UCD3138A: Ucd3138A fusing issue

Part Number: UCD3138A

Dear TI,

I had fused one pcs UCD3138A, it can work.

But when I want to download FW to the chip  again , the chip go back to ROM.UI can not fuse the chip successful .

The GUI shows Error:Firmware Download Error; device did not pass factory trim check;

firmware has not been downloaded and the program flash checksum has been cleared on the device; any program present will NOT automatically start when the device is reset.

 

Each time  power up the chip, it stay in Rom state

 

What is means of that?

Does something wrong with the chip? or somting wrong with GUI?

 

Best Wishe
