That's it.

Pick a release -
ixtab didn't mention which one he based his build on - but go by the date of his post - probably something that was recent on that date.

Or
Pick a more recent release, closer to the device you want to work with.

Or
Just use his already built binary attached to the post you linked to.
Why do you want to repeat the work he already did?

I must compile a version of uboot that sets S/N and board id for me. So binary is no go.
EDIT: hint here https://www.mobileread.com/forums/sho...&postcount=679
I'm not sure I have to do this though.
Can I connect to the uboot command line to have access to the `idme` command with the device in this state?

The u-boot is talking over the serial port, same as the SoC before it and the kernel after it.
So yes, but it my only be available in the full u-boot build.
What you see at first is a mini-uboot, you have to load the full one manually (called: bist).

The 'idme' command is also available over a fastboot connection, but you have to use the kindle's serial port to start fastboot.

Both ways of accessing the idme command require only u-boot to be working, the rest of the eMMC can even be erased.

Read the thread about recovering a Kindle with fastboot, that one was an 'erase all' victim.

How do I get to fastboot mode?
All I found in the forum is getting earlier devices into that mode with their magic keys.

At the u-boot prompt> bist
Then at the bist prompt> fastboot
or combine the two:
u-boot> bist fastboot

The device doesn't get there, its board id and s/n are erased.

Try i.mx_loader, its around here somewhere.

RoBoKoP · 02-09-2016, 04:10 PM

I have the serial console, the kindle outputs this:

Code:

NNt 2009.08-lab126 (Sep 06 2012 - 16:07:56)

Now I cd to imx_usb's folder:

Code:

# ./imx_usb fastboot.bin
parse mx50_usb_work.conf

loading binary file(fastboot.bin) to f8006000, skip=0, fsize=800 type=aa

<<<2048, 2048 bytes>>>
jumping to 0xf8006400

loading binary file(fastboot.bin) to f8006000, skip=0, fsize=120bc type=aa

<<<73916, 73916 bytes>>>
jumping to 0xf800642c

Up till here there's no output on the serial console.

Now I cd to the NiLuJe's Fastboot-Kindle tool:

Code:

#./fastboot getvar serialno
< waiting for device >

What did I do wrong?

knc1 · 02-09-2016, 04:24 PM

I suppose you didn't use iMX_loader to write the board and serial number.

And that copy of fastboot doesn't have the tables required to start RAM.

"No dcd table"

NiLuJe · 02-09-2016, 04:31 PM

Wait, I have a fastboot tool in my name??!

Must have been confusing me with someone else

imx_loader doesn't have options to write those variables.

Where do I get my hands on it?

knc1 · 02-09-2016, 06:18 PM

That link you gave does not look like it has anything to due with this forum, its members, or even about Kindles.

Where you referred there by a thread or post on this site?

Since your trying to recover a Kindle, I suggest you stay with the things posted here.

Note: At the link you gave, read the bottom paragraph of the 'usage' message.

We (I) have posted all of the i.MX6 reference materials here, somewhere.
Those will give you an idea of what your looking for here.

I honestly don't recall where any of those things are (but then, I don't ever push: "erase all").

RoBoKoP · 02-09-2016, 06:35 PM

Yeah that was the wrong github link, the correct is this:
https://github.com/aditya3098/imx_usb_loader
which a fork of the former.

I tried this uboot: https://www.mobileread.com/forums/sho...&postcount=728
imx_load says "No dcd table" for it as well.

RoBoKoP · 02-10-2016, 02:05 AM

I managed to compile a custom uboot that sets a board id from Amazon's sources.
Trying to upload that with imx_usb does nothing just like the other *.bins

I rebooted into windows so I can use MfgTool hoping that it would work, but windows 10 is not supported.

Rebooted into OS X to try this procedure but imx_usb fails.

Ideas welcome.
