TDA4VM: single camera example failed to run on Newer TDA4VM silicon version.

user782719

Part Number: TDA4VM

Hi, Ti expert;

We are using SDK7.0, and vision demo run well on our custom board v1. Recently, we made a

newer version, the same "single camera demo" example (same sdcard image) can not run, the

single example seems blocked at following line.

status = vxVerifyGraph(obj->graph);

PS; old chip (left: XJ721EGALF) new chip on new board ( right: XJ721EGBALF)

what difference between these two version of silicon; will the difference cause the issue?

We tested tidl demo, it runs OK.

Thank you.

Hi,

Are you using silicon revision ES1.1? If this is the case, can you use later release, as ES1.1 silicon is not supported on SDK7.0 release.

We try SDK8.0 on our new board (with the new ES1.1 chip), it can not boot.

Please refer attached image.

(same sdcard with sdk8.0 works well on old boards with old chip.)

Hi,

It should just boot as it is, as both seems to be GP devices and there is no difference for GP.. system firmware seems to be booted correctly.

Are you sure that the SPL file is correct?
