奇怪了,我这里 D1 SPI NAND fastboot 直接失败, 啥也动不了。

Reply: 请问T113S3到底有没有CAN总线?有的话,是那些引脚?
驱动也没有,洗洗睡吧:
$ grep "allwinner," -r /opt/t113/tina/kernel/linux-5.4/drivers/ |grep "can" $

T113 Datasheet: T113-S3_Datasheet_V1.2.pdf
T113 SDK下载:
链接:https://pan.baidu.com/s/1AqFkZT5IRAvAA2wvgEYybA?pwd=awol
提取码:awol解压后只有一个 .repo 文件夹,需要用 repo sync -l 命令从本地仓库恢复文件。
T133和 R528 都是双核A7,内置DDR3 128M,只是封装有点差异。
手册上面确实只看到了功能,并没有引脚。

Reply: Tina如何打包SPI NOR、SPI NAND固件
TINA SDK 默认打包的就是 SPI NAND 固件, 也可以用于TF卡, 但是 SPI NOR 得单独改一个出来才行.
