As you can see, your U-Boot version does not recreate the BBT
automatically as I told you it should. Please try rebooting the board
after scrubbing and then check U-Boot creates the BBT from U-Boot
command line.

I insist on the fact that this is something I could have spotted earlier
if you had blindlessly copy/pasted the *entire* trace, I don't
mind if it is big, it can be really interesting for others to get the
full trace.

This time I only need the trace without the "on-flash-bbt" property.

Thank you,
