中断问题

各位大神：本人使用STVD开发中断，但是在编译的过程中总是显示无效指针。操作如下，struct interrupt_vector const _vectab[] = {
{0x82, (interrupt_handler_t)_stext}, /* reset */
{0x82, NonHandledInterrupt}, /* trap  */
{0x82, NonHandledInterrupt}, /* irq0  */
{0x82, NonHandledInterrupt}, /* irq1  */
{0x82, NonHandledInterrupt}, /* irq2  */
{0x82, NonHandledInterrupt}, /* irq3  */
{0x82, NonHandledInterrupt}, /* irq4  */
{0x82, NonHandledInterrupt}, /* irq5  */
{0x82, NonHandledInterrupt}, /* irq6  */
{0x82, NonHandledInterrupt}, /* irq7  */
{0x82, NonHandledInterrupt}, /* irq8  */
{0x82, NonHandledInterrupt}, /* irq9  */
{0x82, NonHandledInterrupt}, /* irq10 */
{0x82, NonHandledInterrupt}, /* irq11 */
{0x82, NonHandledInterrupt}, /* irq12 */
{0x82, NonHandledInterrupt}, /* irq13 */
{0x82, NonHandledInterrupt}, /* irq14 */
{0x82, NonHandledInterrupt}, /* irq15 */
{0x82, NonHandledInterrupt}, /* irq16 */
{0x82, NonHandledInterrupt}, /* irq17 */
{0x82, NonHandledInterrupt}, /* irq18 */
{0x82, NonHandledInterrupt}, /* irq19 */
{0x82, NonHandledInterrupt}, /* irq20 */
{0x82, UART2_RX_IRQHandler2}, /* irq21 */
{0x82, NonHandledInterrupt}, /* irq22 */
{0x82, NonHandledInterrupt}, /* irq23 */
{0x82, NonHandledInterrupt}, /* irq24 */
{0x82, NonHandledInterrupt}, /* irq25 */
{0x82, NonHandledInterrupt}, /* irq26 */
{0x82, NonHandledInterrupt}, /* irq27 */
{0x82, NonHandledInterrupt}, /* irq28 */
{0x82, NonHandledInterrupt}, /* irq29 */
};
在中断21处添加UART的RX中断，产生的原因是什么，求大神解答？

{0x82, (interrupt_handler_t)UART2_TX_IRQHandler}, /* irq20 - UART2 Tx interrupt */
{0x82, (interrupt_handler_t)UART2_RX_IRQHandler}, /* irq21 - UART2 Rx interrupt */
按这个写一下试试另外不是每一款stm8的片子都有UART2 再次 it.h conf。h等文档都得加上去缺一不可另外官方有example 把里面的东西复制过来就好啦自己写多累。。。
