SK-AM62: Compile debian system, update image source Connection timed out

Hi Andi,

my build just completed and didn't have any issues. I followed the instructions at https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_02_01_Debian/exports/docs/debian/Building_Debian_Image.html but I made a change to check out the commit needed for SDK v9.2 by creating a new branch as follows:

a0797059@dasso:~/git/ti-bdebstrap (master)
$ git checkout -b 09.02.01.010 3d6148c0aafae30a8897bb326d461ca391c4472c
Switched to a new branch '09.02.01.010'

Then, I was able to do the build as follows:

a0797059@dasso:~/git/ti-bdebstrap (09.02.01.010)
$ sudo -E ./build.sh am62-bookworm-09.02.01.010
am62-bookworm-09.02.01.010
machine: am62xx-evm
bsp_version: 09.02.00.010
distro_variant: am62-bookworm

...and after that the build artifacts can be seen here:

Some things to double-check...

1. If you are behind a firewall/proxy, make sure the related ENV variables are accessible to the `sudo` user. In my case above variables like `https_proxy` are defined for the current user. And I use `sudo -E` to pass those along to the root user, so that the build process can download the needed files from the Internet
   
   
2. Try building on a different machine / a machine that's directly connected to the Internet (w/o proxy server)
   
   
3. Sometimes download issues can be transient due to temporary network issues. Re-starting the build sometimes allows it to move along further.
