rt-thread启动网络协议栈后无法在uboot命令行中启动

[Surest]

硬件平台zynq7020，目前使用xilinx fsbl直接启动rt-thread内核正常，网卡正常
uboot 命令行启动rt-thread，正常启动后，协议栈发送arp请求时访问地址异常
信息如下：

根据pc与lr地址反汇编后，发现发送arp包时某个指针异常，但是函数调用过程中这个指针一直是正常的，突然间这个地址就无法被访问造成了data abort

由于不经过uboot使用真整个程序都正常，只有在uboot下会出现问题，网络协议栈是lwip

求问整个问题查找的思路，已经被折磨疯了

uboot 本身也是有网络驱动的，是否是也操作了寄存器导致让他thread 初始状态不对了
