Summary0002443: Serial overflow results in off-by-one error on serial line
DescriptionWhen U-Boot starts and gets more than 8 characters on the serial line as input before the command line is active, the serial communication has a displacement of one. This means that when a character is typed on the command line, the previous character is echoed instead.
Steps To ReproduceWhen U-Boot starts, there is a small delay after the NAND memory size is output and before the MMC is detected.

Test 1:
Type a single character in this pause. Everything is OK, command line input is correct.

Test 2:
Press a key until it repeats. Now start the board. This results in sending more than 8 characters to the board in this pause above. Now the input on the command line is off by one.
