+The STM32F105 BSP, based on the STM32F4 BSP, is compiled according to 
+http://alanstechnotes.blogspot.fr/2013/03/setting-up-rtems-development.html
+
+Having compiled the toolchain, RTEMS is compiled for the STM32F105 BSP following
+http://s937484.blogspot.fr/2013/10/rtems-stm32f407-discovery-board-posted.html
+
+We run the example on Qemu supporting the STM32 architecture as described at: 
+https://github.com/beckus/qemu_stm32
+
+The trick is that, as indicated at ftp://ftp.rtems.eu/pub/rrr/RRR_Quick_Start_Guide_en.pdf, the
+console is connected to UART3. Qemu as found on the previous GIT site only implements UART2:
+edit hw/arm/stm32_p103.c to add both UART1 and UART3 by including
+
+    DeviceState *uart1 = DEVICE(object_resolve_path("/machine/stm32/uart[1]", NULL));
+    DeviceState *uart3 = DEVICE(object_resolve_path("/machine/stm32/uart[3]", NULL));
+    assert(uart1);
+    assert(uart3);
+    stm32_uart_connect((Stm32Uart *)uart1,serial_hds[0],STM32_USART1_NO_REMAP);
+    stm32_uart_connect((Stm32Uart *)uart3,serial_hds[2],STM32_USART3_NO_REMAP);
+
+having compiled Qemu with these updates, and RTEMS for the STM32F105 BSP, the example is loaded using
+
+qemu-system-arm -M stm32-p103 -serial stdio -serial stdio -serial stdio -kernel hello.bin
+
+(three times -serial stdio to indicate that all three UARTs outputs are displayed on stdout). The result is
+VNC server running on `::1:5900'
+LED Off
