This will increase the boot time by 2 seconds : why is that needed ?
Thanks for commenting. My intent is to give by default a reasonable time for the end-user to react and break the boot-sequence if needed (and avoid the nasty racing against the clock for this precious key-press).
My motivation for this is that I see RIoTboard/MarsBoard mostly as boards that people can use for experimentation/prototyping, and not as a finished end-product, thus my thinking that the slightly increased boot-time won't be a critical issue for such applications. Still everyone can change the delay at will if they want to optimize the boot.
Other hobby boards also have similarly handy boot-timings, like Wandboard (5s), Novena (5s), Udoo (3s).
OK seems reasonable.
I disagree. I think it's an unnecessary, unneeded, unreasonable tripling of the boot time.
I have 2 things to say about this: 1. In theory we can also question why the initial boot delay was selected to be 1s. 2. You imply that the "users" want ultra-fast boot times for riotboard. Being myself one of the riotboard users, I can assure you that such generalization is excessive.
Rather than leaving people to patch out this unwanted behaviour, I'd suggest promoting CONFIG_BOOTDELAY into a Kconfig option, leaving the default as-is.
This is a good idea in general, I don't mind it.
This also leads to a slightly less unreasonable increase in bootdelay to 2s from config_distro_defaults.h
Well, this is again subjective - we can always argue that 2s is both too long and too short for selected use cases, so I don't understand the qualification "less unreasonable".
In summary - I won't carry a war for this change, as it doesn't worth it. I just tried to contribute a tiny bit of improvement to the already excellent work of Eric, so we can have a silk-smooth out-of-the-box U-Boot user experience, and I'm doing this as an actual riotboard user. That's all.
Thanks for sharing your viewpoint.
Kind regards, Nikolay
