Hello meera,

I tried the first 2 lessons step by step just a week ago and it worked for me. Please, have a look at this document:

https://docs.google.com/document/d/10sk3_53w2TzufTk_FqixGmF2fpzLPV-yhQ0kjFXXQXg/edit?usp=sharing

I ran into a similar issue as you describe at the beginning of lesson 2. Right away, I tried the very same fix that worked in the first lesson, however it did not work for lesson 2 for the first time.

I rebooted the virtual machine and I tried to fix the Python version issue with the very same command lines from the earlier again:

export GIT_SSL_NO_VERIFY=1
cd ~
mkdir ~/bin
git clone https://gerrit.googlesource.com/git-repo
cd git-repo
git checkout 27da4ddeb9159573e0207f71e4d9b3ae286b5275
cp repo ../bin
chmod a+x ~/bin/repo
PATH=${PATH}:~/bin

Re-entering the repo command lines:

cd
mkdir fsl-community-bsp
cd fsl-community-bsp
PATH=${PATH}:~/bin
repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b jethro

It worked! Please try to reboot your virtual machine, follow the instructions again and let me know if it works for you as well.

Thank you

If you have look at L2: 00:03:24 section in the previously attached document, you will find the notes about this topic and also about some other issues you may run into:

When trying to download the files with command:

repo sync

I got the very same error as you do:

Fetching projects: 87% (7/8) pokyfatal: unable to connect to github.com:
github.com[0: 140.82.121.4]: errno=Connection timed out

fatal: unable to connect to github.com:
github.com[0: 140.82.121.4]: errno=Connection timed out

error: Cannot fetch meta-openrex from git://github.com/FEDEVEL/meta-openrex
Fetching projects: 100% (8/8), done.
error: Cannot checkout meta-openrex: ManifestInvalidRevisionError: revision jethro in meta-openrex not found
error: in `sync`: revision jethro in meta-openrex not found

The problem was the git port is restricted (https://github.com/npm/npm/issues/6285). Fixed this with following command:

git config --global url.https://github.com/.insteadOf git://github.com/

The second attempt of downloading (rest of the) files with:

repo sync

It worked out:

fedevel@fedevel-VirtualBox:~/fsl-community-bsp$ repo sync

... A new repo command ( 1.27) is available.
... You should upgrade soon:

cp /home/fedevel/fsl-community-bsp/.repo/repo/repo /home/fedevel/bin/repo

today I have been trying the above fix for repo-sync. I directly followed the steps given in "L1-L2 process double checked" page. It still doesnt work, the same "pokyfatal" error I got. Th solution, I found by in net and it is the following. In the openrex-> how to start with software page, in
cat > .repo/local_manifests/imx6openrex.xml << EOF

<?xml version="1.0" encoding="UTF-8"?>

<manifest>

<remote fetch="git://github.com/FEDEVEL" name="fedevel"/>

<project remote="fedevel" revision="jethro" name="meta-openrex" path="sources/meta-openrex">

<copyfile src="openrex-setup.sh" dest="openrex-setup.sh"/>

</project>

</manifest>

EOF

instead of using <remote fetch="git://github.com/FEDEVEL" name="fedevel"/>, use <remote fetch="https://github.com/FEDEVEL" name="fedevel"/>,
after that it worked. PFA snapsots (the solvedpoky snapshot).

OK. I have just seen your post, after I posted. I was looking at the https://docs.google.com/document/d/1...kjFXXQXg/edit#. Thank you

[meera]

This is a query in Lesson 2, at around 4.48 minutes. When you say " your board needs to be similar to the reference board", what it means? I have a situation, where I have two reference boards (board1 & board2), both having cortex-a9 core based processor from 2 different manufacturers. the third board is the board on which I need to port uboot, it has processor from the second board and other hardware from the first board. how should i proceed with developing uboot for the third board. Thanks

[meera]

continuing towards bit command. pfa snapshots, bitbake failed. I am trying for solution from my end too.
