BBB Cape handling

Hey Guys

I have a strange problem with the handling of my custom cape on the BBB.
My cape don’t have a EEPROM because it’s a prototype.

The first error appears in the capemanager:

[ 0.718342] bone-capemgr bone_capemgr.9: slot #6: BB-BONELT-HDMIN conflict P8.45 (#5:BB-BONELT-HDMI)
[ 0.727943] bone-capemgr bone_capemgr.9: slot #6: Failed verification

After the boot and log in and after ~60sec, a new error message appears and the BBB is in a faultstate (it crashes and doing nothing):

root@beaglebone:~# [ 120.521224] INFO: task kworker/u:1:21 blocked for more than 60 seconds.
[ 120.528386] “echo 0 > /proc/sys/kernel/hung_task_timeout_secs” disables this message.
[ 120.536854] Kernel panic - not syncing: hung_task: blocked tasks
[ 120.543292] [] (unwind_backtrace+0x1/0x9c) from [] (panic+0x59/0x15c)
[ 120.552003] [] (panic+0x59/0x15c) from [] (watchdog+0x19d/0x1c0)

[ 120.568610] [] (kthread+0x6b/0x78) from [] (ret_from_fork+0x11/0x34)

My questions are:

  • what the trigger of the second error message is?
  • What is the kworker/u:1:21?
  • Is the first error message relevant?
  • How can I fix this trouble?
  • How does the BBB detecting Capes (to understand which Pin could interrupt)?

Thanks for your help!


In the Picture (attachement) you can see the pinout of P8 and P9.
