[beagleboard] Re: Watchdog timer and boot process
Thanks for the reply. These are the U-boot versions according to the log in the debug console Rev C: U-Boot 2014.04-rc2-00015-g99288ca (Mar 12 2014 - 09:49:41) Rev B:U-Boot 2013.04-dirty (Jul 10 2013 - 14:02:53) On Friday, June 13, 2014 2:50:26 PM UTC-3, Francisco Aguerre wrote: Hi, I've been working with both BBB rev B and rev C with the QNX BSP.

So after adding a line that starts a process wich kicks the wtd before it overflows, everything worked just fine. My question is: What could be the difference between the two platforms? Could it be that the u-boot in my rev C kicks the watchdog or something like that?

Ok, I tried that. Copyed the MLO/u-boot from B to C and it doesn't reset itself. So it's probably a thing of the u-boot after all. Is this supposed to be a bug? I've searched the forum before posting and no one has reported this kind of problem. Or maybe it's just that the OS initialization has to deal with the watchdog properly, which I didn't consider. Thanks for the help. On Friday, June 13, 2014 2:50:26 PM UTC-3, Francisco Aguerre wrote: Hi, I've been working with both BBB rev B and rev C with the QNX BSP.

There's not a lot of qnx users and the C with the new factory bootloader just began shipping last month..

Well, if found this: http://git.denx.de/?p=u-boot.git;a=commit;h=6843918e0035bf06cb65ad2b4c98b38e86e43bd5 Apparently, since that commit, the watchdog is enabled by default by the bootloader. Makes sense, as my B version had an older u-boot. Guess that the OS has to deal with it.
