Could you please help me in resolving the "arch/arm/lib/vectors.S:87: Error: no such instruction: `b reset' ?"

[Liu Wang]

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 ?

Sincerely,
Liu Wang

This is not a configuration supported by U-Boot mainline.

Have you exported the toolchain?
