-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Dear luke, I found this project that is similar to Haskell. IIRC, you said you'd like to use Haskell as it can be formally verified when designing what will hopefully be a silicon FLOSS processor. So, I think this project might interest you. https://clash-lang.org/ I hope you're doing well.

Pluton: M$ firmware and TPM to be built into your processor...
by David Niklas 13 Dec '20

13 Dec '20

Hi, It has been a while since I posted. Today I have bad news. Apparently, M$ has been working with AMD, Intel, and Qualcomm to place a new type of TPM into their CPUs, APUs, and SoCs. It's already inside of the new XBox processors. It runs firmware which is, according to M$, produced by them. Here's an official link, and a tech site link for those of you who don't want to visit M$'s site. https://www.microsoft.com/security/blog/2020/11/17/meet-the-microsoft-pluto… https://www.anandtech.com/show/16269/microsoft-pluton-hardware-security-com… I've done some research googling, but at this stage the data on what sort of access this new processor has and what it can do is anyones best guess. It sounds like the firmware might have unrestricted Internet access: "One of the other major security problems solved by Pluton is keeping the system firmware up to date across the entire PC ecosystem." I hope I'm panicking unnecessarily... David

Hi, sorry to interrupt - does that look like we're not getting our EOMAs this year again, if ever? How people are moving forward with their computing needs? What's the 'next best thing' to invest here? George

Any progress?
by Jan Wielkiewicz 04 Nov '20

04 Nov '20

Hello Luke and others! Are there any news about the cards? We're slowly reaching the next estimated shipping date (30 September), so let us know if there's anything new (I know the answer for the shipping date is the same as always). I also have a stupid question: would it be possible to combine the power of several computer cards, so that all GPUs together would be capable of running real time 3D graphics? Also good job with Libre SoC, I look forward to see it ready and working! Thank you for your commitment to libre hardware. Proprietary hardware is really annoying and often unusable, especially on free operating systems, making their adoption harder. Your work is crucial. Jan Wielkiewicz

OpenPOWER virtual coffee continues every Tuesday UTC 22:00
by Luke Kenneth Casson Leighton 08 Oct '20

08 Oct '20

with many thanks to Hugh Blemings the Virtual Coffee calls were a lot of fun. in LibreSOC we liked them so much that it would be a shame to stop. the time and day is the same: every tuesday, UTC 22:00 hrs. this turns out to be a reasonably sane time for both US and AU, a little late for EU though. it is on jitsi meet, if you would like the URL (which does not have a password set) please email me and i will privately provide the link. if you cannot use jitsi meet directly (web, android) there is a dialup number available as well. discussion is, as usual, eclectic and entirely informal. even OpenPOWER can be a topic for discussion. l.

Free ASIC fab. for open designs
by Philip Hands 26 Aug '20

26 Aug '20

Hi, This seemed like it might be of intrest to someone here: https://fossi-foundation.org/2020/06/30/skywater-pdk It seems that is a 130nm fab, based in the USA somewhere. It came up in the "Debian Electronics BOF" session at DebConf20 (which is going on this week, as an online event): https://debconf20.debconf.org/talks/86-debian-electronics-bof/ The video of that session should appear within a day or so. Cheers, Phil. -- |)| Philip Hands [+44 (0)20 8530 9560] HANDS.COM Ltd. |-| http://www.hands.com/ http://ftp.uk.debian.org/ |(| Hugo-Klemm-Strasse 34, 21075 Hamburg, GERMANY

EOMA68-A20, MD 1.7 severe Power Problems
by Pablo Rath 26 Jul '20

26 Jul '20

I am very sorry to inform everyone on this list that I had a severe power problem with my Micro Desktop 1.7. I applied power to the DC Jack and the area right to the jack burned out. (see attached picture). One thing that I noticed today was that UART worked when the card was powered up whilst attached to USB OTG alone (DC Jack on MD not connected)! But according to the wiki this should not work at all because of the Y6280 current control IC set at 1A acting as a diode in this case. When I applied power only to the MD I noticed that UART output was complete garbage (random characters). I don't know if only sometimes or everytime. When on DC power, board in FEL-mode with no card and pressing '2', then connecting USB OTG and booting U-Boot sunxi over FEL everything worked flawlessly. As I said I am very sorry that I screwed up. Luke, do you have any ideas what went wrong? Do you think this +also destroyed the computer card? If the error is on my side (embarassing but still the better +case) I will have to swallow the bitter pill that I screwed up badly. I am still going to cover the costs of computer card and MD so there will not be a financial loss to the project. I am very disappointed as I have made could progress. Had sunxi U-Boot, sunxi 3.4.104 kernel running and booting Debian Stretch rootfs... On the other hand if this is a general problem better we know it now and can take the necessary steps. Pablo

2.7.5 latest pre-production boards tested and working
by Luke Kenneth Casson Leighton 26 Jul '20

26 Jul '20

yes, a few months ago, mike sent me 2 new prototypes, using "single-panel" PCB from a high-quality manufacturer. i tested them just now (yes, long story, very busy with Libre-SOC) and they work fine. boot off of the usual micro-sd card i've been using. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68
