Hi,I can't get the external loader to work in STM32G491.For the test, I replaced the bodies of the Init()/Erase()/Write() function with LED blinking. I did this to check if the functions are called correctly. For debugging, I used STM32_Programmer_CL...

Hi,I am working on an external loader for STM32G491.For STM32F4 series microcontroller, everything works fine, but STM32G491 does not work.I observed that the external loader program is loaded into RAM, but does not execute.I did some tests with runn...

I reduced the used memory and everything works properly.Every tutorial I've seen shows to uncheck 'Discard unused sections' ( to keep the compiler from removing unused code). But this results in including a lot of functions that are not needed at all...

I have done the test on the NUCLEO-G491RE. The result is the same.

Thank you for the reply.>> Does it load MT25QL512ABB_STM32G474E-EVAL.stldr ?Yes. Log attached below. QSPI config exactly as you wrote. >> Do you have a serial port?I have UART3 PB10:TX, PB11:RX (and RS485 USART1; PC4:TX; PC5:RX, PA12:DE). >> PD2 GPI...

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...

For now, the external loader does not support any memory only flashes an LED on PD2. Please see the attached files.The target memory is W25Q series connected via QSPI.I have done Erase, Read, Write, MemoryMappedMode tests and everything works fine. T...
