I can't upload full project. Our business application is already developed. but I can upload partially related on this issue. What part would you like to check?

[_maibi]

could you let me know check points?

well this is a hardfault caused by a memory violation. You need to be able to get the PC address of the instruction that caused this violation. There are a lot of threads in this forum that will help you debug hardfault to get the address of the instruction that caused this. After you get to the code we can then discuss to see if you are doing something wrong or if there is any workaround. For now without knowing where and how this memory violation happens, there is nothing much I can help with.
