=> BootLoader 模式下无法刷板子 只能在MaskRom模式下刷固件 请尝试在切换emmc存储步骤前，把spi flash擦除
使用附件loader，记得解压
使用最新ubuntu固件https://www.t-firefly.com/doc/download/106.html
参考https://wiki.t-firefly.com/zh_CN/ROC-RK3566-PC/03-upgrade_firmware_with_flash.html
先进入maskrom模式，高级功能，下载loader
然后读取存储列表，切换到spinor，擦除所有
再切换到emmc，擦除所有
最后回到升级固件页面，升级固件
已完成，主要是spinor没擦除 {:4_211:}
