Solved! Go to Solution.
Look at the Section 3.4.3.2 of the e6500 Core Reference Manual:
https://www.nxp.com/docs/en/reference-manual/E6500RM.pdf
See also the Chapter 5.6.1.2.1 of the EREF:
https://www.nxp.com/webapp/Download?colCode=EREF_RM&location=null
See also u-boot readme file:
https://git.denx.de/?p=u-boot.git;a=blob_plain;f=README;hb=HEAD
Find the " "Hello World" Demo:" in this file. This example contains printing from u-boot.
Have a great day,
Pavel Chubakov

Hi Pavel,
Thank you for your reply.
But, I am working on the fresh board. We flashed u-boot alone with hard-coded RCW and we start u-boot debugging.
