Greeting,

I'm learning on how to use the XMC Flash emulated EEPROM and I have studied the APP help of E_EEPROM_XMC1.

I configured the app as the help manual demonstrates, and used then build the same application code to run on my XMC1300 boot kit.

But how could I debug and verify those data I want to stored has already been stored to the right flash address? I'm thinking of using "memory view" to debug however nothing but "?????????" could be found on each columns like I posted below:

2128.attach

Any suggestion would be very appreciated!


regards,

Fender
