Finally Getting Somewhere with OE and U-Boot

After what seems like forever, trying to resolve a problem getting consistently working images and kernels, I've finally figured out the problem.

HOWTO: Using U-Boot

Well you finally have a working U-boot bootloader on your Mini2440 or Micro2440, well here are the instructions for actually flashing kernel images and root filesystems using it...

HOWTO: Compiling and Flashing U-Boot onto Mini2440

The bootloader that comes factory installed on the Micro2440 and the Mini2440 board is called Supervivi. I don't personally like it. It has very limited support and requires a YAFFS filesystem for the root filesystem. So when I bought my board I began to immediately search out an alternative. The bootloader by choice, it seems, is a modified version of U-Boot with modifications for the Mini2440 board's hardware

Welcome to my FriendlyARM Mini2440 - Micro2440 Blog

I recently purchased a Micro2440 development board with 7" display. One of the things I've noticed is the lack of information, real helpful information, regarding the device. It takes a lot of digging and sifting through stuff in order to get what you need. People have placed step by step instructions up, but most of those are geared for the Mini2440 with a 3.5" display and 64MB NAND. My goal with this site is to provide information that both board owners can use, but that is meant to help those who are buying the Micro2440.

Working with this board the past couple of weeks has been both a nightmare and a lot of fun. I've not delved this deep in to something in a long time. The weeks prior to receiving my device, I worked in Gentoo preparing myself with and familiarizing myself with the aspects of Embedded development. While I've had a lot of experience with compiling (Beyond using portage in gentoo), I've never really had any experience with developing for another CPU that wasn't x86 and that didn't have a HD. There are a lot of challenges to doing this. The challenges range from bootloaders to decided on a GUI.

As of writing this, I've got nothing substantial accomplished with the dev board other than I'm able to create a filesystem image and get a command prompt. I've only once been able to get X working, and I can't remember what xorg settings I found on the net that actually worked. Again, as I've said, all these sites are geared to work on the other board with different NAND and different display and touch panel. Also a lot of these sites are in Chinese or something similar which I can't read. My goal with this dev board is to try to build a filesystem using linux that is extremely fast but has a functional GUI.

A very close friend of mine had the idea of building a kitchen cookbook using this device and I thought it was a pretty good idea. But before I can get anywhere with that, I need to learn a lot more about the device and how to get linux up and going smoothly each and every time. So far even my writing of the filesystems to the NAND product different results each time. So it's a quirky process.

On this site I'll be sharing all the information I gather, whether it is right or wrong, I'll share what works for me and you can try it on yours and let me know whether it works.

I hope you enjoy my site and I hope that it provides you with whatever you need to get your Mini2440 or Micro2440 board going without all the headaches I've had to put up with.
