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。 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 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 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 JTAG2. 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 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 FlashID0x1 0x20 0x18 SPANSION 128M Bits QSPI is in Dual Parallel connection QSPI Init Done Flash Base Address: 0xFC000000 Reboot status register: 0x60500000 Multiboot Register: 0x0000C000 Image Start Address: 0x00000000 Partition Header Offset:0x00000C80 Partition Count: 3 Partition Number: 1 Header Dump Image Word Len: 0x00080B00 Data Word Len: 0x00080B00 Partition Word Len:0x00080B00 Load Addr: 0x00000000 Exec Addr: 0x00000000 Partition Start: 0x000065D0 Partition Attr: 0x00000020 Partition Checksum Offset: 0x00000000 Section Count: 0x00000001 Checksum: 0xFFE776BE Bitstream In FsblHookBeforeBitstreamDload function PCAP:StatusReg 0x40000F30 PCAP:device ready PCAP:Clear done Level Shifter Value 0xA Devcfg Status register 0x40000A30 PCAP:Fabric is Initialized done PCAP register dump: PCAP CTRL 0xF8007000: 0x4C00E07F PCAP LOCK 0xF8007004: 0x0000001A PCAP CONFIG 0xF8007008: 0x00000508 PCAP ISR 0xF800700C: 0x5802000F PCAP IMR 0xF8007010: 0xFFFFFFFF PCAP STATUS 0xF8007014: 0x00000A30 PCAP DMA SRC ADDR 0xF8007018: 0xFC019741 PCAP DMA DEST ADDR 0xF800701C: 0xFFFFFFFF PCAP DMA SRC LEN 0xF8007020: 0x00080B00 PCAP DMA DEST LEN 0xF8007024: 0x00080B00 PCAP ROM SHADOW CTRL 0xF8007028: 0xFFFFFFFF PCAP MBOOT 0xF800702C: 0x0000C000 PCAP SW ID 0xF8007030: 0x00000000 PCAP UNLOCK 0xF8007034: 0x757BDF0D PCAP MCTRL 0xF8007080: 0x30800100 ...................................................................................................
