I’ve had two older AML-S905X-CC boards that I’ve used for a while, have used them a lot lately and like them. These were using SanDisk 32GB A1 SD cards. Worked well. Here recently I bought 5 more AML-S905X-CC boards with heatsinks and USB wifi. I’m having problems with these new boards.
The new boards have colored GPIO headers, that’s a nice addition. With the new boards, I’m using 5 new SanDisk “ExtremePro” 256GB A2 SD cards. I’m coming to the forums here because I think the odds of multiple of these all having the same issues is slim.
I’m using this image for the new boards:
First board that I powered up, I updated the OS and started installing various packages. I was getting “read only” errors from the OS periodically. When this happens, the OS is no longer able to read the SD card at all. For example, I couldn’t use commands like “clear” or “vim”, it would say command not found. I would power off/on and the issue would go away for 5 or 10 minutes, but would come back. I have tried re-seating the SD card while it was off, but still the issue would come back. Eventually re-wrote the image to the SD Card and that one is acting OK now.
Second board, the issues are similar but worse. Periodically, the board will give the same problems, being unable to read/write to the other new SD Card. And upon rebooting, it would no longer boot. So, I re-wrote the image to this SD Card. After re-writing the SD card, when the board powers up it just gives me a GRUB command line.
I have the GPIO jumper moved to the outter pins so I can use the GPIO header on all the boards. I have pins 6, 8, and 10 hooked up to a sound isolation board called “EASY DIGI”.
I have many of these sound isolation boards, they work fine with my older AML-S905X-CC boards and the Raspberry Pi3 fine, I’ve not had any issues like I’ve described here in the past. I also have cm108 based USB sound cards connected to the boards, and the provided USB wifi as well.
I’ve not powered up or used the other three boards yet, trying to figure out what’s going on here. I’m proficient with Linux but this is a bit beyond me. Any help would be appreciated.
