STM32 flashes after flashing code without R / W protection

I have experience using the StdPeriph libraries for stm32 programming. But now I tried STM32Cube HAL with the STM32CubeMX code generator. I created a project with the following parameters:

  • Middleware: FreeRTOS and FatFS via SDIO
  • The compiler is GCC
  • stm32f103ret6 MCU

I imported the generated code into an Eclipse environment. I made binary code and flashed it using "st-flash write ...", as usual. My test program successfully wrote "Hello" to USART1 in a loop - this is not a problem. But then, when I tried to flash another code, it failed with an “unknown id chip”. If I manually connect NRST to GND, st-flash gives:

...Flash: 0 bytes (0 KiB) in pages of 2048 bytes

Full conclusion:

2015-06-14T16:07:29 INFO src/stlink-common.c: Device connected is: F1 High-density device, id 0x10036414
