Hi ,

 

I have a BF606  customized board with a TJA1042TK CAN transeiver.

I have a problem to enter this board to hibernate mode when choosing the wake up from CAN (the only way to wakeup my board is from CAN). I have integrated the can_pm_cache.patch.zip andcan_hibernate.patch.zipcan_hibernate.patch.zip.

I have done the follwing tests in my customized bords:



1. If I enable the wake from CAN, the board doesn't enter to hibernate but I can't send any CAN message to the board.

2. If I disable the wake from CAN, the board enters to hibernate mode but it can't wake which is normal.

I did  the same tests on the BF609 ezkit board (TJA1041 CAN transeiver) with same uImages:

1. If I enable the wake from CAN, the board enter to hibernate and if I send any CAN message it wakes.

2. If I disable the wake from CAN, the board enters to hibernate mode but it can't wake which is normal.


Is there any thing that must be changed whhile changing the CAN transeive?


Thank you
