I use a short test-program with libHIL, both in 64bit mode, it works too. Therefore I think the problem is the syscall. Now, I don't know how to isolate the problem. I thought that the problem was the conversion of the pointer in the ioctl-syscall to unsigned long. Has anybody an idea? Steve, can you tell me please which library you use with gdbproxy? My ldd-output is linux-gate.so.1 => (0xffffe000) libHIL.so => /usr/local/msp430//lib32/libHIL.so (0x5556d000) libc.so.6 => /lib32/libc.so.6 (0x55591000) /lib/ld-linux.so.2 (0x55555000) These are all 32bit libraries.
