loading u-Boot in memory instead of flashing it

Question

In my ARM based custom board, I flash u-boot to NAND whenever I do changes on that. (putting some debug statements/modification). Is there any way to directly load the uboot ima

Answer 1

Just take in mind (be care of) the hardware that you are configuring in your modified U-Boot. U Boot is intended to initialize critical modules, some of them are not able to be re-configured on the fly or they may not performe as if they were initialized/configured at startup.
