How is the ROM code loaded/provided on the BeagleBone Black?
I see a few possibilities:
It is loaded on in TI's factory and is immutable [unlikely]
It is flashed on during manufacture of BeagleBone [most likely]
Some other way
If it is open-source, where can it be obtained from?
If it is not open-source, and it is not flashed onto the Sitara by TI, can it be obtained as a binary blob, or can it be extracted from another Sitara?
How would it be flashed (via USB? JTAG?)
Does this ROM code take a similar function as a PC BIOS? Resetting initial system state (including configuring boot devices), then loading a bootloader?
This question is the sequel to this one.
I have been playing with FreeRTOS on some Cortex M3 and F1 boards for a while and I decided to start learning how more complex embedded systems work.
