Orange Pi One and Orange Pi PC: stalls at boot with Armbian_5.91_Orangepipc_Debian_buster_next_4.19.59

Recommended Posts

I have several Orange Pi One and Orange Pi PC boards (the original ones, H3-based). I have downloaded the latest Armbian release for them Armbian_5.91_Orangepipc_Debian_buster_next_4.19.59 and imaged several SD cards in Linux with dd. The cards are all class 10, some are Sandisk and some are Samsung. I am using a 2.5A power supply for the boards.

 

For all the boards and all the SD cards I get the same result. U-boot starts, gets to the point of loading the kernel, clears the screen then displays "Loading, please wait" then "Starting version 241" and stalls there. Nothing else happens no matter how long I wait. If I power the board off and then back on, the same thing happens.

 

This happens with 3 different boards (one Orange Pi One and 2 Orange Pi PCs), and 5 different SD cards. The SD cards are all 16GB, class 10, 3 are Sandisk and 2 are Samsung. Any combination of board+card gives me the same result.

 

The way the cards are written is with:

dd if=Armbian_5.91_Orangepipc_Debian_buster_next_4.19.59.img of=/dev/mmcblk0 bs=4M

I have used the same approach with Armbian for the Odroid-C2 with the corresponding version of Armbian, and that worked well.

 

If I connect any of the boards to the Linux PC via USB-TTL adapter and use a serial console, the boards freeze before loading the kernel. Here is the serial console output.

Huh, I became suspicious that it may be a power problem when the kernel wouldn't load correctly with the serial monitor attached, so I changed the power supply from a 2.5A one to a 5A one, and now all boards boot correctly. Please ignore the above.

 

I didn't realize that these boards were quite so power hungry. It's funny because the CPU doesn't get even slightly warm while doing an update. I wonder where all that power is going.

No they are not power hungry ;)

I got more than 5 boards on a USB-Multiloader. The One & PC are running very cool.
Maybe you also changed the USB-Cable against a better one? :)

I'm not using any USB cables for power. I use dedicated power supplies with barrel connectors. With a 2.5A power supply, the boards don't run. With a 5A supply, they do. But I agree they're running cool. So maybe my 2.5A power supply is faulty.

I use the USB-A to Barrel cable for my OPi's - maybe it was a connector problem?

Don't think so, the connectors are snug on both power supplies, and the boards do start uboot but stall when the kernel kicks in. Maybe there's a momentary power demand increase that the smaller PS can't cope with and it stalls the kernel.

A practical and easy-to-use solution would be grabbing an usb voltage tester. Ideally you plug it into the USB connector of your board to get an idea about the voltage drop across the SBC which is in my eyes more interesting than how much amps the board takes. A multimeter will do it as well of course ;)
