Re: Serial console access

Just verified and the board on the spare unit is in fact an RF1 2011. Did not re-run the beep test. I guess I may have suffered from an occupational hazard, starting the count from 0 instead of 1.

Re: Serial console access

Well, I just checked with a spare unit and I found Rx at 3 and Tx at 4. Don't know why that didn't work out for you.

Re: Serial console access

That's the one ;) Shamefully, no. I did in fact not register which pins represented what. There might be some old forum post where I do mention them though. As I happen to have multiple units I opted for the special connector which makes it plug-and-play for every board. But you can simply "beep" th...

Re: Serial console access

Pretty sure that the FTDI galvanically separates input and output. This makes pretty good sense and I'm assuming the CP2102 does the same. In fact if I remember correctly Excito themselves had some type of electronic buffering between the 9-pin RS232 plug and the front header on the B3 board (Johann...

Re: Debian 10 "Buster"

I just upgraded and it worked flawlessly. One thing I'm still tracking is why Shorewall doesn't see the iptables NAT modules any more, but I don't believe this to be a kernel problem. May like to check kernel config anyway. There have been some changes to Netfilter config names and whether or not t...

Re: Debian 10 "Buster"

For other curious b3-fans, the kirkwood-b3 device tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/kirkwood-b3.dts Yes. In case you should want to compile your own kernel, do note the 'gpio-led' section. The default state for these leds is in fact 'off...

Re: Debian 10 "Buster"

Those names you refer to are the so-called 'Predictable Network Interface Naming' names. That has actually been around for quite some time now, at least 5 years, and if it had applied to the B3 you would have already encountered that issue. As it stands, eth0 and eth1 are defined as such in the devi...

Re: Booting b3 without battery or working CMOS clock

Must be something else. I have a box that I use for maintaining the Bubbagen OS and that hasn't had a good battery for years already. That box never fails to boot.

One other thing to note is that the led should be coloured purple during boot. Red indicates an error.

Re: How to boot a b3 in rescue mode with Debian

You probably used an unsupported USB stick. It's a bit tricky to say which ones are supported though, but it's all about the internal chip. As a rule of thumb it needs to be USB2 and its capacity should not exceed 8GB. Most chance of success appears to be with the cheapest possible USB sticks, often...

Re: mybubba.org still in use? Can I let it expire?

Hi Johannes, Wasn't aware that mybubba.org was yours. Thought Ubi registered it for hosting the Excito services temporarily as these were being transferred to Rodeus. Seems like the domain is still completely controlled by his servers, but it doesn't resolve e.g. my easyfind name and there's no (old...

Re: b3 keeps resetting ** File not found uImage **

Some stuff like having a separate boot partition might not be needed. Probably worth noting that the various newer environments published in the development forum all do in fact already have a separate boot partition. At least in the case of Arch, Gentoo and Bubbagen this boots an interstitial kern...

Re: b3 keeps resetting ** File not found uImage **

Sorry, no, not reset. What I meant is that the u-boot image itself contains default values for several/most/all of the variables you see being listed in the environment. Since the u-boot image is specifically created for this device it is very likely that the defaults are in fact the same as the val...

Re: b3 keeps resetting ** File not found uImage **

1) No, the flash should not touch the u-boot environment since this contains values unique to your device. I do believe that the flash image does contain defaults for at least some of the environment variables though and thus you'll likely get a better result from deleting a key then guess at its or...

Re: b3 keeps resetting ** File not found uImage **

sataroot and satadev are okay. sataboot seems incomplete to me, but that may be because you are running a custom u-boot version. Whether or not the defaults that are apparently implied (like the "uImage" file name) work out the same is impossible to judge by me. In any case, sataboot in my environme...

Re: b3 keeps resetting ** File not found uImage **

ehm... So what are the present values for "sataboot", "sataroot" and "satadev"?

Note: if dumping the full environment do anonymize the eth*, serial and key values - these values give access to your easyfind account.
