EEPROM data question

[gumu]

Hi NXP team,

I have a question about EEPROM data.

the platform is mm9z1-638.

I have wrote a data (0xaabbccdd) into address (0x10000) of EEPROM and try to check the value with CodeWarrior MEMORY tool, the values are 0. like below screenshot:

Confusingly, It's successful to read data at address(0x100000) after that.please refer to the below screenshot:

I'd like to know where the problem is.

Thanks!

Hello,

In some cases, the debugger's memory view might not automatically refresh or update the displayed content.

Could you try to perform manual refresh/ of memory view before read instruction is executed?

seem the original EEPROM area content is no updated.
