Andrii,

I have attempted to update the bootloader from the srec files created by
the bitbake command.

I believe I have been able to update it, but I am still obtaining the same
results. The serial output is shown below:

I have noticed that the uboot date has not changed from 2015.04 although
the build date is from the last time I ran a bitbake command.

I do not know what version of uboot should be used without breaking the
current compiling versions.

Are there any other modifications that I can attempt?

Thank you very much for your time and patience.

Best regards,

Jairo
