Hardware eMMC reader for HAC-EMMC

[losth1ghway]

I'm curious if anyone has had success with the above posted chinese versions, as Ignas is currently out of stock on his tindie page.

I'm also wondering what the success rate has been like for people here. How often was the eMMC corrupted vs fully recoverable etc.

@JBDZ - Can I ask where you found out about these, and what software they run please?

I see it's using an RPi 2040 chip, so I'm guessing it runs some sort of PIO code? Have you used them? Do they definitely read the boot partitions?

@JBDZ is the developer from this nice stuff.
Work's Great can confirm.

Thanks - is there any documentation/info please? I've looked at the sales links, but that's all in Chinese (and Google translate doesn't seem to do well with it).

How does it work? What software do you need etc?

Sorry forgot to answer.
There is no advanced documentation.
It's simply a card reader that is able to read the bootpartions on emmc chips.
You need Linux and this tool and then you can mount the emmc partions.
It's similar to mmcblkNX GitHub documentation.

Thanks - I saw the one on Github, but that's based on an RTL chip + the rtsx driver.

In the photos of the one from @JBDZ it looks like it's based on an RPi 2040, so I just curious how it's working in Linux without any particular drivers?

Nope, it uses same RTS5170 like the GitHub original designed.

I guess I can kinda see the resemblance from the pics? But I don't blame him too much because the CSS/Superbuy listings both say "RP2040" in their titles lol

 

[evil_santa]

He is also active on twitter maybe someone could ask him there.

I guess those reseller sites are just doing eye catching title, and literally they have no idea what the item does.
I got mine from "Yellow-fish"(nick name） Chinese market place from the @JBDZ store, I dont see any rp2040 mentioned inside out.

I assumed the same thing, I've never ordered from any Chinese markets besides AE so I went with CSS since it had the most English lol

Has anyone purchased the clamshell emmc reader from @JBDZ ? looks interesting but also shows out of stock on taobao.

 

[JBDZ]

When the time is right, I will send out my RP2040, which will be unique.

@JBDZ - can you help with this please?

The latest mmcblk V5 has added a power switch,3.3V and 1.8V regulated power switch. Currently, it can support all EMMCs. For the time being, it can only work under ubantu system, dumping data information and BOOT0 and BOOT1 information by command. You can use the following tutorials. https://www.bilibili.com/video/BV1fS4y1B7Cy/

Thanks - there seems to be another related product on GitHub project ignasurba/mmcblkNX

I was confused (as someone else said), because RP2040 was listed in the title for your listings. And, as it happens, the RP2040 with its PIO would indeed be capable of doing this. I'm still not allowed to link things for some reason, but google "pi pico sdio", and the first result is "Pico w/4-bit SDIO interface example?", with people answering with lots of options.

I might have to make my own remix of the board because I just want CMD/CLK/DAT broken out as headers, so I can try dumping the eMMC on a board (nothing to do with Switch).

I used the ft232h to dump a fire TV 4k max.
This can dump a emmc in circuit including Boot0/1
Keep in mind direct partion editing is not possible. You need the exploitee low level adapter for this.

Thanks for idea, sounds interesting.

However, I don't think it helps in my situation:

1. The FT232H seems to be just a way of having GPIO/SPI etc directly from a computer, rather than using something like an SBC/Pi.
2. It's not clear what software's being used in the video you linked. "Postal3" yields no Google results - and what's with the photo in it?!
3. The PCB I'm wanting to read the eMMC from runs it at 1.8V, so I need some level shifting anyway.
4. I don't think the Exploiteer adapter will necessarily give me access to boot partitions - it then depends on the SD card reader you use. And the only ones that do are generally in old laptops and use the RLT5170 anyway.

 

[JBDZ]

ft232h can be dumped only at a low speed and is not suitable for swtich

I bought this at CCSBuy... of the two options, the most expensive... would you know how to tell me that it will reach me.
Thank you

Yes, as long as you operate normally, it will be delivered to you.
