Hi Txema,

I will indeed use your patch. But I would also like to have some pointers as to how to develop this patch. I am new to the embedded world although not that new to Linux. I want to fully port U-boot to CSB535FS as we require the support for SD card and Compact Flash.

How do I start porting U-Boot to a new board? I have read the README of U-Boot. And I know that I need to set a lot of parameters - but they are Greek and Latin for me. How do I start off? Any web sites?? Books?? Links?? Were do I get these parameters from?? From the board manufacturer / supplier??

Thanks and Regards, Midhun Agnihotram.

Hi Txema,

I got the patch and I have gone through the conversation - when you submitted the patch. But I did not really understand the "threats". What is all about.

The discussion was about how the patch must be done to be accepted and more exactly where to put the porting related code in the U-Boot directory tree.

...

Is porting U-Boot to CSB535 not advised??

I don't think so. We have developped a CSB535 based custom board and U-Boot is working fine.

...

Or is it that there is more work to be done??

The patch has not support for USB, SD Card or CF, but you can launch a linux kernel from flash or tftp.

Thanks & Regards, Midhun Agnihotram,

Hi Midhun,

I sent a patch for a U-Boot 1.2.0 version but It was not accepted. See the threats "Support for csb535fs / i.MX21 LiteKit" and "arm SoC code in U-Boot". I pushed this work in my "todo stack" but unfortunately it's still there (And I'm afraid It will be for long time). The patch It's working fine and you can get it from the U-Boot users mailing list or I can resend it to you.

Best Regards

J.M. Lopez.
