We are building the following environments:

The $bash install-tools.sh command stops with the following error:

 == Install base command line tools
== Install additional tools
=== tar xvzf nuttx-tools.tar.gz -- strip-components=1-Cnuttx-tools install-tools.sh: 145 lines: cd:nuttx-tools/kconfig-frontends: No Such

'nuttx-tools/genromfs-0.5.2.tar.gz'
=== ./configure --prefix=/opt/spresenseenv/usr --disable-shared --disable-nconf  
=== make install

install-tools.sh appears to be due to a failed download with a file size of 0 for nuttx-tools.tar.gz below L.137.

download${NXTOOLURL}/get/master.tar.gz${NXTOOLARCHIVE}

Master.tar.gz could not be found in Nuttx tool below.
https://bitbucket.org/nuttx/tools/src/master/

I am guessing that the reason is probably because the file was organized on Nuttx site and the spresense was not able to handle it.
If you are editing install-tools.sh locally, what is master.tar.gz?
