DLPC3478: API operation problem

Part Number: DLPC3478

Tool/software:

Hello,TI team
We know that DLPC3478 firmware has been updated to version 9.X, and it needs to match GUI version 3.2.X or above before it can be used normally.
In version 9.X of DLPC3478 firmware, a parameter PatternSetEntryIndex has been added to the timing table. On DLPC3478API, by adding this parameter, the API can run through.
However, there is still a problem that the "Program and Load Pattern" function of the API cannot be used normally. The following is a screenshot of the code.

If we downgrade the firmware and use version 7.X, the "Program and Load Pattern" function of API can be used normally.

So I guess, maybe 3478 firmware version 9.X, the code has been modified, and then the API needs to be modified synchronously before it can be used normally.

However, I just downloaded DLPC3478 API again from TI.COM, and found that it was still the old version DLPC-API-1.10. Without the new API, it will be more difficult for me to solve this problem.

Therefore, I need to know what the API needs to modify to ensure the normal use of the "Program and Load Pattern" function.
I asked the TI team to help me verify and solve it. Thank you.
