[调试] JTAG下运行正常，从QSPI或者SD卡启动则无响应，如何查找问题

一、问题现象
二、用自定义fsbl替代系统默认的fsbl
- 1. 新建fsbl_new
- 2. 如果提示缺少xilffs库
- 3. 使能调试信息输出
三. 启动成功和失败情况下的典型输出
- 1. JTAG启动模式: 正常加载
- 2. QSPI启动模式
- - 2.1 正常加载: flash已经烧写正常运行的程序，启动模式QSPI
  - 2.2. QSPI错误加载的例子
- 3. SD卡启动模式
- - 3.1 SD正常启动
  - 3.2 没插卡或者卡检测失败
  - 3.3 找到文件但是文件错误

一、问题现象

用jtag在ide里面调试运行都正常。
生成boot.bin烧写到flash后，上电pl done不亮，串口无打印输出

二、用自定义fsbl替代系统默认的fsbl

1. 新建fsbl_new

新建一个app，选择Zynq FSBL模板。
在这里插入图片描述

2. 如果提示缺少xilffs库

在上面的情况，有可能会提示bsp缺少xilffs库。
这时候返回到bsp界面，勾选添加缺少的库，并重新编译全部工程。再执行上面的新建步骤

在这里插入图片描述

3. 使能调试信息输出

打开新建的工程，找到fsbl_debug.h
可以看到#if defined (FSBL_DEBUG_INFO)这行，
只要我们定义了FSBL_DEBUG_INFO，就会输出完整调试信息

因此，在36行增加

#define FSBL_DEBUG_INFO

然后重新编译fsbl_new
在这里插入图片描述

三. 启动成功和失败情况下的典型输出

1. JTAG启动模式: 正常加载

把启动模式切换到JTAG，然后运行fsbl_new，结果如下：

Xilinx First Stage Boot Loader 
Release 2020.1  Jul  2 2024-12:27:50
Devcfg driver initialized 
Silicon Version 3.1
Boot mode is JTAG

2. QSPI启动模式

2.1 正常加载: flash已经烧写正常运行的程序，启动模式QSPI

先烧写QSPI，然后断电，把启动模式切换到JTAG。重新上电，在Vitis里面运行fsbl_new，结果如下：

2.2. QSPI错误加载的例子

给QSPI烧写一个错误的文件。然后运行

Xilinx First Stage Boot Loader 
Release 2020.1  Jul  2 2024-12:27:50
Devcfg driver initialized 
Silicon Version 3.1
Boot mode is QSPI
Single Flash Information
FlashID=0x1 0x20 0x18
SPANSION 128M Bits
QSPI is in Dual Parallel connection
QSPI Init Done 
Flash Base Address: 0xFC000000
Reboot status register: 0xF058200C
Multiboot Register: 0x0000C400  //这里识别错误，C400对应到flash的末尾了。正常应该是C000
Image Start Address: 0x02000000 //这里计算出的偏移地址已经超过了flash，肯定无法读出正常的程序
DATA_ABORT_HANDLER              //报错：数据异常
FSBL Status = 0xA304            //在fsbl.h里面可以查到对应的宏定义#define EXCEPTION_ID_DATA_ABORT_INT	0xA304 /**< Data Abort Exception */

搜到Multiboot Register，可以搜到下面的代码，可以看到是由于没搜到正确的boot，导致MultiBootReg的值不正确。

		/** read the multiboot register*/MultiBootReg =  XDcfg_ReadReg(DcfgInstPtr->Config.BaseAddr,XDCFG_MULTIBOOT_ADDR_OFFSET);fsbl_printf(DEBUG_INFO,"Multiboot Register: 0x%08lx\r\n",MultiBootReg);/** Compute the image start address*/ImageStartAddress = (MultiBootReg & PCAP_MBOOT_REG_REBOOT_OFFSET_MASK)* GOLDEN_IMAGE_OFFSET;
