Teardown

[helg]

I have opened the mola N3 housing, searching for the serial port UART0/ttyAMA0 pads for u-boot and Linux debugging.
There is a screw covered by the DDPAI sticker on the back side, that needs to be removed first.
DDPAI tried very hard to make the device unserviceable

Why do you need to do that?

Why do you need to do that?

I am planning to replace the Linux kernel with my own compiled version and need a recovery method if something goes wrong.
If it will be successful (and it will) i will do the same on my mini5.

That’s too deep for me to understand. I hope all goes well to your plan [emoji106]

I have decided to use mini5 for the experiments, because it is much easier to get to the UART0 pins, and it was a wise decision. I have flashed the fresh uImage and mini5 boots,
but 'main_app' does not find the shared library libDDPrompt.so. It looks like a simple LD_LIBRARY_PATH problem, although the 'native' DDPai uImage does not have this problem
Need to solder the pads for debugging
