Use SD card or emmc for XU4 just for boot up ?

Unread postby atarioldskool » Tue May 15, 2018 3:46 am

Hi

I’m just about to place my order for odroid xu4 but can’t make my mind up on what type of memory to use just for the boot up
16GB sc card or a 16GB EMMC ?
I will be using a 2.5 SATA 1TB HDD for main storage emulator etc but don’t know what to get for the boot up side of things.
I know emmc is a lot faster at reading and writing,
I will be having dual boot android for the tv side terrarium, Showbox etc and Linux (can’t remeber the os name) for retropie or recalbox
Any quick advise will be much appreciated

For Android eMMC is almost a necessity in my opinion, for Linux a UHS capable SD is fine.

16GB Micro-SD UHS-1 card should be fine for Retropie/Recalbox gaming application.
Our official SD card is based on MLC NAND technology, it will give you reasonably fast response.

Or, Samsung EVO-plus should be a good choice since many users reported with very positive reputation.

But, if you use Android seriously, heavily consider buying an eMMC.

Back again on this topic.

My emmc is now flashed with retropie from odroid arena
I now want to complete the next stage which is to have my 2.5 SATA 1TB HDD AS THE MAIN STORAGE
SO ALL THE EMULATORS , roms, game progress is all saved onto the hdd and not on the emmc

Just want the emmc to just have the boot up skins etc.

Is it as simple as ETA YouTube link explaining it
https://youtu.be/P1etPYvWBZU

I know he was doing it on raspberry pi but I image it to be the same process ?

1 thing I’m unsure of is when he said as long as it is 32gb or less ? Well my hdd is 1TB

Thank you

I have no idea how ORA(ODROID Retro Arena) image handles the ROM files in an external USB storage.

I am attempting to use the same image but I am using a Sandisk 256gb micro sd card. It will boot but has major lag and crashes occasionally. But if I use a Sandisk 64gb micro sd card I have no problem. I format the SD card, then use Etcher to burn images. Can anyone help? Would like to get this 256gb card to work!

Did you flash this latest Ubuntu 18.04 image?

I know this probably sounds odd but I wasn't able to boot from my SD card until I attached an eMMC module into it. After the first boot, I removed the module and haven't had an issue with booting to the SD card since. I never had to move the SD/eMMC switch during the process. The system just wouldn't boot until I did that for some reason... PX
