jlink 下载 keil debug问题新手求助

[aaron1430]

先交代一下芯片和环境软件信息：
芯片：STM32F103C8T6
J-FLASH：V4.90
keil：4.12

烧写方法：keil编译后通过J-Flash下载到单片机

问题是这样的，程序修改编译后烧写都正常，但修改后第一次烧写程序不能完成预期功能，但是只要用keil debug过之后不管有没有重新烧写都一切正常。请大神帮忙分析一下到底是什么问题？
想过要用串口打印，什么信息都不输出，但是debug过后就能正常输出了。

问题解决了，不是debug的问题，是jlink插上之后会给cc1101供电。我这个板子有个cc1101模块，主要问题也是出在不能正常通信。 就是说除了板子的电源以外单独给cc1101供电就能正常通信。修改方法是供电之后用cc1101发送一次数据，再冲洗发送缓冲。 void CC1101SendPacket(uint8_t *txBuffer, uint8_t size,uint8_t count) { CC1101_send_Cmd(CC1101_SFTX); CC1101_Write_Reg(CC1101_TXFIFO, size); CC1101_Write_Burst_Reg(CC1101_TXFIFO, txBuffer, size); CC1101_send_Cmd(CC1101_SFTX); }
