Re: 全志V3s荔枝派Zero板子,我用TF启动系统,bootargs里面有分区信息,进入Linux我执行spi flash更新动作,出现权限错误

看来看去, 这一行感觉有问题, 我帮你搜搜

console=ttyS0,115200 panic=5 rootwait mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,6M(kernel)ro,-(rootfs) root=/dev/mmcblk0p2 earlyprintk rw

我知道了, 你把ro去掉试一试

console=ttyS0,115200 panic=5 rootwait mtdparts=spi32766.0:1M(uboot),64k(dtb),6M(kernel),-(rootfs) root=/dev/mmcblk0p2 earlyprintk rw

谢谢大神, 终于可以了,我把上面一行拷贝到  u-boot的sun8i.h,
重写编译烧写u-boot到tf卡,重启,可以擦写spi flash了。
