how to set MTDs writeable?
December 01, 2016 02:08PM
I just came across this:
root@publik:~# fw_setenv ipaddr 10.9.1.208
Can't open /dev/mtd0: Permission denied
Error: can't write fw_env to flash
root@publik:~#


How do i fix this?

2 Pieces NSA320 , u-boot 2016.05, debian with Kernel 4.8.3, Several Mac and Linux boxes connected.
More into soldering than programming. Location:Hildesheim, Germany

Possibly, it meant that your u-boot env bootargs is not set up properly to tell the kernel about the MTDs. Pls get the listing of:

uname -a
cat /proc/cmdline
cat /proc/mtd
dmesg | grep -i mtd
dmesg | grep -i 0x000
fw_printenv

Everything in your system looks normal!

If you have serial console, then reboot and post the entire serial console log here. Perhaps something out of the ordinary happened during boot.

Re: how to set MTDs writeable?

Hello,
i think i fried the out port of the UART. This must have happened while i was double checking, and crossing the Serial lines. I checked the PCB, and the serial out line runs right into the Kirkwood SoC chip, no other semiconductors involved, as far as i can see. The voltage on the Serial out is about +3 Volts (in silence) and the data transmissions drop it to about +2.6V instead of 0V where it ought to be. And my 3.3V <-> USB converter( i use this one:http://www.ebay.de/itm/FT232RL-USB-TTL-FTDI-Serial-Adapter-Modul-5V-3-3V-fur-Arduino-193-/122228183676?hash=item1c755e127c:g:2m0AAOSwKOJYKEOQ) doesnt trigger on these low changes.
I checked this with an oscilloscope. Otherwise the Spikes are in good rectangular shape.
This Weekend maybe i hook a Transistor to the out port, to re-establish the full 3.3V to 0V Level, and thus reestablish the Serial port.
I will keep you updated on the progress.
Another thing i noticed: The netcat console also doesnt show anything, on both NSA's, during the whole boot process.
You already have my current environment, i even made another Linux box in the Network connect to the nc Server.
10.9.1.200 nc Server cmd line:
nc -lu  6666
10.9.1.222 nc Test client cmd line:
nc -u  10.9.1.200 6666
to ensure this is no Firewall etc. issue. Text i type in either Computers window appears in the other window, but only after i press <Enter>.
So maybe its a weird <CR> vs. <CRLF> issue? Shouldn't the characters appear instantaneously?
Anyway, there is still no boot log from any of the NSA's. Both have the exact same Environment, only the ip and mac addresses are different.

mtd partitions were not detected at all, i had to add to /boot/uEnv.txt
mtdparts=mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)

No idea what happened, fw_setenv iworked fine with 4.4.0 and 4.6.0

Thanks a lot.

mtd partitions were not detected at all, i had to add to /boot/uEnv.txt
mtdparts=mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)


The above did not make sense! The mtd definition in uEnv.txt is obviously wrong! and the cmdline showed they are wrong too. Since you don't have serial console, you could not see the boot process step by step.

Please remove the uEnv.txt and reboot. Post :

- dmesg
- cat /proc/cmdline
- cat /proc/mtd
- cat /etc/fw_env.config
- fw_printenv

Thanks a bunch !

PS: my serial console actually works, i have the Rx/Tx/GND pins bought out of the case, but the Pogo is not in a very easy to reach area. I can get a ladder and get the serial output if it's really needed :-)

No need to go that far :) Here is how to fix it.

As root:

cd /boot
touch uEnv.txt
echo "mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)" > uEnv.txt
Verify:
cat uEnv.txt

expected output:

mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)

Sync and reboot.

( facepalm for myself after realizing what was the issue )

It worked ... thanks a bunch Bodhi !
And i guess shivahoj must do exactly the same thing to fix his :)

I did a:
fw_setenv mtdparts 'mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)'
And now everything works with a empty uEnv.txt

People of the forum, remember: "mtdparts=mtdparts=orion_nand..." is NOT a typo, mtdparts= is supposed to appear twice. The boot scripts will cut-out the 1st "mtdparts=" and the the kernel needs the 2nd one.
