News about ODROID eMMC Modules

Post by odroid »

Today, we will tell you two news related to our eMMC modules.

This is the first news.
The price of NAND Flash components has been steadily decreasing over the past half year, and accordingly, our eMMC module prices have been significantly reduced.
Especially in the case of the 32GB model, it has been lowered by about 30%.

This is the second news.
We just started selling our new 256GB eMMC modules.
Although the form factor is smaller than a postage stamp, we hope you feel the peace of mind provided by the large capacity storage device.

The read and write speed is similar to that of the existing 64GB and 128GB products, and the iozone performance test results are as follows.
It was tested with ODROID-C4.

Good news on both fronts, lower price and a higher capacity option. Very nice.

Greetings,

I have a couple of questions about this device that I cannot find definitive answers to. One of them might have been answered just by visiting this forum. I've got an XU4 that I've been running ArchLinux on with a 64GB eMMC module Arch just doesn't seem to be updating anything though. Kernels are ancient. Thinking of making a switch. Wasn't sure what the eMMC capacity was on the XU4 but coming here I noticed the 256GB modules. Will it address all of that memory?

The other thing is Arch had an odd install procedure where you flash to a MicroSD card and then transferred it to the eMMC. Cumbersome time consuming and possibly error prone. Seems I've read that it's possible to flash directly to eMMC. I've soft-bricked this thing too many times; time for something more modern I think.

I've been a UNIX/Linux/Android developer as a profession for almost 24 years. No stranger to it on anything from the big iron servers to virtual machines down to embedded devices. I guess I just need to understand those things and probably some guidance when I go to buy another card. I've pulled down the 2 latest Ubuntu images. Going to try to find the kernel src here since that's the thing that's been driving me the most crazy with this thing.

Many thanks and Kind Regards!

Personally, I have not been using Arch Linux for over 7-8 years, so it is difficult to give an exact answer.

Which Kernel version have you used on your XU4?
We are supporting Kernel 6.1 at this moment even 256GB eMMC module could work with very old Kernel 4.4 certainly.

If you post your questions in the XU4 sub-forum, other Arch Linux experts will hopefully be able to help you.

Greetings,
Thanks for your thoughts and response. The Odroid-xu4 ArchLinux image ships with 4.14.180-3 yet their other devices and server/desktop will get you pretty close to bleeding edge. I've always loved Arch but when you need functionality your current kernel can't provide reliably, what do you do. I just built your 6.1.67 this morning and SURPRISE! All of my zswap/zpool problems/anomalies have vanished. (I'll be forking the tree and committing a patch for zswap since it really makes a difference on devices with limited memory. I may, yet I already have Arch running on 6.1 and my problems vanished. The jump from 4.14 to 6.1 was remarkably noticeable, especially when stuff starts working.... LOL

Many thanks and kind regards
