T113主线u-boot支持代码：
https://github.com/willswang/u-boot/tree/t113-2022.10.y
Tested on mangopi-dual board with PE uart0
Support boot from spi-nand/mmc
Support heyangtek spi nand
Support usb/mmc/eth
Support env storage on mtd
Support boot mainline kernel
Build for mangopi-dual board:
make mangopi_dual_defconfig
make
Burn to spi nand:
xfel spinand write 0 u-boot-sunxi-with-spl.bin

内核是哪个版本？ mango pi 怎么接spi nand ？ 自己焊接吗 ？
mangopi-dual预留有spi flash焊盘，自己焊接一个就可以
主线内核6.0以上应该就都可以，只是支持外设驱动多少的问题
下面sun8i-t113.dtsi供大家参考：

starting kernel 卡住 内核设备树确认正常，能否开放一个内核测试版本
有启动log吗？注意console是PE uart0

内核改动不多，比较简单，所以没有专门放上去

u-boot用xfel写到spi-nand里面
kernel如果放在单独的分区，也是一样
或者把kernel放在ubi/ubifs里面，用u-boot烧写

设置工具链 export PATH=<绝对路径>/gcc-linaro-7.5.0-2019.12-rc1-x86_64_arm-linux-gnueabihf/bin/:$PATH，然后再用make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 编译

如果你需要做一些原厂无法覆盖到的差异化的东西，你就知道tina到底省不省心？
话说回来，除了turnkey和大厂，用全志的啥时候省心过，主要还是图便宜

最新的u-boot和kernel主线已经支持了T113，只不过里面的用的型号是R528
