Hi, I am currently testing the patchset 20160804 and encountered a problem introduced by 0005-Support-for-multiple-mailbox-protocols.patch. It's not possible to retrieve the data via the libraries "ecrt_voe_handler_data" function anymore after a successful ecrt_voe_handler_read. I still get the correct data size but there is no data found at the returned pointer address.
I guess this is the problem: "The mailbox state machines will check and fetch the data from their own buffer instead of the datagram buffer (that is no longer used for mailbox read data)." The data seems to be stored somewhere else now and the function still returns a pointer to a datagram buffer. Communication still works and the data is there inside the master as debuglevel=1 prints the correct data into the kernel log. I found the lines were this is done in the new introduced "ec_voe_handler_state_read_response_data", but how can I access the data from the library without using ioctl calls from my user application? I would appreciate any hint or an update of the patch.
