Hi,
I'm moving from 16.08 to 16.11. I had previously built and run my custom os and
apps successfully on releases since 14.xx. The kernel is base-hw and the
platform is based on TI's AM437x.
Using the same make script that I used in 16.08, the script successfully built
all the components on 16.11 without error. However, in the last stage, to build
the boot image, it first failed with the error "unknown platform no linker
address known". I traced this to a new tool module, tool/run/boot_dir/hw.
Apparently this script requires that each unique base-hw kernel platform have a
table entry that contains the name used for the platform plus an address which
I assume is the load address for the boot image. Is there a documentation
update describing this new feature in a bit more detail than the paragraph in
the release notes? Adding to the table the necessary entry and running the make
script again produced another error which has me stuck. The full make output is
attached but the error that is now occurring complains that modules have been
built for hardware floating point but the libgcc.a is not built to using the
vector floating point register arguments. The message output for one of the
libgcc.a modules is:
/opt/usr-local/genode-gcc/bin/../lib/gcc/arm-none-eabi/4.9.2/../../../../arm-none-eabi/bin/ld:
error: var/run/rico_fs.core uses VFP register arguments,
/opt/usr-local/genode-gcc/bin/../lib/gcc/arm-none-eabi/4.9.2/libgcc.a(_fixsfdi.o)
does not
Since release 15.02 I've been compiling some of the modules with floating point
hardware flagged on, so rico_fs.core does indeed have VFP register usage in it.
So why is this error showing up now and not in prior releases and how may I fix
it?
Thanks,
Bob Stewart
