SG-3100 M.2 install

It may also be booting from the m.2 and then mounting root from eMMC confusing the issue.

@eyes said in SG-3100 M.2 install:

From the instructions I should use m2dev=0

To be able to boot from the M2 SSD, m2dev should be 1.
and setenv bootcmd 'run setLED; run m2boot;'

I always wipe the entire eMMC disk when using SSD to avoid the problem described below:

https://docs.netgate.com/pfsense/en/latest/troubleshooting/multiple-disks.html

Edit:

In addition to the described above, I usually set:

Create the file /boot/loader.conf.local and add to it:
hint.mmcsd.0.disabled="1"

@mcury

I might want to try to wipe the drive then

Before i do that. This is the M.2 I use.

Sata III is working with the device right?

If you were able to install to it as ada0 then it should be fine.

What is the command in U-boot to erase the eMMC? if i want to wipe it clean.

I cant do it in root, since its the active partition

I don't have that written down here, but as far as I remember, you will need:

1- Connect to the console
2- Boot the device in single user mode:

At the SG-3100 console press any key to interrupt the boot loader when you see:
Hit [Enter] to boot immediately, or any other key for command prompt.

At the prompt enter: boot -s

That will boot in single user mode to a question asking for a path to the shell, just press return to reach the # prompt.

3- Run the command to wipe the eMMC as described in the link posted above;
Wipe the first 1MB of the disk
dd if=/dev/zero of=/dev/mmcsd0 bs=1M count=1 status=progress
or:
Wipe the entire disk:
dd if=/dev/zero of=/dev/mmcsd0 bs=1M status=progress

Then, boot through USB drive and perform a normal install using ada0 drive.

@stephenw10 can you confirm if these steps are correct ? I really don't recall exactly what I did at that time..

You should be able to run run m2boot manually then choose single user mode to reach a prompt you can erase the eMMC from.

Or at the uboot prompt try: mmc erase 0 400000

I recently updated the 3100 M.2 install doc with better info on all this, so make sure you are following the new doc and not older instructions:

Just to still my curiosity...

I checked my Putty log from serial port and as far as I can see I did not run any printenv/setenv command when installing the 22.05 software at ada0.
Also I looked up in my downloaded manual which do not contain this recently added commands.

Because I installed m.2 devices in two appliances at nearly the same time without running in trouble, my question is: was that luck or does the issue only occur in special circumstances/releases?

I would have expected it to apply there if you added the SSD. Though looking at the internal bug report I opened for this it applied in 22.01-Beta and was present in 23.01 but I couldn't say for sure if it happened in 22.05.

I found solution for the m.2

setenv m2boot 'scsi reset; fatload scsi 0:1 200000 ubldr.bin; go 200000;'

saveenv

reset

Then it should boot correctly from the m.2

It looked like this for me as default.

setenv m2boot 'scsi reset; fatload scsi 0:0 200000 ubldr.bin; go 200000;'
