I’ve followed to the letter the article which gets NVIDIA’s JetPack with L4T running on the TK1:
This was working perfectly, with Ubuntu running smoothly. Initially there were some configuration issues getting the LVDS display to work correctly however this was resolved and it all just worked.
I then followed the “Building Linux Kernel from Source” section of the article so I could add in support for the ADV7280, Wi-Fi, I2C devices, etc, etc and following compilation, deployed my new kernel (and L4T rootfs) to the target.
Unfortunately now, I’m stuck with a number of issues:
The “ubuntu” auto login no longer works and the debug console reports many “Authentication failure” messages before it no longer accepts any character input - I’m not able to try logging in as
root or any other account as the console won’t accept anything.
Likewise, if I look at the display, I’m presented with a “The system is running in a low-graphics mode” and a number of recovery options - all of which either do nothing or cause the system to eventually freeze.
Have any of the Toradex team experienced this kind of behaviour? All steps in the article were covered.
