Subject: Re: [gta02] u-boot boot menu regression ?
Ah, just got an update. Miles, I hope it's okay if I post this on
the list:
hello, can you help me change to the behavior of starting boot menu
like
before. We must stop automatically in boot menu. Now behavior of the
newest u-boot is not suitable for factory.
u-boot only stops automatically in the boot menu if booting from NOR.
Is this what you're looking for ? For NOR, the sequence is as follows:
- Hold and press AUX
- Hold and press POWER
- Continue holding AUX and POWER until the boot menu comes up
- Release AUX and POWER in any order
There was never a mode in which it always stopped in the boot menu
when booting from NAND (or JTAG, etc.), so I'm a bit confused what
you refer to with "before" ;-)
I need to change to stop automatically in boot menu.
If you really want to enter the boot menu unconditionally, even if
booting from NAND or JTAG, you can change board/neo1973/gta02/gta02.c,
around line 434, where it says
enter_bootmenu = menu_vote > 0 || booted_from_nor;
to
enter_bootmenu = 1;
However, if you do this, you have to replace u-boot with a version
that doesn't have this change before the device leaves the factory.
Does this help ?
Cheers, Werner
