Hi,
I have my custom board successfully booting using my bootcmd environment variable.
I would like to have alternate boots from user keys (derived from an I2C device if that's relevant) but if I set a key1 environment variable it is not executed in place of the saved bootcmd. The user guide says it should be (section 5.4.2 "User keys") but I have had zero success; I have searched every single file in the repo for "key1" and nothing helps (only reference is an env_set key1="on" - or "off" - for one board).
What black magic is needed to get the alternate boot(s) to work , please?
Tim.
