AM57xxevm Direct firmware load for dra7-ipu1-fw.xem4 failed with error -2

Other Parts Discussed in Thread: AM5728

When I boot the AM5728 evm board with prebuilt or a custom image generated with the SDK, I got an error with ipu-1 module loading. The error is the following:

remoteproc0: Direct firmware load for dra7-ipu1-fw.xem4 failed with error -2

I track it down and found that the problem is the dra7-ipu1-fw.xem4 file. In the target file system provided by TI the file structure of the lib/firmware directory is:

ti-processor-sdk-linux-am57xx-evm-02.00.00.00/targetNFS/lib/firmware$ tree
.

You can clearly see that this file is missing.

Where does can I found it? 

Thanks!

    Hi Daniel,

    Which SDK is this?  I use ti-processor-sdk-linux-am57xx-evm-02.00.01.07 and the ipu1 firmware is present in lib/firmware:

    x0155517@mms:~/ti-processor-sdk-linux-am57xx-evm-02.00.01.07/filesystem/tisdk-rootfs-image-am57xx-evm$ cd lib/firmware/

    Thanks for the answer. 

    I was using an older version of the TI SDK (version: ti-processor-sdk-linux-am57xx-evm-02.00.00.00) . That version does not have dra7-ipu1-fw.xem4 file.
