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 as if the ACK was not sent by the BootROM.
Stefan, could you apply the patch below, recompile and then send the output again?
Sure. This is on top of next with the 39 patches:
