Hello, currently im running the above mentioned box with S905X and 1 GB of RAM on the 9.2.8 build, which was working fine till i needed some unsupported Python 3 Updates.
Im trying to get the new build to work, but after the box does some loading and rebooting, i see the coreelec logo and after that only black screen. i tried 2 usb sticks and sd cards already. nothing works.
im trying to run exactly this, with the device tree. it does not work for me…
The legacy build on internal emmc is running good. What is going on here?
Two things. First: you can’t upgrade CE from Leia to Matrix installed on emmc. You have to install Android prior and then run ceemmc -x to install CE in emmc. If you have the 8gig ROM Version, you might better off running CE from SD card. Second: you have to upgrade your bootloader to at least 7.1.x in order to run Matrix.
The class of the SD card doesn’t make that big of a difference from a speed/user experience perspective. You want a card with a high random r/w speed when an OS is on it. I suggest testing your cards with crystal disk mark, and use the one with the highest random speeds. It can make a huge difference depending on what speeds you are coming from/going to.
Here are a few card test results that were done on Raspberry PIs, but every batch of cards (even the same model) will have variance. https://www.pidramble.com/wiki/benchmarks/microsd-cards
Using a Class 10 SD Card is a minimum requirement.
To run CoreELEC on the A95X-B7N, I use a Sandisk Cruzer Fit USB 2.0 Flash Drive. While any USB Flash Drive will do, I prefer the Cruzer Fit because of it’s small physical size. I find the performance aduquate.
USB 2.0 Flash Drives offers transfer rates upto 480 Mbps whereas class 10 SD Cards max out at 10 Mbps, while the eMMC module of the device reaches about 50 Mbps (which is comparable to a V60 SD Card).
If you want to go for a new device, I’d suggest at minium SoC S905X3 or S922X.
