I checked by quickly starting a terminal app and it does not seem that the CPU did go through a reboot. Nothing on the UART at this stage.
BUT: The tests I did in this mail were done with your 39 patches applied on top of "master-kwboot" [1]. Here booting with 115k works as explained below.
Now I applied the same 39 patches on top of "next" [2]. And here not even booting with 115k works on my AXP target. It always hangs at this stage:
So default baudrate 115200 works fine on master+39patches and does not work on next+39patches? Could you check if it works on next without applying any patch?

This seems to work at least for 115k in the "master-kwboot" branch.
Any ideas?
Thanks, Stefan
