+    1. This example assumes that a network is connected.  During its
+       initialization, it will try to negotiate the link speed.  If you have
+       no network connected when you reset the board, there will be a long

+    2. This example supports the ADC test (apps/examples/adc) but this must
+       be manually enabled by selecting:
+
+       CONFIG_ADC=y             : Enable the generic ADC infrastructure
+       CONFIG_STM32_ADC3=y      : Enable ADC3
+       CONFIG_STM32_TIM1_ADC3=y : Assign timer 1 to driver ADC3 sampling
+
+       See also apps/examples/README.txt
+
+       General debug for analog devices (ADC/DAC):
+
+       CONFIG_DEBUG_ANALOG
+
+    3. This example supports the PWM test (apps/examples/pwm) but this must
+       be manually enabled by selecting:
+
+       CONFIG_PWM=y              : Enable the generic PWM infrastructure
+       CONFIG_STM32_TIM4_PWM=y   : Use TIM4 to generate PWM output
+
+       See also apps/examples/README.txt
+
+       Special PWM-only debug options:
+
+       CONFIG_DEBUG_PWM
+
+    4. This example supports the CAN loopback test (apps/examples/can) but this
+       must be manually enabled by selecting:
+
+       CONFIG_CAN=y             : Enable the generic CAN infrastructure
+       CONFIG_STM32_CAN1=y      : Enable CAN1
+       CONFIG_CAN_LOOPBACK=y    : Enable CAN loopback mode
+
+       See also apps/examples/README.txt
+ 
+       Special CAN-only debug options:
