BBB Board running Angstrom v2012.12 and Linux beaglebone 3.8.13 #1 SMP Tue Jun 18 02:11:09 EDT 2013 armv7l GNU/Linux
Trying to run command "echo <overlay> > $SLOTS" results in error "-su: echo: write error: No such file or directory" I can "cat $SLOTS" (/sys/devices/bone_capemgr.8/slots) just fine. I am root and root has rw on that file.. I'm trying to get my own overlay working for a very simple no-eeprom cape which has a DS1307 (which works fine, btw) and which will have an HD47780 LCD. I have a number of pre-built overlays in /lib/firmware and none of them will load. An example from dmesg: [ 330.631832] bone-capemgr bone_capemgr.8: failed to load firmware 'cape-bone-adafru-00A0.dtbo' [ 490.071059] bone-capemgr bone_capemgr.8: part_number 'cape-bone-adafruit-lcd-00A0', version 'N/A' [ 490.071138] bone-capemgr bone_capemgr.8: slot #11: generic override [ 490.071157] bone-capemgr bone_capemgr.8: bone: Using override eeprom data at slot 11 [ 490.071175] bone-capemgr bone_capemgr.8: slot #11: 'Override Board Name,00A0,Override Manuf,cape-bone-adafru' [ 490.071277] bone-capemgr bone_capemgr.8: slot #11: Requesting part number/version based 'cape-bone-adafru-00A0.dtbo [ 490.071296] bone-capemgr bone_capemgr.8: slot #11: Requesting firmware 'cape-bone-adafru-00A0.dtbo' for board-name 'Override Board Name', version '00A0' [ 490.080114] bone-capemgr bone_capemgr.8: failed to load firmware 'cape-bone-adafru-00A0.dtbo' Is it failing due to lack of an eeprom? My LCD project is using code from here: LCD library: http://www.nunoalves.com/open_source/?p=152 (git repo https://github.com/nunoalves/BeagleBone_IO_lib) It looks like in the code (which fails on asserting GPIO pins) tries to set up the pins itself. Should an overlay even be needed? I have plenty of unix experience but not so much BBB-specific, so bear with any obvious oversights on my part please. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
