Working on a bootloader. Mapped SRAM of STM32F072 to 0x0000 0000... by setting SYSCFG_CFGR1_MEM_MODE accordingly. uVision (V5.24.2.0) "View Memory Windows" then shows correctly same contents at 0x0000 0000... ("Memory 1") and at 0x2000 0000... ("Memory 2"). Then manually modified 0x0000 0000... by changing values in "Memory 1" window. Surprisingly content in "Memory 2" window do not change. Is this a uVision problem?
