STM32L0 EEPROM and DMA

Question asked by MaximeJ on Mar 2, 2016

Hello,

I'm using the internal EEPROM on a brand new STM32L021.

In order to save some data into that EEPROM in an "asynchronous" way, I use DMA1 channel 1 in MEM2MEM configuration.
My issue is that as soon as DMA_CCR_EN bit is set, the execution freeze until the data has actually been writen. So the behaviour is the same as if I had used a program "load and store".
Is there any trick or information I didn't notice ?
