Thomas,

Problem solved.  The DOWNLOAD_SCP requires two arguments, full path with
filename and filename.

Reading package/pkg-download.mk shows

DOWNLOAD $(FOO_SITE),$(FOO_SOURCE)

but scp seems to need

DOWNLOAD $(FOO_SITE)/$(FOO_SOURCE), $(FOO_SOURCE)

[...]

This is a summary of the ti-tools.mk.

XDC_VERSION=3_16_01_27
XDC_SITE=scp://host:/home/steve/TI_Tools
XDC_SOURCE=xdctools_setuplinux_$(XDC_VERSION).bin

$(DL_DIR)/$(XDC_SOURCE) :
        $(call DOWNLOAD_SCP,$(XDC_SITE)/$(XDC_SOURCE))

Note that you should call DOWNLOAD instead of DOWNLOAD_SCP directly.
This will make sure to respect the primary site and other mechanisms
that are in place.

Best regards,
Thomas

I'm putting together a TI toolchain package but as some of the required
packages are export controlled I need to host them on my institutional
machine to control access. I think scp is the best choice for this but
the
scp scheme does not prompt for passwords and users who haven't setup
public-key ssh access are unable to download the packages. Why does the
DOWNLOAD_SCP scheme not prompt the user for a password?

In my test, using scp as primary site, it does ask for a password if
one is required.
How have you configured the package? Have you specified a user?

This is a summary of the ti-tools.mk.

XDC_VERSION=3_16_01_27
XDC_SITE=scp://host:/home/steve/TI_Tools
XDC_SOURCE=xdctools_setuplinux_$(XDC_VERSION).bin

$(DL_DIR)/$(XDC_SOURCE) :
        $(call DOWNLOAD_SCP,$(XDC_SITE)/$(XDC_SOURCE))

Have you tried running scp manually? Is a password requested there? Is
the same command used as Buildroot does?

Yes, I've manually run the scp command that is generated and it does prompt
for a password.

This is what buildroot generates.

make -C /home/steve/plat/overo/src/buildroot O=/home/steve/plat/overo/.
mkdir -p /home/steve/plat/overo/host/ti/tools
test -e /home/isteve/plat/overo/download/ || scp
'host:/home/steve/TI_Tools/xdctools_setuplinux_3_16_01_27.bin'
/home/isteve/plat/overo/download/

manually running scp
'host:/home/steve/TI_Tools/xdctools_setuplinux_3_16_01_27.bin'
/home/isteve/plat/overo/download/
prompts me for password.  I do not specify username as scp assumes the
username of the current user which is okay for my purposes.

Thanks.

Steve
