Problem with building the omap3530_dvsdk_combos_3_16.Any help?

I follow instructions in omap3530_dvsdk_combos_release_note.html
configuring the environment for dvsdk 3530 combos 3.16.
And type in the command line:

davinci@davinci-laptop:/opt/TI/dvsdk_3_00_00_29/
omap3530_dvsdk_combos_3_16$ make
Makefile:56: Your BIOS needs to be patched for SDSCM00004525!
Makefile:56: *** Please copy /opt/TI /bios_5_32_04 /packages/ti/
rtdx/package_export.xdc to /bios_5_32_04。 停止(stop)

Questions:

1. my bios_install_dir =/opt/TI/bios_5_32_04, and the version meets
the requirement according to releasenote. where and how should I get
that patch, SDSCM00004525?

2. I don't find any file named package_export.xdc in copy /opt/TI /
bios_5_32_04 /packages/ti/rtdx/package_export.xdc? so why this error
happens?

3. If I want to make use of dvsdk, especially dvbt+servers+codecs in
my beagleboard, what scripts should i modify?

For your consideration:
