I have updated STM32CubeIDE to Version: 1.17.0The same problem still occurs. ST-Link does not load external loader into RAM before calling Init() / Erase() / Write() function. [6.855] spawnCubeProgrammer(): 21:21:18:438 Memory Programming ... [6.855...

I have done an additional test.In the bodies of the Init(), SectorErase(), Write() functions, I placed code that flashes an LED. Now if any external loader function is called by ST-LINK I know it because the LED flashes.What did I observe?For STM32F4...

Sorry for the confusion, I forgot to write that the problem with starting the program from RAM has been solved.The problem was due to a bad VTOR setting.And an error in the linkerRAM (xrw) : ORIGIN = 0x20000004, LENGTH = 112KIt should beRAM (xrw) : O...

The problem is that the debugger/programmer/ST-LINK does not load the external loader into RAM before calling the Init(), SectorErase(), Write() functions. (Or, I'm wrong).From .map file I know that the Init() function of the external loader is at a...
