[已解决]SPI Burn Image 参考资料

本帖最后由 2272943826 于 2016-11-25 09:58 编辑

刚收到 Hi3516A demo board，让我自己去研究。 我是新手。
疑惑：
        1 烧写文件去 demo board,用的是 bootrom, spi flash 还是 nand flash?
        2 fastboot工具， by default是按照分区烧写，地址烧写还是boot 烧写？

非常感谢
多多关照新人


学习啦3个月，向隅而泣：
1 我用的是 spi flash   参考材料：Description of the Installation and Upgrade of the Hi3516A/Hi3516D SDK

Burn images to the SPI flash.
   In this section, a 16 MB SPI flash is used as an example.
1) Address space
        |      1M       |      3M       |     12M       |
        |---------------|---------------|---------------|
        |     boot      |     kernel    |     rootfs    |
        The following operations are performed based on the allocated address space. You can change the address space as required.
    2) Burn the U-boot.
        sf probe 0
        mw.b 82000000 ff 100000
        tftp 0x82000000 u-boot-hi3516a.bin
        sf probe 0
        sf erase 0 100000
        sf write 82000000 0 100000       
        reset   
¡¡  3) Burn the kernel.
                mw.b 82000000 ff 300000
                tftp 82000000 uImage_hi3516a
                sf probe 0
                sf erase 100000 300000
                sf write 82000000 100000 300000
¡¡  4) Burn the file system.
                mw.b 82000000 ff C00000
                tftp 0x82000000 rootfs_hi3516a_64k.jffs2
                sf probe 0
                sf erase 400000 C00000
                sf write 82000000 400000 C00000
     5) Set boot parameters.
                setenv bootargs 'mem=64M console=ttyAMA0,115200 root=/dev/mtdblock2 rootfstype=jffs2 mtdparts=hi_sfc:1M(boot),3M(kernel),12M(rootfs)'
                setenv bootcmd 'sf probe 0;sf read 0x82000000 0x100000 0x300000;bootm 0x82000000'
                sa

2 fastboot我是按照 分区 烧写的
参考文件： Hi3516A/Hi3516D U-boot Porting Development Guide
3.3.1 Burning the U-boot to the SPI Flash
Perform the following steps:
Step 1 Run the following commands in the HyperTerminal after the U-boot runs in the memory:
hisilicon# mw.b 0x82000000 ff 0x100000 /*Set the DDR value of all Fs.*/
hisilicon# tftp 0x82000000 u-boot-hi3516a.bin /*Download the U-boot to the
DDR.*/
hisilicon# sf probe 0 /*Detect and initialize the SPI
flash.*/
hisilicon# sf erase 0x0 0x100000 /*Erase 1 MB capacity of the SPI
flash.*/
hisilicon# sf write 0x82000000 0x0 0x100000 /*Write the U-boot from the DDR
to the SPI flash.*/
Step 2 Restart the system. The U-boot is burnt successfully.
