- 最近再研究远程升级的问题,都做完了,确实是欠考虑了,如果程序升级过程中死掉了或者因为其他原因导致重启之后跑不了的话,程序无法回滚。。。
- 再有就是我使用FSBL生成的引导程序,BOOT.bin文件=FSBL.elf+程序.elf+FPGA.bit。
- 考虑到之前学过BootLoader,那么就需要把BOOT.bin拆成Bootloader和APP程序(FPGA.bit+程序.elf)。也就是说要自己写引导程序。
- FLASH型号:W25Q128,128Mb=16MB,分析了之前的BOOT.bin存在的地址是从0x0000_0000开始的。
分析一下zynq启动过程:
Device Boot Flowchart
PS部分
重新上电复位:复位所有寄存器硬件采样mode引脚;JTAG/IOP/DDR等控制器失能;根据使用标头加密参数的BootROM确定安全Boot模式;PLL通过。
非重新上电复位:保持之前的Boot模式,使用devcfg.CTRL[SEC_EN]寄存器位供BootROM访问;复位除了保持的寄存器之外的寄存器;安全、非安全模式。
阶段0:BootROM 执行
阶段1:FSBL(引导加载程序)或用户代码
阶段2:操作系统
PL部分
PL硬件包含一个用来准备初始化的自启动序列。后续就是进行初始化,配置,使能。

参考我自己写的思路:
规划分区:
//Every 32KB find BOOTROM valid headerxil_printf("---------- Enter BootLoader----------\n");xil_printf(" BOOTLOADER VERSION: %s.%s\n",MAJOR_BOOT_VERSION,MINOR_BOOT_VERSION);xil_printf("======== flash pration table ========\n");xil_printf("| name | offset | size |\n");xil_printf("-------------------------------------\n");xil_printf("| boot | 0x00000000 | 0x00100000|\n");//32KB*32=1024KB=1MBxil_printf("| app | 0x00100000 | 0x00600000|\n");//32KB*32*6=6MBxil_printf("| download | 0x00700000 | 0x00600000|\n");//32KB*32*6=6MBxil_printf("| setting | 0x00D00000 | 0x00300000|\n");//32KB*32*3=3MBxil_printf("=====================================\n");
调试的时候,可以在FSBL工程/src/fsbl_debug.h添加宏定义,可以看到启动过程中的调试信息。
#define FSBL_DEBUG_INFO
控制程序重启:
#define PSS_RST_CTRL_REG 0xF8000200 //PSS_RST_CTRL寄存器,绝对地址,
#define SLCR_UNLOCK_ADDR 0xF8000008 //SLCR_UNLOCK寄存器,绝对地址,
#define UNLOCK_KEY 0xDF0D //使能码
#define PSS_RST_MASK 0x01 //复位码void PsSoftwareReset(void)
{Xil_Out32(SLCR_UNLOCK_ADDR, UNLOCK_KEY); //写使能Xil_Out32(PSS_RST_CTRL_REG, PSS_RST_MASK); //复位
}

ZYNQ软件复位重启、程序跳转的实现方法(Multiboot)_zynq multiboot-CSDN博客
控制程序跳转:
#define XDCFG_MULTIBOOT_ADDR_OFFSET_REG 0xF800702C //MULTIBOOT寄存器,绝对地址,
#define XDCFG_UNLOCK_OFFSET_ADDR 0xF8007034 //XDCFG_UNLOCK_寄存器,绝对地址,
#define UNLOCK_XDCFG_KEY 0x757BDF0D //使能码#define APP1_LOCATION 0x00 //APP1位置
#define APP2_LOCATION 0x08 //APP2位置,以32KB为单位,8*0x8000=0x400000void ModifyMultiBoot(void)
{Xil_Out32(XDCFG_UNLOCK_OFFSET_ADDR , UNLOCK_XDCFG_KEY ); //写使能Xil_Out32(XDCFG_MULTIBOOT_ADDR_OFFSET_REG , APP2_LOCATION ); //更改MULTIBOOT
}
MultiBoot
zynq是按照每32KB搜索有效启动头。

学到了一个东西,这个地方可以调整,可以把文件烧到不同的地方。
程序框架搭完了,网络连接不上,还没找到原因,原来的程序就行,新建的程序不行,使用的还是同一个bsp。
后来通过一点一点注释代码,发现不能在while(1)里面加usleep,会导致网络连不上。

早上测试烧录正常,但是不能从BootLoader切换到download区。找到问题原因,修改程序:
Xil_Out32(XDCFG_MULTIBOOT_ADDR_OFFSET_REG , DOWNLOAD_LOCATION ); //更改MULTIBOOT
#define DOWNLOAD_LOCATION 0x12这个DOWNLOAD_LOCATION 以32KB为单位,0x12*0x8000=0x00100000
升级完成,成功切换了!!!

然后就是要考虑在Setting区域,给boot_state、download_state、app_state、ip等信息置位。尝试了直接写,读出来值不对,查了好多资料,也没说到底怎做。
后来对比了正点原子和其他例程,开始怀疑是不是W25Q128有什么说法。
2024.06.03:
搜索了一下W25Q128说是要先擦除,再写入。
每次你要先从FLASH读出来,存在数组里,修改某个字节之后,先擦除,再写到FLASH里。还有FLASH没写过的时候全是1,只能从1变成0,不能让0变成1。如果想让0变成1,就要全部刷掉然后再写。
测试写入IP地址,确实没问题。
考虑到感觉没有必要写回滚。规划分区APP那一分区暂时不用。
从BootLoader下载APP(download区),到APP(download区)运行;从APP(download区)回到BootLoader下载新的APP(download区),再到新APP(download区)运行。运行了一圈没问题。
