Hello - 

 

the docs for uboot scripting do not seem to be available at:

http://www.denx.de/twiki/bin/view/DULG/UBootScripts 

 

I want to set some uboot env variables and then run two uboot commands.  I know how to write the script, however I need to know what steps to take to make the script readable by uboot, and then how do I execute the script.

Also - off topic - how can I set a buffer in flash at a specified address to all zeros?  I want a certain buffer to be zeroed out when uboot is flashed - so the buffer (in this case would be in flash, and when relocated - also be in ram - I know how to declare a static, and to initialize a buffer, however I can't figure out how to locate that buffer at a specific address using either preprocessor commands, or linker script commands. oh - and I want to do this in c - not assembly.
