I also used some other cards for testing, sandisk or samsung... the results are the same.
Between a success boot and a failure boot, I 've never touched the SD card, I just plug and unplug power adapter from power outlet.
Control variable and exclusion, still no pattern was found. I know the the troubleshooting process is boring, but it's meaningful. Your Amlogic S9xx kernel helped hundreds of thousands of people in China turn their TV boxes (Phicomm N1) from trash to wonderful gadgets.
Yeah, great, it worked. From the storage space of the root, I can confirm that boot comes from USB drive. So far, every attempt of booting from the USB drive was successful. So, that's a problem of SD card.
I observed that desktop response is slower than 4.19 kernel, and some minor issues. But it's okay, I understand that the edge kernel is not ready yet. You're genius.
BTW, be careful when you insert SDCard into the slot. It is better not to use a screwdriver
I just found that this is a SIM/MicroSD 2 in 1 slot, and SIM card should be inserted upside down.
Fixed LAN2.
Fixed the reboot and shutdown of the Sd card.
Added support for the on/off button. Now, after switching off, you do not need to pull the power supply out of the mains, just press the button on the P2 case. Also, the operating system turns off when the button is pressed briefly.
Both media (SD + USB flash drive) must be connected to the device together.
the reboot does not work, only a complete power off.
