【求助】 为什么jtag调试器调试一直报错,无法实现烧写

使用了自己的FPGA开发板,通过普通的IO实现jtag调试器连接,FPGA顶层的引脚如下图所示

其中qspi引脚用的是FPGA固化程序用的flash

而下载器则是通过淘宝上购买的一个sispeed USB转JTAG+UART的下载器

然后在nuclei studio上选择的是sdk-hbird_sdk @0.1.3

在点击debug图片alt按钮时总是会有各种报错,总是不能成功,试了无数次后只成功过一次半,其他均失败。而且每次报错信息还不一样
下面是各种报错信息

下面两张图是成功的那次的报错信息,是经过无数debug,然后某次串口突然停止输出了(平时一般一直输出0),然后按下mcu复位按键,就实现了下载成功,但也只成功过这一次

另外通过debug,在烧写FPGA程序时候,观察一下信号,inspect_pc一直处于0和2,然后nuclei studio下载后指令变化了,FPGA上观察到的指令值对比了一下.verilog文件的指令值是一样的,说明还是有程序写进去了,但是还是一直报错,串口也无法输出打印的信息

    换202212版试试看,08版的OpenOCD对蜂鸟的支持有点小问题

    也试过了,202212版本,还是一样报错,串口没有正常输出,一直低电平。
