petalinux2018.3在uboot中动态加载bit文件出现的问题

zhubaojun

第一步修改platform-top.h文件如下：

#include <configs/platform-auto.h>

#define CONFIG_FPGA_ZYNQPL            

#define CONFIG_SYS_BOOTM_LEN 0xF000000

#define DFU_ALT_INFO_RAM \

        "dfu_ram_info=" \

    "setenv dfu_alt_info " \

        "bitstream_bit=system.bit\0"        \

        "bitstream=system.bit\0"        \

        "loadbit_addr=0x100000\0"        \

        "mmc_loadbit=echo Loading bitstream from SD/MMC/eMMC to RAM.. && " \

                "mmcinfo && " \

                "load mmc 0 ${loadbit_addr} ${bitstream} && " \

                "fpga loadb 0 ${loadbit_addr} ${filesize}\0" \

    "image.ub ram $netstart 0x1e00000\0" \

    "dfu_ram=run dfu_ram_info && dfu 0 ram 0\0" \

    "thor_ram=run dfu_ram_info && thordown 0 ram 0\0"
#define DFU_ALT_INFO_MMC \

    "dfu_mmc_info=" \

    "set dfu_alt_info " \

    "${kernel_image} fat 0 1\\\\;" \

    "dfu_mmc=run dfu_mmc_info && dfu 0 mmc 0\0" \

    "thor_mmc=run dfu_mmc_info && thordown 0 mmc 0\0"
/*Required for uartless designs */

#ifndef CONFIG_BAUDRATE

#define CONFIG_BAUDRATE 115200

#ifdef CONFIG_DEBUG_UART

#undef CONFIG_DEBUG_UART

#endif

#endif
/*Define CONFIG_ZYNQ_EEPROM here and its necessaries in u-boot menuconfig if you had EEPROM memory. */

#ifdef CONFIG_ZYNQ_EEPROM

#define CONFIG_SYS_I2C_EEPROM_ADDR_LEN     1

#define CONFIG_SYS_I2C_EEPROM_ADDR       0x54

#define CONFIG_SYS_EEPROM_PAGE_WRITE_BITS   4

#define CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS 5

#define CONFIG_SYS_EEPROM_SIZE         1024 /* Bytes */

#define CONFIG_SYS_I2C_MUX_ADDR        0x74

#define CONFIG_SYS_I2C_MUX_EEPROM_SEL     0x4

#endif
#define CONFIG_BOOTCOMMAND        "run mmc_loadbit; run default_bootcmd"&#8203;

第二步 重新编译

petalinux-build&#8203;

第三步生成BOOT.BIN

petalinux-package --boot --fsbl --u-boot --force

第四步 拷贝BOOT.BIN image.ub system.bit到sd卡&#8203;

问题是进入uboot时候用run mmc_loadbit提示：

error: "mmc_loadbit" not defined

为什么会出现未定义错误，，不是在platform-top.h中定义了吗？

mmc_loadbit=echo Loading bitstream from SD/MMC/eMMC to RAM.. && " \

                "mmcinfo && " \

                "load mmc 0 ${loadbit_addr} ${bitstream} && " \

                "fpga loadb 0 ${loadbit_addr} ${filesize}\0" \

请问是哪儿出现了错误？

在这里修改：project-spec/meta-plnx-generated/recipes-bsp/u-boot/configs/platform-auto.h         <       "mmc_loadbit=mmcinfo && fatload mmc ${sdbootdev}:1 0x10000000 system.bit && fpga loadb 0 0x10000000 ${filesize} \0" \         <       "default_bootcmd=run uenvboot;run mmc_loadbit; run cp_kernel2ram && bootm ${netstart}\0" \         ---         >       "default_bootcmd=run uenvboot; run cp_kernel2ram && bootm ${netstart}\0" \

拷贝platform-auto.h文件中的CONFIG_EXTRA_ENV_SETTINGS块到platform-top.h文件，在CONFIG_EXTRA_ENV_SETTINGS 添加你的mmc_loadbit
