u-boot's Issues

Load MAC addresses from ART

Dual-boot default config cmdline config

u-boot environment stored from factory

To support dual-booting it is convenient to have the u-boot environment saved to the "env" partition from factory. One way is to start the serial console and type saveenv but this is cumbersome and error prone. Another way is to do an automatic saveenv if it is detected that it is not stored, like for example checking the CRC or if a variable is not there.

How to compile ram version ，u-boot

Very good !
Your version is very easy to compile.
But I want to compile a RAM version of u-boot. How to do it
Thank you.

Use redundant environment

To support power loss when updating the environment a redundant environment should be used.
u-boot has the config CFG_REDUNDAND_ENVIRONMENT for this:

	- CFG_ENV_ADDR_REDUND
	  CFG_ENV_SIZE_REDUND

	   These settings describe a second storage area used to hold
	   a redundand copy of the environment data, so that there is
	   a valid backup copy in case there is a power failure during
	   a "saveenv" operation.

It must be tested and an upgrade path from the current layout provided (probably using the previous sector to the ART)

Rescue script (load firmware while booting with a btn pressed)

Provide a way to load a new firmware using a rescue script that is trigered when booting while pressing the button. Ideally it is an http server like in https://github.com/pepe2k/u-boot_mod but a simpler tftp command could be used.
Another idea is to enable netconsole when the btn is pressed.
