Original question:
what is the difference between the k3-j721e-common-proc-board.dtb and k3-j721e-common-proc-board-infotainment.dtbo?
is my understanding correct bl31.bin and bl32.bin are the part of the tispl.bin ? what about the .signed bin.
is there document available explaining the files present in the /home/uic68347/ti-processor-sdk-linux-j7-evm-08_00_00_08/board-support/prebuilt-images?
k3-j721e-common-proc-board.dtb
Is the actual device tree binary that comprises of all the DT nodes for J721e.
k3-j721e-common-proc-board-infotainment.dtbo
It is just an overlay on top of the k3-j721e-common-proc-board.dtb it will have very few nodes related to infotainment card.
is my understanding correct bl31.bin and bl32.bin are the part of the tispl.bin
Correct. Check the U-Boot file board/ti/j721e/README for all the details.
bl31.bin is ATF
bl32.bin is OPTEE
what about the .signed bin.
Those are for HS (High secure devices). You need not worry as you are using the GP(General purpose devices).
is there document available explaining the files present in the /home/uic68347/ti-processor-sdk-linux-j7-evm-08_00_00_08/board-support/prebuilt-images?
None. As such but.
