I am unable to build an extensible SDK for my RISC-V machine.
Required Details:
Also, I am able to build the normal SDK successfully.
I ran this  for my custom machine "cdac-ooo".

MACHINE=cdac-ooo bitbake core-image-minimal -c populate_sdk_ext

ERROR: Task (/home/qc/anaadi/riscv-cdac-v1/build_cdac-ooo-core-image-minimal/tmp-glibc/work/cdac_ooo-oe-linux/core-image-minimal/1.0-r0/sdk-ext/image/tmp-renamed-sdk/layers/openembedded-core/meta/recipes-graphics/xorg-util/util-macros_1.19.2.bb:do_fetch) failed with exit code 'setscene whitelist'

I am attaching the log file with reference to the error.

I also tried using,
SDK_EXT_TYPE = "minimal"
SDK_INCLUDE_TOOLCHAIN = "1"
but that gave me an empty sysroots directory without the tool-chain.

Please Let me know what am I missing or how can I rectify this error.
