It is a big patch for stm32f0x, see the fellow : 1. fix heap management for stm32f0xx(SRAM=8k) 2. add USART1, USART2 driver for stm32f051R8 3. fix finsh support for stm32f0x 4. fix board components initial for stm32f0x and open debug msg 5. add led driver(pc9) and test thread for stm32f0discovery board 6. add init thread for stm32f0x do components initial 7. add rcc initial for stm32f0x in rt_hw_board_init() 8. add print rcc freq information function the console output example is: SYSCLK_Frequency is 48000000HZ PCLK_Frequency is 48000000HZ HCLK_Frequency is 48000000HZ CECCLK_Frequency is 32786HZ ADCCLK_Frequency is 14000000HZ USART1CLK_Frequency is 48000000HZ I2C1CLK_Frequency is 8000000HZ SystemCoreClock is 48000000HZ initialize rti_start:0 done \ | / - RT - Thread Operating System / | \ 1.2.0 build Nov 15 2013 2006 - 2013 Copyright by rt-thread team do components intialization. initialize rti_board_end:0 done initialize rt_hw_led_init:32768 done initialize finsh_system_init:0 done finsh>>
