PIC32MZ2048EFM144的UART2 ERROR INTERRUPT启用会导致崩溃

嗨，所有，我正在努力与PIC32 MZ2048 EFM144和突然崩溃（RCON 0x40 -软复位）几个星期。现在我得到了它的原因…当我启用UART2错误中断时，我启用和禁用了阴影ISR，在ISR优先级和软/自动等周围播放，但是无论我尝试什么，都能使IE结果在CPU崩溃中出现。奇怪的是当EIE＝0时，对于错误标记的投票，在RS232数据小时之后，没有人接受。但是总线上的相同数据和EIE＝1，经过几秒钟的数据和CPU崩溃。也许总线上有什么东西（我没有检查，因为我目前没有使用范围的权限），但是即使总线上存在一个真正的问题，为什么要在CPU崩溃时启用错误中断？我还使用IF＝0和VRead UrthWh（）-Gt的位置读取U2Reg并将其复制到内部RAM。此时IP＝6，使用IPL6SoT。但是汽车或是什么导致了同样的行为。这里有什么问题？

    Hi all,

I'm stuggling for weeks with the PIC32MZ2048EFM144 and suddenly crashes (RCON 0x40 - softreset).
Now I'v got the cause of it.. it's when I enable UART2 error interrupt.
I'v enabled and disabled the shadow ISR's, played around with ISR priorities and SOFT/AUTO etc. but whatever I try, enabling IE results in crashing of the CPU.
The strange thing is when EIE = 0, and polls for errorflags, after hours of RS232 data no one takes place.
But same data on the bus and EIE = 1 and after just a couple of seconds of data and the cpu crashes.
Maybe there is something on the bus (I didn't checked that because I have no abbility of using a scope at the moment), but even if there is a real problem on the bus, why crashes the CPU when enabling the error interrupt?
void vInitUart2(void)
{
    U2MODE = 0x0;
    ANSELGCLR = 0x0040;
    TRISGSET = 0x0040;
    U2STAbits.UTXEN = 0;
    U2STAbits.URXEN = 0;
    RPB14R = 0b0010; //RPB14R = U2TX
    U2RXR = 0b0001; //U2RX = RPG6
    //RPG6R = 0b0010;
    //U2RXR =
    //TRISBCLR = 0x4000;
    //TRISGSET = 0x0040;
    //TRISBSET = 0x4000;
    U2BRG = 53; //100Mhz --> 115k200
    U2STAbits.URXISEL = 0b00;
    U2TXIF;
    U2TXIE = 0;
    U2RXIF;
    IFS4bits.U2EIF = 0;
    IPC36bits.U2RXIS = 0;//2
    IPC36bits.U2RXIP = 7;
    IPC36bits.U2EIP = 6;
    IPC36bits.U2EIS = 0;//3
    IEC4bits.U2EIE = 1;
    U2RXIE = 1;
    U2MODEbits.ON = 1;
    U2STAbits.UTXEN = 1;
    U2STAbits.URXEN = 1;
    __XC_UART = 2;
}

void __ISR(_UART2_FAULT_VECTOR,ipl6SOFT) Usart2Fault(void)
{
    IFS4bits.U2EIF = 0;
    if(U2STAbits.FERR)
    {
UartData.ui32_FrameErrorCount++;
    }
    if(U2STAbits.OERR)
    {
UartData.ui32_OverflowCount++;
    }
    if(U2STAbits.PERR)
    {
UartData.ui32_ParityErrorCount++;
    }
    U2STAbits.OERR = 0;
    vReadUartHW(); //save data
    bRXError = TRUE;
}

I also played with the position of the IF=0 and vReadUartHW() -> reads U2REG and copies it to internal ram.
At this moment IP = 6 and using ipl6SOFT. But AUTO or whatever results in the same behaviour.
What is the problem here?
