Thanks for providing a fix. I have verified it by applying your change on top of the version https://github.com/pfalcon/esp-open-sdk checks out.

A way to fix this issue is this pull request: https://github.com/jcmvbkbc/crosstool-NG/pull/53 This also fixes https://github.com/pfalcon/esp-open-sdk/issues/307 It boils down to update the URL template in crosstool-NG/scripts/build/companion_libs/210-expat.sh from `http://downloads.sourceforge.net/project/expat/expat/${CT_EXPAT_VERSION}` to `https://github.com/libexpat/libexpat/releases/download/R_${CT_EXPAT_VERSION//[.]/_}`
