stm32f103 write/erase internal Flash

[Alexte]

With this configuration, writing or erase to the internal flash causes an error.

Code: Select all

#define STM32_HSI_ENABLED                   FALSE
#define STM32_LSI_ENABLED                   FALSE
#define STM32_HSE_ENABLED                   TRUE
#define STM32_LSE_ENABLED                   FALSE


If I resolve the internal and external clock, then everything works.

Code: Select all

#define STM32_HSI_ENABLED                   TRUE
#define STM32_LSI_ENABLED                   FALSE
#define STM32_HSE_ENABLED                   TRUE
#define STM32_LSE_ENABLED                   FALSE


Question. From which clock does the microprocessor work in this latter case?
External or internal?

There are other settings for that, you should show the whole clock section of mcuconf.h for me to tell, it depends on the settings of the various muxes and PLL.

Demos are all fed from HSE and PLL.
