I do not think so, but you are the best to answer this question: unzip the file and check inside. However, even if it contains a u-boot.bin or whatever is your u-boot file, you have to extract it to write the bootloader at the right address. In most cases, you will see a separate image for u-boot in tmp/deploy/images diurectory. > > So, for modifying u-boot to adujst serial boaudrate, No. To modify the serial console under linux. > I understand that I can > add SERIAL_CONSOLE = "115200 ttyS0" to my local.conf according to your reply See Robert reply.

Usually you have a separate file for u-boot. Of course, if u-boot is part of the filesystem, you cannot use for a first installation because u-boot must be copied at a specific address.
