PROCESSOR-SDK-AM57X: Big Data IPC Example fails to opem DMA-BUFF and make rule for SDK has been removed in SDK 9.03

Tool/software:

Hello,

I am currently running through instructions listed in the RTOS SDK release notes for Big Data IPC Example. I am currently working on the am57x beagleboard-x15.

I followed the instructions listed here: https://software-dl.ti.com/processor-sdk-rtos/esd/AM57X/09_03_00_00/exports/docs/rtos/index_examples_demos.html#how-to-run-the-example 

The logs below show the error I ran into:

As you can see I successfully sym linked the simple_buffer firmware to dsp1. When I tried hosting the new firmware I was met with the "Failed to open DMA-BUF" error.

I then tried to rebuild the project by following the instructions listed here: https://software-dl.ti.com/processor-sdk-rtos/esd/AM57X/09_03_00_00/exports/docs/rtos/index_examples_demos.html#how-to-re-build-the-example

When I ran the "make big-data-ipc-demo" command I was met with the following:

jsava@laptop-183:/export/home/jsava/ti-processor-sdk-linux-am57xx-evm-09_03_06_05$ make big-data-ipc-demo
make: *** No rule to make target 'big-data-ipc-demo'.  Stop.

It looks like the big data recipe was installed into the filesystem, but the make rule was removed in SDK 9.03

Please let me know if I am messing up any steps. Thank you for the help!

Best,
