I downloaded the latest PLSDK 6.03.00.106 image and created an SD card to run the TIDL ssd_multibox example. However, trying to launch any of the matrix gui examples for me just crashes. Launching the ssd_multibox example returns:
TIOCL FATAL: Failed to open EVE message queue
I have tried to look at the remoteproc logs for EVE in /sys/kernel/debug/remoteproc/remoteproc0/trace0 but on my serial console this returns a bunch of non-ascii characters.
I also looked through my boot log and never see a confirmation that firmware is loaded on the DSPs or EVEs although there are firmware files in /lib/firmware/*ipu1* etc. However, I do not have any firmware files in /run/media/mmcblk0p1.
Finally I do see a couple messages from omap-mailbox:
[ 273.112854] omap-mailbox 48840000.mailbox: Try increasing MBOX_TX_QUEUE_LEN
[ 273.119967] omap-rproc 58820000.ipu: PM mbox_send_message failed: -105
I verified that CMEM is running on my EVM and there's only 2 EVEs on the AM5728 so I shouldn't need to increase CMEM size as per the documentation.
Any suggestions on what else I should try to get these examples running? I'm using the AM5728 IDK and have verified that the camera input works as expected.
