1. 修改MCU型号 
5. 自己编写startup_gd32f3x0.S准确性待验证
scons -cscons --dist发现GD32F330已经生效了。
5. 自己编写startup_gd32f3x0.S准确性待验证 ;/*; * Copyright (c) 2006-2021, RT-Thread Development Team; *; * SPDX-License-Identifier: Apache-2.0; *; * Change Logs:; * Date Author Notes; * 2018-05-22 tanek first implementation; */.syntax unified.cpu cortex-m4.fpu softvfp.thumb.global g_pfnVectors.global Default_Handler .section .isr_vector,a,%progbits .type g_pfnVectors, %objectg_pfnVectors: .word _estack // Top of Stack .word Reset_Handler // Reset Handler .word NMI_Handler // NMI Handler .word HardFault_Handler // Hard Fault Handler .word MemManage_Handler // MPU Fault Handler .word BusFault_Handler // Bus Fault Handler .word UsageFault_Handler // Usage Fault Handler .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word SVC_Handler // SVCall Handler .word DebugMon_Handler // Debug Monitor Handler .word 0 // Reserved .word PendSV_Handler // PendSV Handler .word SysTick_Handler // SysTick Handler // external interrupts handler .word WWDGT_IRQHandler // 16:Window Watchdog Timer .word LVD_IRQHandler // 17:LVD through EXTI Line detect .word RTC_IRQHandler // 18:RTC Wakeup through EXTI Line .word FMC_IRQHandler // 19:FMC .word RCU_CTC_IRQHandler // 20:RCU and CTC .word EXTI0_1_IRQHandler // 21:EXTI Line 0 and EXTI Line 1 .word EXTI2_3_IRQHandler // 22:EXTI Line 2 and EXTI Line 3 .word EXTI4_15_IRQHandler // 23:EXTI Line 4 to EXTI Line 15 .word TSI_IRQHandler // 24:TSI .word DMA_Channel0_IRQHandler // 25:DMA Channel 0 .word DMA_Channel1_2_IRQHandler // 26:DMA Channel 1 and DMA Channel 2 .word DMA_Channel3_4_IRQHandler // 27:DMA Channel 3 and DMA Channel 4 .word ADC_CMP_IRQHandler // 28:ADC and Comparator 0-1 .word TIMER0_BRK_UP_TRG_COM_IRQHandler // 29:TIMER0 Break,Update,Trigger and Commutation .word TIMER0_Channel_IRQHandler // 30:TIMER0 Channel Capture Compare .word TIMER1_IRQHandler // 31:TIMER1 .word TIMER2_IRQHandler // 32:TIMER2 .word TIMER5_DAC_IRQHandler // 33:TIMER5 and DAC .word 0 // Reserved .word TIMER13_IRQHandler // 35:TIMER13 .word TIMER14_IRQHandler // 36:TIMER14 .word TIMER15_IRQHandler // 37:TIMER15 .word TIMER16_IRQHandler // 38:TIMER16 .word I2C0_EV_IRQHandler // 39:I2C0 Event .word I2C1_EV_IRQHandler // 40:I2C1 Event .word SPI0_IRQHandler // 41:SPI0 .word SPI1_IRQHandler // 42:SPI1 .word USART0_IRQHandler // 43:USART0 .word USART1_IRQHandler // 44:USART1 .word 0 // Reserved .word CEC_IRQHandler // 46:CEC .word 0 // Reserved .word I2C0_ER_IRQHandler // 48:I2C0 Error .word 0 // Reserved .word I2C1_ER_IRQHandler // 50:I2C1 Error .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word USBFS_WKUP_IRQHandler // 58:USBFS Wakeup .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word DMA_Channel5_6_IRQHandler // 64:DMA Channel5 and Channel6 .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word 0 // Reserved .word USBFS_IRQHandler // 83:USBFS .size g_pfnVectors, .-g_pfnVectors .section .text.Reset_Handler .weak Reset_Handler .type Reset_Handler, %functionReset_Handler: ldr r1, _sidata ldr r2, _sdata ldr r3, _edata subs r3, r2 ble fill_bss_startloop_copy_data: subs r3, #4 ldr r0, [r1,r3] str r0, [r2,r3] bgt loop_copy_datafill_bss_start: ldr r1, __bss_start ldr r2, __bss_end movs r0, 0 subs r2, r1 ble startup_enterloop_fill_bss: subs r2, #4 str r0, [r1, r2] bgt loop_fill_bssstartup_enter: bl SystemInit bl entry /* Exception Handlers */ .weak NMI_Handler .type NMI_Handler, %functionNMI_Handler: b . .size NMI_Handler, . -
