The generic image will find and update file and automatically start CM7 installation. That’s all, now unmount the SD card, insert it on the Nook and power off. $ mount /dev/sdX1 /media/boot $ cp cm_encore_full-153 /media/boot There should be only one partition on the SD. One the file has been downloaded, copy it to the SD card. Download a nightly build of CM7 for the Nook from I’m using -153 but I guess that a newer or older should work either. To know which block device is associated with your SD card, insert your card and look the kernel log messages with dmesg for example.Īfter done with writing eject and insert again your SD card on your computer.

Where X is the block device name for your SD card. Then insert your SD card and copy the image to your SD card: $ dd if=generic-sdcard-v1.3.img of=/dev/sdX bs=1024

$ wget $ gunzip generic-sdcard-v1.3.img.gz To install a CM7 on your SD card first download and gunzip the generic sd card image. I prefer to only install stable software on my nand so I did an CM7 installation on an SD card and used that for development. So these are the steps to build a custom Android kernel for your Nook Color:ġ- Installing CyangenMod (CM7) on an SD card:įirst you have to decide if you want to install your kernel on your boot partition of your nand memory or using an external SD card. This happens even more with my hobbyists projects since I don’t work with them on a daily basis. I context switch more than I would like and when I comeback to something I didn’t do in a few days, I have to remember what are the exact commands to build the uImage, what is the defconfig file I use to build each kernel, etc. Second, I wanted to document the process for myself. I want to document how to build your own Android kernel for two reasons. Since I don’t have a fully functional Linux kernel for the Nook Color, I’m developing against an Android kernel. So to work in a driver first you need to compile a Linux (or Android) kernel. On the last post I told that I’m working on Cypress TrueTouch(tm) touchscreen driver for mainline inclusion.
