同求

小猪佩奇 · 2018-07-04 15:43:24

主线好像不支持，需要加驱动

wind · 2018-07-05 09:34:35

全志的sunxi-tools不支持spi nand的烧写吧，你们是怎么把程序烧到flash里面的呢，不用烧片机

晕哥 · 2018-07-06 09:29:28

看了楼主的帖子,

正好立创商城这个月满 9.9 包邮, 乘机撸了两个 W25N01GVZEIG spi nand,

不知道啥时候能焊上去调通。

晕哥加油，要是2片不够的话我再给你支援几片 ~ ~

话说荔枝群里有位仁兄上传过spi nand flash从sunxitools到kernel的全套驱动支持，我没v3s的板子，你们有移植调试过木有呢

@晕哥
按照http://nano.lichee.pro/build_sys/build_flash.html里的参考编译出内核

给出的正常的打印信息会有

我自己使用主线4.15.0的内核,从spi-flash 启动出现
[    0.827100] SCSI Media Changer driver v0.25 
后不会出现上面信息，看样子不能正确识别到spiflash里的分区信息。
最终挂在Waiting for root device /dev/mtdblock3

烧录文件用官网，ko文件自己编译的?

[ 1.040519] Waiting for root device /dev/mtdblock3...

这个问题，
你先用ramfs这种根文件系统，
一定可以启动到shell，
然后手动mount mtdblock3
然后会出现非常明显的错误提示。

@晕哥，今天逛论坛，找到问题了，参考这个 https://whycan.cn/t_1180.html

是参考的18楼吗?

是的，18楼的

几乎熬了个通宵，终于找到原因了并解决问题了：官网下载的config文件，开错了全志的spi控制器开关，正确的配置是# CONFIG_SPI_SUN4I is not set
CONFIG_SPI_SUN6I=y(看来f1c100s用的是新版本的spi控制器)。修改后内核可以正确识别到spi flash了。另外，官网页面上还有个问题， uboot的bootargs 参数设置中， root=/dev/mtdblock3必须要修改为root=31：3，否则无法正确加载rootfs。修改以上两点后可以正确启动到控制台了。云盘中的sdk包4.13和docker中的4.15版本均是如此修改。
