ZRouter - we shove FreeBSD into a DLINK router
A couple of weeks ago
I ran around the Habra like mad in search of a recipe (how to revive the dead DIR-620 router).
The main problem was that the native 620 firmware did not accept the Verizon U175 modem. And after several DDWRT firmwares, I finally found the very one that ditched it and turned it into avegetable switch stupid.
But what happened next read under the cut
Trips to local specialists were not crowned with success, some tried to connect to the console but failed, they recommended to change the chip itself on the programmer, others said that Bobby had died completely. But still it was a pity to part with their blood 50dol. And I ordered a DCA-510 cable in one of the online stores (this is again the whole story) and re-soldered it to fit my needs.
Further, using the visual aid and the scheme:
and made myself access to the u-boot.
After that, I managed to install on it a DD-WRT from ASUS rt-n13u which I installed for the first time. But this time I already had a console and a desire to experiment with FreeBSD.
FreeBSD is a start.
At first, I was on the Internet on the wiki where the compilation of the BDD kernel was done for this chip. Skompilil tried, well, it starts up and looks for a bootp.
But further searches led me to the site zrouter.org. On which I was lucky to download the very firmware that will be discussed.
To begin, following the advice of the site do the points:
Next, I created the start.sh file:
just for easy start via screen
Further, in the best traditions of FreeBSD, a text interface appears.
With the choice of parameters of the platform and build
')
for DIR-620, chose Device -> DIR-620, Target -> zImage respectively
So far, I do not recommend using Save \ Load items, as due to them, my build did not reach the end of falling out with an error:
Click on Build and look forward to creating an image.
Next, raise the tftp and try to boot.
Since I already had DDWRT on my router and didn’t really want to demolish it, I first used point 4 U-boot followed by tftp test.bin and bootm, but I didn’t want to load the packed kernel (it gave an error when checking lzma). Then, following the advice found in the open spaces, www.dd-wrt.com tried to load according to item 1. And the load of the packed kernel went. But stubbornly not seen rootfs.
Gathering arrogance, I wrote directly to the developer: Oleksandra Rybalko . In conversation and samples with which we spent the next few hours (more precisely, about 3 days but worked in the evenings for a maximum of 1-2 hours).
As a result, it turned out that the ZRouter kernel is looking for rootfs at the address in flash memory and not RAM. After flashing the router on point 2 of the U-boot, I finally got the coveted FreeBSD.
The web interface is very simple, I would even say spartan.
In the settings were found as befits: DHCP, PPTP, PPPoE, 3G, Wifi (temporarily disabled).
Actually their configuration is the same for any such things, regardless of the firmware and manufacturer.
It is worth noting, however, that the Update button does not save data. This is done by the Save settings button in the main menu.
Further setting 3G modem-a (I had to change only the link to the device /dev/cuaU0.0), save the settings (required), reboot (required).
The modem went up with a bang.
Results
1. The firmware works (actually through it now and the Internet on which I write here)
2. There are problems with Wifi (according to the developer’s claims, it’s working at about 60%, but it’s not yet configured in the browser)
3. 3G modems are determined with a bang (at least from the tried firmware Dlink original, DDWRT, ZRouter, only the latter normally identified my Verizon U175
Rake:
1. Be sure to use the fresh kernel from the ZRouter repositories.
2. Be sure to flash and do not try to run from RAM
3. Update does not record data, so it is necessary to forcibly record everything through the menu.
