TDA4VM: Procedure for signing fitimage using binman in sdk9.2

HI Kishore

Can you refer to the fitImage.its present in the Default SDK , can you keep unsigned images instead of signed one also can you add bootscr along with kernal and fdt.

Regards
Diwakar

Hi Diwakar,

Thank you for your inputs.

We followed above suggestions now.

Now, it is going ahead, but our script functionality is not visible.

Getting the below error : 

Could not find configuration node
load of <NULL> failed
Working FDT set to 83000000
Loading Kernel Image

Thanks in advance.

Hi Diwakar,
One more observation, while building, we do not see our script- entry in default configuration log.
Kernel and fdt entry is visible as shown below.

Also the " Description: 2 Linux kernel, Boot Script, FDT blob" is getting updated in the log.

Also do not see, load address entry in Image 35 (script-1).

For your reference, we are attaching the updated fitImage.its file here.

/dts-v1/;
