Why cant i write into mem 0x40026410?

stm32f207zg (nucleo-f207zg)

But that memory addr cannot be written not with my init code nor manually trough the STM32IDE debugging tools .

Is there any memory protection or lock i am missing?

Hello @Javier Muñoz

Just a basic question: Did you enable the DMA2 clock ? (RCC_AHB1ENR bit 22) ?

(or call corresponding HAL/LL to do it)

Ding ding ding!, that was it.

Im using autogenerated CUBEMX code.

It looks like CubeMX places ADCDMA config after the DMA clock is enabled (RCC->AHB1ENR), so thats why it wasnt working

If i move the MX_DMA_Init before the ADC init everything works
