cc2640r2+ads1299–4ms一次中断，中断里面用spi去读取5个字节，系统就挂了

请教一下，我是用cc2640R2通过spi链接ads1299。初始话好后，ads1299通过一个io每4ms中断一下2640,2640在中断里面去读取ads1299的数据数据一共5个字节。

大概几秒后，2640就挂了。不知道问题出在哪里？

先谢了！

当机是我暂停了调试工具，按照网上的说法是发生了一个硬件的异常中断，有以下可能，我想问问如何修改堆栈？

Most exceptions falls into three categories:

Stack overflow or corruption leads to arbitrary code execution.

Almost any exception is possible.

A NULL pointer has been dereferenced and written to.

Typically (IM)PRECISERR exceptions

A peripheral module (like UART, Timer, and so forth) is accessed without being powered.

Typically (IM)PRECISERR exceptions

SPI 没有正确配置好吧，请参考官方文档【CC2640R2F通用】：dev.ti.com/…/_s_p_i_c_c26_x_x_d_m_a_8h.html
