TMS320F280025C: C2000 GANG about the ERROR 25 : Blank check err

Part Number: TMS320F280025C
Other Parts Discussed in Thread: UNIFLASH, C2000-GANG

Hi Champs,

I am asking for my customer.

The customer uses the same operation, two of the four GANG devices can be used normally, one of them cannot supply power to the MCU normally, and the other cannot pass the Blank Check as below. Under the same procedure, the GANG configuration is also the same. Why can't the Blank Check pass normally the below C2000 GANG? Any suggestion/Dir?

1.The other C2000 GANG cannot pass the Blank Check as below, check the power supply is normal.

2.We also have try the C2000 ware simple example still have the same error as below figure. So, under what circumstances can this error be caused? or how to debug this C2000 GANG. Thanks~
