Tool/software: Linux
Dear Experts,
I have built the latest SDK :
Boot the linux with SD card from rt-linux, during the login, it will display the mmu1_dsp1: wait_target_disable failed error:
[24.070866] omap_hwmod: mmu1_dsp1: _wait_target_disable failed
Log is list as bellow:

[ 24.085029] omap_hwmod: mmu0_dsp1: _wait_target_disable failed
Then I run the OpenCL example code, float_compute, it seems failed. Some log is listed as bellow:
root@am57xx-evm:~# ls
dual_camera log.txt log_mod.txt ov2659.ko
float_compute log_camera.txt nemo
root@am57xx-evm:~# ./float_compute
This example computes y[i] = M[i] * x[i] + C on single precision floating point2
- Computation on the ARM is parallelized across the A15s using OpenMP.
- Computation on the DSP is performed by dispatching an OpenCL NDRange kernel a.

It seems the DSP doesn't work.
