Hello,

I’m new to u-boot. Has anybody tried to make 2-step u-boot? I mean a really small u-boot (the first u-boot) possible only needs to initialize the CPU, memory… and load the full featured (the second u-boot) u-boot and the Linux to the RAM. In this way the second u-boot as an application can be updated on the fly.

Could you please share your knowledge here If you have done the job or the similar?

Regards,
