Please see my pastebin output for strace
and ldd
on an ARM926 processor. The binaries inside libftd2xx1.1.12 have multiple processors. Ensure you are using release/build/arm926
. I can run the statictest
binary on an ARM926 CPU, with eglibc and Linux 2.6.36.
From the ldd
output, the following libraries are required.
libdl.so.2
- dynamic loading.
librt.so.1
- real-time library
libpthread.so.0
- pthreads
libgcc_s.so.1
- gcc helpers.
libc.so.6
- eglibc library
ld-linux.so.3
- the Linux shared library loader.
A functional ldd
is not needed and the following command should display libraries,
LD_TRACE_LOADED_OBJECTS=1 LD_WARN=yes LD_BIND_NOW=yes LD_VERBOSE=yes \
/lib/ld-linux.so.3 ./libftd2xx.so.1.1.12
Verify that the statictest
binary work. If so, try to set LD_LIBRARY_PATH
to the release/build/arm926/libftd2xx.so.1.1.12
location. From the strace
output, the paths /lib/tls/v5l
and /lib/tls
are preferred over /lib
. All of the libraries listed above should be in /lib
. You can try to ln
(hard link) them to that location. Also, from the strace
output, the /proc/bus/usb
filesystem should be mounted. This is a kernel config option. /sys/bus/usb/devices
is used extensively to find devices; it is unlikely that this is missing on your Ubuntu 12.04 ARM Linux. There is also a libd2xx_table.so
which is most likely used to find non-standard USB descriptors.
Finally, it would be helpful to be more descriptive of the problem. You try to run some program and there is no output? Or you run the program and it has an exception? If the statictest
ARM binary fails to run, then your original assumption might be correct. It is possible that the older 2.6.32 kernel (or ld-linux.so) finds ARM926EJ-S
compatible but your newer Ubuntu 12.04 does not find it compatible. In this case, use man ld-linux
on a PC host to see the ld-linux.so
environment variables. Specifically, LD_DEBUG
and LD_ASSUME_KERNEL
may be helpful to coax the loader to load the binaries.
