分享T113 can驱动,支持T113-S3/T113-S4芯片发布在 D1系列-RISC-V

回复: 通过USB共享使D1s上的tina联网(RNDIS Gadget)发布在 D1系列-RISC-V
@maihuanyi 这个我这边测试t113也是这个问题，ping可以通，使用ssh连接内核崩溃，后面我换了ncm方式，就没有这个问题了。

回复: D1s 无法从EMMC启动发布在 D1系列-RISC-V
@whycanservice partitions=boot-resource@mmcblk0p1:env@mmcblk0p2:env-redund@mmcblk0p3:boot@mmcblk0p4:rootfs@mmcblk0p5:private@mmcblk0p6:UDISK@mmcblk0p7 这个分区传参不是显示是 mmcblk0p5
