Hi

I'm a new DD-WRT user with two questions for you.

I tested r53662 mini on my EX6200 and I can't figure out how to mount a usb drive, first I formatted it to fat32 on a linux computer using GParted - copied a file to it from win10 machine and when I choose 'Automatic Drive Mount', using ssh I can't see the file when I connect using Winscp.

I can copy the same file over using winscp, I can run it perfectly fine, I can see it active using 'PS' but if I shut down router and restart it file is gone from sda1.

I also tried turing off automount and added a startup command for mounting drive using UUID but file is still missing after a reboot.

mkdir -p /mnt/data
mount -t vfat $(findfs UUID="3D73-1EBC") /mnt/data

As you might have guessed I'm not not very well known in the linux world.
Any ideas for the correct way to make this work ?

Also this is more a bug, under Administration/Management there is an option to choose between 800MHz and 600MHz clock, standard is 800MHz cpu / 533MHz memory clock.

If you set cpu to 600MHz memory is set at 400MHz.

But if you now set it back to 800MHz memory clock is still 400MHz

Factory Defaults via gui won't get it back to 533MHz, reset button on the back won't help either but 'nvram erase' from the command shell and a reboot will set memory at proper 533MHz.


Sorry for the wall of text.
Thanks

You can manually overclock: https://wiki.dd-wrt.com/wiki/index.php/Overclocking

for USB see: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=335183&start=4

Thanks, I now formatted the drive with free-partition manager and following the example with 3 partitions with fat32, opt and jffs.

All 3 partitons now is automounted during boot but files I write to any of those partitions using winscp is gone after a reboot of the router - I can't understand why that happens, anyone know why ?

Also, having a look at cpu and memory frequency using 'nvram get clkfreq' only shows cpu frequency but setting cpu/mem clock using 'nvram set clkfreq=800,533 nvram commit' fixes that - Thanks
I don't know if backplane frequency is altered, its not listed.

First of all do not use the Commands box to execute commands, use a proper telnet/SSH client e.g Putty.

Not sure what you did wrong you can use WinSCP to write to your USB stick, maybe you did not write to the USB stick but to the router?

Most of us use Samba (SMB) to write directly from our clients to the USB stick.
But WinSCP should also work.

The GUI to overclock CPU and RAM speed has been stripped as people tend to brick their routers with it. So you must set it manually

[ZuluZebra]

Very likely your on to something, if I copy my file to /tmp/mnt/sda1 will the file not be copied to the usb pendrive ?

[egc]

If that is the mount point you can copy to it.

You can view your mount points with mount:

[ZuluZebra]

My mount points is missing even if sda1,2,3 is visible in WinSCP - I have tried writing to jffs and opt but both are read only file systems.

[egc]

That is odd

Have you tried a reboot?

[ZuluZebra]

Oh yes, several times - also tried 2 other usbpens, I will try a full reset just to see if anything I did earlier perhaps messed something up.

I'm using the correct one, the mini is the only one for this extender.
I made sure I did't use the Router Database

[ZuluZebra]

I tested a few older ddwrt versions, could not make usb mount.

I flashed Netgear's EX6200_V1.0.0.38_1.1.52 and the same usbpen mounted all 3 partitions and I could see and download a file I wrote to the fat32 partition so now I know the extender hardware is ok and same with usb pen.

I will test r53662 more tomorrow.

@bushant:

I presume that since the files are ~6.9MB in size and the hardware is Broadcom Northstar, it's considered a "mini" vs. "std" on similar hardware with larger flash space.

I can always look through the code repo or annoy the head master, but that is my best presumption given the information in hand without further research.

[ZuluZebra]

Thanks any help will do and let me know if you need me to try something on my end.


I updated to r53694, erased NVRAM , started router and activated Core USB Support ,USB Storage Support and Automatic Drive Mount.

If it helps you this is the serial connection log after enabling usb support using same usbpen as I used with Netgear V1.0.0.38_1.1.52 fw.

Ok, I finally got it working - according to this user and his ticket usb was working using r45767 the very first release where usb support was added for the ex6200 - ticket 7345

I flashed it and my drives did not mount, I then tried ntfs and for the first time it worked fine and gui shows the used diskspace too but I could not write to the drive as winscp gave a 'Broken pipe' error.

I updated to r53708 and 'Broken pipe' error was gone, rereading BrainSlayer's post he writes that he added 'samba,exfat and ntfs3' - there is not a word about supporting ext2,3, or 4 filesystems.

Perhaps other filesystems was not added because the ex6200 only has 8MB flash memory.

I also tried exfat and it works just as fine as ntfs, files now does not disappear after a reboot and everything seems just fine.


Hehe I'm a happy camper even if I spent over a week looking for a solution for this usb problem - hope this post is helpful for others with same problem.

I'm going to treat myself to a beer.

Thanks
