Hi,
We are using AM57XX EVM, and we are running some operation on DSP using Opencl.
We are using ti-processor-sdk-linux-am57xx-evm-03.02.00.05 SDK and components in it (u-boot. kernel. etc).
We are getting error logs like mmu fault has been occurred. The logs are attached below.
After making hard power on & off, if we make DSP operation the error goes out.
Please suggest us to where to do change or not. Please help us.
Thanks,
Pankil

rpmsgThreadFxn: transportGet failed on fd 13, returned -20
TIOCL FATAL: Communication to a DSP has been lost (likely due to an MMU fault). Please wait while the DSPs are reset and the runtime attempts to terminate. A reboot may be required befo
re running another OpenCL application if this fails. See the kernel log for fault information.
