[U-Boot-Users] Interrupt on at91sam9261ek for device keypad
by Pranav Desai 28 Dec '07

28 Dec '07

Hi, I am a newbie on u-boot development and am working on at91sam9261ek board. I needed the device keypad(keypad works on pio lines) to work with u-boot. I wrote a driver of sorts for this keypad. But got stuck at registering an interrupt for it. Although I eventually found a work around by polling the status registers and the keypad worked perfectly, I just wanted to know if it is possible to do so using interrupt handling ? As searching the list I came across many posts which said that u-boot does not support interrupt handling. If this cannot be done then do I have to do something manually in order for interrupt handling to work? Please enlighten me :) Thank you Pranav

[U-Boot-Users] bad magic number when loading kernel image from different location in flash
by Aparna Badve 28 Dec '07

28 Dec '07

Hello I get bad magic number when I try to load a kernel image from different location in flash rather than the default location using bootm command. I am successfully able to boot the image from address 0x60080000 but unable to boot the image from 0x60780000 in flash. can you tell me how to get rid of the bad magic error? Thanks and Regards Aparna --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo! Mobile. Try it now.
