So here's a couple of µSD card readers that I've tried:

Working
Sabrent CR-UMSS - this one worked fine, however it broke unexpectedly after 2 or 3 uses. The stick looks cool, but the build quality (and price) aren't that great. Avoid.
Ωmega Card Reader - a generic no-name brand reader; works perfectly with the Hardkernel µSD adapter. Very cheap, but does the trick.


Not working
Sony Ericsson CCR-80 - Came with a Sony Xperia phone I own, so naturally I tried it. Works with plain old µSD cards, but doesn't recognize the Hardkernel adapter. Avoid.

Hello,

I have a no-name card reader and it is working quite fine, I have just flashed one disk image with it:

We've developed a fast and reliable USB 3.0 eMMC Writer with the following specification.
- USB 3.0 Interface
- Native eMMC 8bit wide data interface, instead of slow SD 4bit width
- Works in HS200 mode
- Flashing speed is 3-4 times faster than a normal USB 3.0 card reader i.e. Transcend TS-RDF5K.
- Windows / Mac / Linux Compatible
- Works with ODROID Orange, Red and Blue eMMC modules (It is not compatible with the Black eMMC Modules)
- Use with Etcher or Win32DiskImager software on your PC
- It can't access the eMMC hidden boot blocks, unfortunately.
- Rated Power : 5V/500mA (including eMMC module)
- Dimensions : 60x26x4.5 mm

I am not certain what the point of the Odroid branded reader is if it can't read the boot blocks. Do any of the others work (for example, the Transcend ones shown at the top) for reading/writing the boot blocks?

For that matter, how would I actually write those (if the reader allows it) when flashing the card? Wouldn't the image just put the boot section in the normal memory, not the hidden portions? (A rather large concern for me: and, for readers like the official Odroid one or others that don't show the hidden areas, what does flashing an image do if it CAN'T find the hidden partitions?)

There's got to be a way that doesn't involve an SD card and an Android image, right? That option still seems sketchy.
If I can't open it, I don't own it.

AFAIK, there is no card reader/writer can access the hidden boot block from a host PC via USB mass storage interface.

Once you boot from SD card, you can access the eMMC hidden block via /dev/mmcblk0boot node.
Refer this wiki page.

So there's some magic thing that the board can do with the eMMC that no card reader can?
But at least the board can... somehow.

Quick question: The fastboot options: Are those run from the Odroid, or do I somehow connect it to another computer and run it from there?
If I can't open it, I don't own it.

The fastboot protocol needs the micro-USB device port while XU4 has no such interface. XU3 has a micro-USB port works in device mode for fastboot interface, not a host mode.
But you still need a bootable device(SD or eMMC) even on the XU3 to start the fastboot communication.

There is no magic. XU4 Exynos SoC must load the boot binary from the hidden boot block in eMMC if you don't use an SD card.
We can't change the SoC internal ROM code.

Anyway, it is too much off-topic. Open a new thread if you need further discussion.

I just received this order and I see that this adapter doesn't support "black eMMC" modules.
This is pretty disappointing.
Why doesn't it work?

That is a good question. For that matter, why is the Orange the only one still produced? Isn't 5.0 a step back from 5.1?

Orange eMMC module has the eMMC 5.1 chipset.
The eMMC Writer board was designed with our eMMC PCB rev 0.4(Orange) while the black eMMC PCB revision was 0.3.

So, I just bought an XU4 and a 16gb eMMC from hardkernel, and also the eMMC to microsd adapter. I went to Best buy and got a microsd to us adapter, but it can't see the eMMC chip at all. I don't think it's compatible. However, from what I read above, can't I just buy an SD card, boot from that, then use the odroid itself to flash the eMMC to what I want? That's the only way to change the hidden sectors anyway right? Do you have to change the hidden sectors to for example put Lakka on it? If I did buy a microsd to usb adapter that did actually work, it still couldn't change the hidden boot sector of the eMMC right? So what's the point? Wouldn't that do nothing at all then? I don't understand. Do you have to change the hidden sectors to change the OS on the eMMC or not?

So either I got unlucky with my particular device or they change something in this particular model
I am also suspecting my emmc is bad, not sure if this would change things.
But my generic Chinese reade detects it without problems.

When you said it didn't work what do you mean? It won't see the eMMC or won't boot after written to?

I would return the Transcend and get another, they are actually the recommended SD reader and a lot of people use them here on the forum.

Does it look like this?

IT doesn't say 'USB 3.0'
The box says 'USB 3.1 Gen 1'
Just like the one I showed in the Amazon link https://www.amazon.com/-/es/Transcend-T ... 009D79VH4/

So I guess they changed something in this version
Do you have an Amazon link to the reader you have? PErhaps this one: https://www.amazon.com/-/es/Transcend-T ... 00PNQ9XIG/ ?

According to my purchase history it's this one:

https://www.amazon.com/dp/B009D79VH4

I think it's a new revision as you said, you may want to get a different one.

@odroid It seems like the updated Transcend RDF5K (USB 3.1) has a compatibility issue writing to eMMC, may want to mention it on the wiki or somewhere.

We need to buy one of the new batches for testing.

Can you show us pictures of your card reader? Front and rear side pictures will be useful to find the same product in Korea.

It's definitely a new revision.

Personally I would return it under the pretense it's not what you ordered, I hate when companies pull this. They do this a lot with routers, v1 will have more flash and RAM but v2 will be crippled and built purely to save money and incompatible with the previous model.

I have a Linksys device that changed to an entirely different SoC from v1 to v2, it went from a 1.4ghz Qualcomm to an 880mhz Mediatek.

Does it get very hot when you plug the reader in?

Not particularly. But it seems a bad emmC card.
Still, with a chinese generic reader I can detect it.

Try flashing an OS image with the Chinese generic reader with Etcher program.

BTW, the black eMMC module is not compatible with the Exynos platforms such XU/XU3/XU4/U2/U3/X/X2 boards.

I was not able to
I describe all my problems with that card here: viewtopic.php?f=137&t=38828

So let me understand right. There is a specific type of emmc card for each platform (or set of platforms) and for each OS ?

The emmc I show in the picture is black, right? Wouldn't the warning in the link you gave me apply?

'Listed all kind of eMMC are NOT compatible with USB3.0 to eMMC Reader.'

Right, the black emmc is not compatible with the usb-emmc adapter, but is with the emmc to microsd adapter.
