AI? Really?

by Anders Gustafsson

Yes. I tried Operas Aria and asked a bit about HP1000 A-series. I started by asking the difference between A900 and A400 and got a reply that was partly correct, then followed up with some specific questions about the A400 that I happen to know rather well. It insisted that it had only 32Mb and it corrected itself. But the problem as always was that the answer LOOKED ok, but there was no way, without prior knowledge to weed out the errors. -- Med vänlig hälsning Anders Gustafsson, ingenjör

New DRAM (SIMM) board works but gives a parity error, only on cold powerup

by Anders Gustafsson

OK. As usual was the problem quite evident, once I understood it... I have two A400 boards. On that board I tested with I never took note of switch 8. It was unfortunately set to OFF indicating that there was backup power for memory. Thus the power lost flag was never set, which caused the parity error on startup. -- Med vänlig hälsning Anders Gustafsson, ingenjör

OT: not that classic but already old: Cubieboard2

by Holm Tiffe

Hi all, I've got 3 pcs. Cubieboard 2 SBC's with the Allwinner A20 SOC Chip on them. That's kind of a RaspberryPi SBC with an 2 Code Arm7hf on it. The boards are equipped with HDMI, USB, Ethernet (100Tx), SATA, SD Card slot and some 4G NAND Flash Cip on it. RAM is 1 Gbyte, CPU Clock is 996Mhz. Additionally I've bought some Base Boards for them, that's the DVK521 from Waveshare..contains the Baseboard, an Camera Module OV670, a 7" LCD with LVDS, a thermo sensor and other things.. Good HW in my eyes, but already outdated. I wnt to use the boards for some Home/house related stuff, PV, heating, Light control etc. and for that they should be more than enough. The Chips even have an graphics accelerator in the SOC. Now the Problem: as far as I know Allwinner has made some mistake using gnu/Linux stuff without any respecting the GPL. Because of that (if no other cause) most of the support Software on the net seems to be gone. There where some different Linux distributions for it, (Linaro, Cubieez etc) but most of the stuff isn't available anymore because of dead links. I've successfully build an modern Armbian image for them..but have endless trouble. The Xserver configutres an not existing Video Output, the LCD is unknown at all and if I manage to switch the X-server to the HDMI output using xrandr (only with tricks because it needs a session) the performance is like some old thick glue... Besides of that I had to fix an already for 8 years known Bug in the A20 Ethernet driver (it simpy has a more modern ethernet Unit as the A10 inside) that was'nt fixed at all. Armbian has only "community Support" fo those chips..which means that there is no support at all. If one asks for help the answer is more or less "find it yourself and provide a patch". I have an Linaro disk image that seems to be working, but there are some parts missing. The base distribution seems to be ubuntu 12.04 LTS (precise Pangolin) for armhf. I can't find a package repository anymore..(since that's long outdated). I've managed to install ssh by using an tarball of an ubuntu 12.04 armhf image for another board..and it works..but sshd is still missing. There are more modern disk images at https://mega.nz/folder/ZtwxCCJC#AIYHcTqz-ucjuzKnE9qD7A/folder/t0p2SBQD but mostly they don't even boot..possibly they using an newer/other uboot and uboot-envirnonment... Now the question: Is someone in the world still using those boards and has disk images/software for them? Again: I'ts not that much interesting that this is old linux, because I'll use that only inhouse in the lan, not browsing actual websites.. I'm a BSD guy and not know that much about Linux, especially such things as configurations for uboot etc. and there is none that I could ask for such things. Kind Regards, Holm -- Technik Service u.

Fwd: SBC6128

by Doug Jackson

Hi Dave, I'll send this to the group, I suspect my email made it into your spam. Doug ---------- Forwarded message --------- From: Doug Jackson <doug(a)doughq.com> Date: Tue, 14 Jan 2025, 6:05 am Subject: Re: SBC6128 To: <dave.g4ugm(a)gmail.com> Hi Dave, I was just researching the IOB6120 (I had an 8 at the end of the model.. sigh - memory is often faulty) WOW - I had no idea that existed. I also had no idea that the community picked up Bob's designs and ran with them so enthusiastically - I feel like I have been under a rock for quite a while. I would be very very happy to purchase your board + IOB that you have put together - If the enclosure is not ideal, I am very happy to update that - these little boards are awesome. Just let me know a Paypal address and shipping details.
