Hi Jagadish

Thank you for your reply. I find it hard to download the bootloader for CAN. It opens to a github that doesn't seem to have a download function. Can you help?

Thank you

Hi Jagadish

As I was looking at bl_main.c, I saw this address apiLoadStart which doesn't seem to be defined. Can you explain? Thank you

You can't download, you have to clone it.

To clone it, first download following two applications:

Git - Downloading Package (git-scm.com)

Download – TortoiseGit – Windows Shell Interface to Git

Once you install these two then you can clone them like below.

1. Just right click and click on the 

2. Now give the URL and directory where you want to clone it.

URL:
https://git.ti.com/git/hercules_examples/hercules_examples.git

3. Now click on "OK" button to start the clone process.

After clone process completed you can see the demos at destination directory.

It is defined, it is extern from the bl_link.cmd.

So please clone the entire project and then do the build to avoid build errors.

Dear Jagadish

I have tortoise git installed on my PC and using it regularly but haven't used clone before. When I followed your instruction, I got error.

There is nothing in this folder that I am cloning to. 

For the bootloader uart, I have downloaded the zip file and am able to compile without errors. I have seen that apiLoadStart is declared extern.  But still an unknown value. It seems like you are trying to copy some binary content into that location. But what is that content and where is this location
