Keil Version for ADuCM310

Hi team

I saw an error while downloading AduCM310 MCU using Keil compiler.
When you turn on the power and download it, you can see the error below.

After that, if you repeat the download, it continues to work well.
Turn on the power and an error comes out only once.
The capacity of the Hexa file is about 23KB.
I doubt the version of Keil.
Because it worked well in the other version.
Please let me know if you have a Keil version you recommend.

Bad version for ADuCM310.
