Zynq 7010 uboot下tftp更新uImage及.bit文件

1、更新7z010.bit:[mw_shl_code=applescript,true]zynq-uboot> set ipaddr  192.168.1.72
zynq-uboot> set serverip  192.168.1.121
zynq-uboot> tftp 0x200000 7z010.bit[/mw_shl_code]

TFTP from server 192.168.1.121; our IP address is 192.168.1.72

  part number = "7z010clg400"

  time = "16:24:57"
  bytes in bitstream = 2083740
zynq_load: Align buffer at 20006f to 200000(swap 1)


[mw_shl_code=applescript,true]zynq-uboot> set sdboot 'if mmcinfo; then run uenvboot;echo Copying Linux from SD to RAM... && mmcinfo && fatload mmc 0 ${kernel_load_address} ${kernel_image} && fatload mmc 0 ${devicetree_load_address} ${devicetree_image} && bootm ${kernel_load_address} - ${devicetree_load_address}; fi'
zynq-uboot> boot[/mw_shl_code]


2、更新uImage:

[mw_shl_code=applescript,true]zynq-uboot> set ipaddr 192.168.1.72
zynq-uboot> set serverip 192.168.1.121
zynq-uboot> tftp ${kernel_load_address} uImage[/mw_shl_code]
Gem.e000b000 Waiting for PHY auto negotiation to complete..... done
Using Gem.e000b000 device
TFTP from server 192.168.1.121; our IP address is 192.168.1.72
Filename 'uImage'.
Load address: 0x2080000

done
Bytes transferred = 3627368 (375968 hex)
[mw_shl_code=applescript,true]zynq-uboot> set sdboot 'if mmcinfo; then run uenvboot;echo Copying Linux from SD to RAM... && mmcinfo && fatload mmc 0 ${devicetree_load_address} ${devicetree_image} && bootm ${kernel_load_address} - ${devicetree_load_address}; fi'
zynq-uboot> boot[/mw_shl_code]

我按照上面的方法，试验。但是失败了。我用关盘里面的boot。bin作为启动文件从qspi flash里面启动。按照上面的方法，输入 zynq-uboot> set sdboot 'if mmcinfo; then run uenvboot;echo Copying Linux from SD to RAM... && mmcinfo && fatload mmc 0 ${kernel_load_address} ${kernel_image} && fatload mmc 0 ${devicetree_load_address} ${devicetree_image} && bootm ${kernel_load_address} - ${devicetree_load_address}; fi' 后，开始boot，结果如下：

以上的例子是基于SD卡启动的，环境变量也是，看那个sdboot就知道了
