Hi Fabio, Thank you for your help.
1. You are right. It is not an U-boot mainline configuration. I am porting U-boot to our company's hardware platform https://www.supermicro.com/manuals/other/CSE-PTJBOD-CB3.pdf with SoC AST2400 from Aspeed embedded with an ARM core ARM926EJ 32-bit RISC CPU. 2. You are right. I have not exported the tool chain. Could you please share me a link to a readme in setting up the tool chain for Ubuntu cross build environment ?
