That's OK if they insist. But it is due diligence to at  least  point
out  the  potential  trouble  they  are  inviting. Which we have done
hereby.

But out of curiosity: please do me a favour and measure the time from
power-up to U-Boot prompt. Then "setenv baudrate 115200; saveenv" and
measure again.  Thanks in advance.

Best regards,

Wolfgang Denk
