DFU needs a partition “table” to operate… Let’s create one as a temp, just to get things loaded…
First run on the Pico:
ums 0 mmc 0
Next, on your development machine: (replace DISK with /dev/sdX, look at lsblk and use the new driver that’s the pico…)
sudo dd if=/dev/zero of=${DISK} bs=1M count=10
sudo sfdisk ${DISK} <<-__EOF__
1M,,L,*
__EOF__
sudo mkfs.ext4 -L rootfs ${DISK}1
Now in u-boot kill the “ums 0 mmc 0” and rerun the “dfu 0 mmc 0”…
Regards,
Yes Sir,
Thank you for replying. @RobertCNelson: It worked like a charm.
Seth
P.S. You have been more than patient. I appreciate the support.
Okay sir, at the end of the instruction set, when you type out reset in the u-boot cli, what should I do w/ u-boot once it resets?
Seth
P.S. I am asking b/c the board disappears from the desktop and I pushed the button before three seconds was over when u-boot booted back in the u-boot cli. Please send guidance.
@silver2row, well if you followed the full directions after calling “reset” it should boot into linux. Please show what u-boot is dumping to the serial console.
Regards,
Sir,

P.S. This is what happens once I try to let u-boot’s reset option go past the three second mark. I will try again. Do I need tftpget and do I need to use /dev/ttyUSB1 instead?

This just means you need to go back and run (from U-Boot console):
ums 0 mmc 0
Then on your development desktop, mount the new usb drive that shows up and follow this section of the wiki…

Regards,
Sir,
Should I go through that section only or through that section and until the end of the instruction set?
Seth
P.S. I have tried just about everything. I am not questioning you b/c you do not know things about adding boards via CC and u-boot but I want to make sure I get it right this time. This way, if something arose b/c of my actions dedicated to the board configuration, I could post again to get better help.

At one point, I was thinking this was going to work w/out the Ethernet cable. I tried to plug in the Ethernet cable and as you can see, the same info. popped up.
…
Sir, do I need to umount or sync the device at all once I follow the instructions?
I still cannot sign in via ssh, too. Now, I have a rootfs system on my desktop even when my board is not plugged in. Does this make any sense to you?

You are getting closer, it looks like you didn’t correctly copy the kernel image/rootfs… From this section:
https://www.digikey.com/eewiki/display/linuxonarm/PICO-PI-IMX7#PICO-PI-IMX7-CopyKernelImage
Regards,
Sir,
When I am in USB Boot Mode, I receive this complaint: Header Tag is not an IMX imagee)�.
Does this mean anything?
Seth
P.S. I will attempt to try again.
You have no reason to go back to USB Boot Mode, at this point just leave it in eMMC Boot mode running “ums 0 mmc 0” and correctly copy the kernel files…
Regards,
Sir…Seth here. I am still trying here. Um, The u-boot cli is stuck on:
=> reset
resetting ...
…
I figured it is b/c of the dfu 0 mmc 0 command in u-boot. I tried to use it and then I went to my dev. desktop to put in the sudo dfu-util -D SPL -a spl command. I was unable to do so again. Now, when I listen to the instructions you gave me for,
sudo dd if=/dev/zero of=${DISK} bs=1M count=10
sudo sfdisk /dev/sdb <<-__EOF__
1M,,L,*
__EOF__
sudo mkfs.ext4 -L rootfs /dev/sdb1
I get an error.
Seth
P.S. The error is the same as above, i.e.
torx@forket:~/u-boot$ sudo dfu-util -D SPL -a spl

Right now, this is what u-boot console shows. While the cmd dfu 0 mmc 0 is typed and after I press enter, nothing.
It just makes me think that I need to use the cmd in the development desktop.
Seth
@silver2row, you only need to use run “dfu 0 mmc 0” once, it’s mostly about updating the ancient default bootloader (while in USB Boot Mode) to mainline U-Boot, so we can boot in eMMC Boot mode with a U-Boot that has a good version of “ums 0 mmc 0”…
At this point you have a good version of U-Boot in the eMMC, just mount the drive with “ums 0 mmc 0” and write the rootfs to the drive.
Regards,
Sir,
I am confused on this section: https://www.digikey.com/eewiki/display/linuxonarm/PICO-PI-IMX7#PICO-PI-IMX7-SetupmicroSDcard.
Where it states this cmd: export DISK=/dev/mmcblk0
Should I use /dev/sdb or /dev/sdb0?
Seth
P.S. I have more questions. I am fooled by that section b/c of errors I am coming across. Just for reference, I have tried under /dev /sdb, /sdb0, and /sdb1. All of which have given me errors.
@silver2row, i re-wrote that section to better explain the two common block names that occur with microSD cards. You need to use “lsblk” and use the base storage device name shown for the DISK variable. In your case you would use “/dev/sdb” as that would be the device… “/dev/sdb0” would be invalid, partitions do not start with “0”…
Regards,
Sir,
I think this is what I did. I typed in export DISK=/dev/sdb0 as in zero. I also may have, b/c I could not get the instructions to work, used export DISK=/dev/sdb1.
Anyway, now is the time when I cannot get my board booted. I cannot use the dfu 0 mmc 0 cmd in u-boot any longer and I am stuck.
Please send suggestions.
Seth
P.S. If I used sdb0 or sdb1, please let me know if you know of a workaround. Also sir, on the mount and format partitions sections, I have been clumsy to say the least. I used sdb, sdb0, and sdb1.
@silver2row, why did you add a “0” at the end of /dev/sdb? You should have used “export DISK=/dev/sdb”
Start again from the beginning, your eMMC is likely in a corrupted state.
Regards,
Yes Sir,
Should I rm -r and then reinstall everything?
Seth
P.S. B/c if that is the issue I have made myself come into, I cannot use dfu 0 mmc 0 still. Is there any workaround?
