      @george Never mind. It just started working. No clue why, but I'll monitor it and let you know if it starts to get flaky.

      CST时间和UTC时间的区别,并不是不能同步。也不是RTC不工作。系统层的问题百度一下。

      @prcups 我现在也改用 6.1内核,目前用下来均正常。按需再定制内核。

      我会用docker构建跨平台的镜像,默认内核未开启 CONFIG_BINFMT_MISC,在使用中慢慢弄,也是很好学习的过程。 😊

      @george It's fine for me—as a TrustZone developer, I always use a custom U-Boot and build the entire system myself.

      However, it's good to keep this as a note to inform other developers.😊

      @zhengbicheng said in 获取推理结果坐标:

      第一种:针对RKNN推理精度问题,rknn-toolkit提供了连板调试的方法,但是我们还未开放这个方法。

      这个功能会开放吗,是硬件的更改吗?

      @王猛龙 目前没有做deepin的适配,原理上是可以支持的,内存卡理论没有容量限制,只和文件系统相关。

      @george ok so i just figured something out. I removed my power supply hat that i have on my pi so i could connect my serial terminal pins and get you a log, and behold the suspend function works when i powered it on with the usb c port. so seems that for some reason supplying power through the gpio pins for some reason wont let me use the suspend function.
