PSoC6 SMIF HardFault(bus fault)

[Oxanagig3]

Hello, 

I am using a PSoC6 to interact with a serial flash, and I have encountered a bus fault using the library. The fault happens in the Cy_SMIF_TransmitCommand() function.

Here is some screenshots for the fault and the system clock configure.

I would like to know how to fix this issue? What was the cause of this issue?

Let me know if you need more information.

Thanks,

Xiang Gao

Hello @Oxanagig3,

It's tough to say from the screenshots why the error occurs. Would you be able to attach your project or a stripped-down version of the project? This will help us reproduce the issue and find the root cause. 

Also, are you using a custom board or a Cypress kit? Which memory chip are you interfacing with? 

Please attach the datasheet of the memory chip too.

Regards,
Dheeraj

I think I found the issue in my project.

If the Serial Flash was not initialized successfully, then this issue would happen.
