SD card libblock bdpart linker problem

Tue Apr 29 00:50:50 UTC 2014

Do you have the right configuration options defined?

I rebuilt the raspberry Pi BSP with all tests ( --enable-tests=yes ). This
includes the testsuites/fstests/fsbdpart01 test.
The test links and runs, but I'm not sure if it passes ( or if it should
completely, since there is no IDE hardware on the Pi)
I get this output:
*** BEGIN OF TEST FSBDPART 1 ***
../../../../../../../rtems-git/c/src/../../testsuites/fstests/fsbdpart01/init.c:
143 (sc) == RTEMS_SUCCESSFUL

After this it seems to hang.

But , the init.c for that test may help you with the configuration in your
code.
