Re: [Prex-devel] BeaglePort with MMU and CACHE

[Yocto <yoc...@gm...>]

Hi

> Please share your experiments with this patch!

In order to build on CYGWIN, you need the following changes
to LIBGCC_PATH and PLATFORM_LIBS in mk/gcc.mk:

   LIBGCC_PATH :=  $(shell $(CC) $(CFLAGS) -print-file-name=)

   PLATFORM_LIBS+= -L"$(LIBGCC_PATH)" -lgcc


With these, your patch build Prex 0.9.0 and generate a 249670 bytes prexos.

$ openssl dgst -md5 prexos
MD5(prexos)= 2af3784c6d3bca3989d9be37d2d428c7

But it hang after starting.  [ CodeSourcery G++ lite 2007q3-53 ]

ps: I miss stuff like "--build=builddir/beagle" from Prex 0.8 that kept the 
dir clean...
     Do you have any news for the release of Prex 1.0 ?

Thanks
// Yocto
