You can use google to find my blog and forum by searching for bill and mini2440

Where can i download the files used in this tutorial. On the website, the link for download seems to be broken. Thanks in advance

I'm not sure that it does. I've tried numerous times to follow all these compiling guides to get u-boot working. I've managed to get a few images I found on the net that people have compiled, to work, but none of the ones I've compiled work correctly. I'm convinced that u-boot is written poorly, and buserror's modifications are specific for the 64MB boards.

u-boot is written poorly? I am afraid u-boot is the most popular open source embedded bootloader now.

And, of course, the modification is for 64MB boards only. O/w, how can you specify the addresses?

[superslammer]

@forrestbao popular doesnt make it better. There are 4million different versions floating around of which hardly any work reliably. I managed to solve my problem. It the latest buserror code, in include/configs/mini2440.h ... you comment out the IRQ line and write it to ram. that disables USB... once you get it in RAM, you can compile new one with that on, and flash your new one over the top of your old one from insie U-Boot...

[superslammer]

@superslammer But yes... U-Boot is, like everything else written for linux, half done, broken, and you're not expected to get upset about it. This is why enterprise doesnt fully embrace Linux. I love to TINKER... but not to the point where it drives me crazy just getting something to boot up. -- I'll be putting up a page soon with all my findings. It took me age s to collect all the info I have on the Mini2440 and Micro2440.

[forrestbao]

yeah, I will be very grateful if you could link your page in your next reply, such that other new comers of mini2440 can save time. But i really didn't compile u-boot at all. I used the image from KernelLab. I do not understand why you got so many troubles.

@superslammer

Its called......learning, do you honestly think that every piece of hardware and software you buy out of the box works no problem, thousands of man hours bring those things to you, try writing some drivers for Windows..............I have no hair anymore.

[superslammer]

@donnyab Whatever you say. None of us have the experience you do, we're all just idiots.

@superslammer

I didn't say you were an idiot mate....it is just that I always thought the point of Linux was that it is unfinished and imperfect and waiting for improvement maybe by someone like you. I am about to try to get this working on Blackfin, printing off the whole "manual" now - so maybe I can mail you for some help over the next few weeks........

[forrestbao]

I am not sure. I haven't gotten 128MB version.
