Configuration
You can control the "default boot" behavior (ie, what happens when you don’t hold down any keys). If you are a developer that does not want to constantly clear the bootcnt, you can also cause CyanoBoot to clear the bootcount automatically at every boot. To do this, three configuration files may be added to /bootdata (partition 6) on the emmc.
CONFIG #1: BOOT DEVICE
This will cause CyanoBoot to always boot from the emmc boot partition rather than SD. In this way, you can boot “through” a bootable SD card to whatever is on the emmc.
To Make Default Always Boot To EMMC
$ echo -n “1” > /bootdata/u-boot.device
CONFIG #2: ALTBOOT
Aside from the normal boot and recovery boot, a third boot option is available, called “altboot” (alternate boot). This is a kernel/ramdisk pair that can be used for a third firmware, an overclocked kernel, or whatever you like. If you choose the “altboot” as a default and it does not exist, your boot will fail.
As discussed above, the altboot.img file goes in the following location:
SDCard: file on p1 called “altboot.img” (no special padding or offset)
EMMC: file at /bootdata/altboot.img (no special padding or offset)
To Make Default Always Boot to “altboot”
echo -n “1” > /bootdata/u-boot.altboot
CONFIG #3: CLEAR BOOTCOUNT -- You can automatically zero out the bootcount with every boot. To set this:
To Make Default Automatically Clear BootCount
echo -n “1” > /bootdata/u-boot.clearbc
NOTE: A version of “Nook Tablet Tweaks” is planned to automate the above options much as Nook Color Tweaks does for the encore device in CM7.
Do you mind if I add these settings to "NT Hidden Settings"?
