I have downloaded the yocto source code and also replaced curl, but i don’t know how to rebuild the yocto image?

  1. sudo apt-get install bison build-essential chrpath cifs-utils cmake coreutils curl desktop-file-utils diffstat docbook-utils doxygen fakeroot flex g++ gawk gcc git-core gitk graphviz help2man libgmp3-dev libmpfr-dev libreadline6-dev libsdl-dev libtool libxml2-dev libxml-libxml-perl make m4 ninja-build python-pip python-jinja2 python-pysqlite2 quilt samba scons sed subversion texi2html texinfo unzip wget texinfo chrpath

  2. sudo apt-get remove ccache

  3. sudo dpkg-reconfigure dash
    Answer “No” to the question.

  4. go into the yocto folder and type “make”.

  5. after compilation, the image will be build_bin/tmp/deploy/images/swi-mdm9x28-wp/yocto_wp76xx.4k.cwe

it shows sudo and make command not found

Did you install all the tools on your ubuntu pc?

yes,I think there is no problem in pc side
if i do the ssh connection,root@swi-mdm9x28-wp:~# mangoh@mangoh-vm:~$ ssh root@ and sudo commands are not found

curl version in mangOH as shown in below file

In the version i don’t know how to enable the SMTPS and SSl protocols? can you please help me to do this?

Of course the make command is type in pc side instead of module.!!!

Maybe you can use my image which is based on R13.3.

can i use this to wp7608

I think so, but you need to upgrade the FW to R13.3.

present firmware version are using in the board,as show in below

Im trying to send mail by using curl commands

curl --url ‘smtps://’ --ssl-reqd --mail-from ‘’ --mail-rcpt ‘’ --upload-file mail.txt --user ‘’ --insecure

but Im getting error like curl: (67) Login denied.please tell me how to solve this problem

I am not curl expert, also this is out of the mangoh topic.
Please double check on Ubuntu Linux PC first.

seems same problem on this one:

I don’t see problem with the following steps:

  1. Go to
  2. Go to “Less secure app access” section
  3. Turn on the access
  4. save the following to /tmp/mail.txt

From: “User Name”
To: “John Smith”
Subject: This is a test
