Could you clarify the following.
- If we want use u-boot in embedded system, The initial part of u-boot runs from the Flash.So Flash is mandatory.
My goal is :
On my embedded platform, the flash is not yet ready.So i wanted to load u-boot on DDRAM/SRAM by changing the TEXT address and set PC to start of start () using JTAG debugger.
could you please clarify Is it possible to boot from RAM as i mentioned above.
Any environment variables are access from the Flash during u-boot bootup time.
