Flashing a new Debian image to the Beaglebone Black, it crashed due to a power outage.
After the incident, the Beaglebone does not boot (at boot time, the four LEDs stay lit), nor can be flashed.
Connecting to serial port, I can watch the boot logs and enter to U-Boot terminal.
The boot logs are:

And here we have the four user LEDs lit.
The main issue seems to be the lack of the initrd.img file. Although, some other kernel files could be missed too.
Avoiding the option of having a hardware issue, I need to restore the kernel or a whole Linux image.
- Can it be done through serial port (as a kernel update)?
- Which is the best way to restore the Beaglebone?
KR!
