following the manual, I was successful to bring up mini2440 with pengutronix bsp I am using ptxdist-2013.09.0.tar.bz2 OSELAS.BSP-Pengutronix-Mini2440-2013.10.0.tar.gz OSELAS.Toolchain-2012.12.1.tar.bz2 It does not have some device files in /dev folder, which exist in original 2440, such like buttons, my question is how can I create those device file. I know I need some files in original mini2440 kernel, how to merge them into new 3.11 kernel? Thanks
Just a suggestion to try; look at the patch files for an older BSP, say 3.7 and see if there is something in there you want. Copy that patch file to the newer BSP folder and then to get it work you add an entry to the file called <series> It has been awhile since I did this so no guarantees! Actually looking at the series file in both BSPs should show you what to do. Also, have you searched on the gmane site for PTXdist mini2440?
Craig, some of the device nodes in /dev are FA specific, but not Linux mainline. All these CPU specific features are present, but differently than FA did (the buttons are now regular input devices for example, without the need for a specific driver, same for the ADC, read the "special notes" in the manual).
Don't use kernels 3.11 or 3.10. They are broken for the s3c2440. Use a later or earlier version. See the 'known issues' in the BSP download page from Pengutronix for the details. Guillermo
