It seems that my post was misinterpretative.I'm not talking about the factory embedded DFU bootloader, which some microcontroller include. I'm talking about the software USB "DFU_standalone" example, provided by ST, which should work with any USB cap...

Hi @STOne-32,Thank you for replying. What two instructions do you exactly mean?Your article describes a procedure during power-down and during wake-up. In my case there is no wake-up event before using DMA.

New finding:During main while loop the CPU goes into low-power mode frequently. And wakes up every interrupt.PWR->CR = PWR_CR_CWUF | PWR_CR_LPSDSR; WFI();If I comment out these lines, DMA access to flash works.New questions:How can I get DMA access t...

Address is 0x08003064.Do FLASH registers need specific configuration?
