I think I've saw something about it (and how to do) in a BoundaryDevices(.com) page ... but I can't find the link right now.

I think they have written a tool to write on the eMMC/flash from Linux but I don't know if it will work on Matrix ...

It's worth a try, esp if it's open source. I'll look tonight.

Wine doesn't have access to low level USB interactions, qemu doesn't support USB hot plug. Virtual box kernel modules won't compile on 3.13

So I'm stuck

Actually I don't know (didn't try ) hoy you can access the flash in boot mode under linux. But the relevant files and procedures from log:

booting into flash mode (but don't know how):

Code: Select All Code

At this stage it changes the device to block device so you may write the flash...

Here it looks like it writes raw the uImage kernel on the begin of the mmcblk0 with 1M offset, which is behind the boot part of the u-boot, then in makes the FS... this looks like that:

Code: Select All Code

#!/bin/sh

# partition size in MB
BOOT_ROM_SIZE=10


# call sfdisk to create partition table
# destroy the partition table
node=$1
dd if=/dev/zero of=${node} bs=1024 count=1

sfdisk --force -uM ${node} << EOF
${BOOT_ROM_SIZE},,83
EOF


and than you just untar the rootfs on it...

but all is more or les guessing...

I'm very interested in how to flash the matrix from a linux host as well. I've done some searching and I found this thread: https://community.freescale.com/thread/284170
It doesn't look good...
I'd love the hear if anyone else has made any headway on this.

I gave up, wasnt worth the time.

I now flash by booting to an SD card then writing the eMMC from there. or just boot by tftp, its super fast if your going to be making alot of changes.
