有关UART1的使用，我怎么调都调不过，这边问问大家有什么办法不？

问题１．UART1发送，只能在开机的第一次可以发送第一个字节，
以后在查询发送寄存器的时候，总是为不空的，然后就不能再发送了
芯片是R8C/2B，片内震荡20MHz，相似的配置在ＵＡＲＴ０是可以正常使用的

问题２．还有个关于编译器的问题，提示信息：
H:\Workspace\IIIB_0806\IIIB_0806\sect30.inc(112) : Warning (ln30): H:\Workspace\IIIB_0806\IIIB_0806\Debug\ncrt0.r30 : 'ROMDATA' section 'vector' is overlapped on the 'program' from FEDCH to FEDCH
H:\Workspace\IIIB_0806\IIIB_0806\sect30.inc(185) : Error (ln30): H:\Workspace\IIIB_0806\IIIB_0806\Debug\ncrt0.r30 : 'ROMDATA' section 'fvector' is overlapped on the 'program' from FFDCH to FFFFH

相似的位置还有 section “rom_FE”,“rom_FO”
前面有个相关的帖子是也是这样的错误,但是我这边不知道怎么解决掉这个问题,
sect30.inc文件中,除了中断地址之外我是没有修改的.
