For example, I compile my own kernel for a MIPS-based device I occasionally use, but it still runs the standard distribution of Debian. People have "spun" their own custom distributions for various devices, but that usually happens out of necessity (using an unsupported architecture variant, for example) and/or under some impression that things can be "optimised" for a particular piece of hardware. But it should be the last resort if only because distributing the software will generally bring with it a significant support obligation. (The distributor will need to offer the software semi-permanently with corresponding sources and ongoing updates.) I imagine that Luke will try and stay as close to the upstream distributions as possible. That's what I would do, anyway. Paul P.S. The effort of "spinning up" a distribution is arguably a lot greater than just getting a bootloader and kernel working for a device, which is why I was surprised that he dropped the jz4775 card, given that it only needed confirmation that u-boot and the Linux kernel were compatible. But then again, he also wanted FSF "Respects Your Freedom" certification for the distribution, and none of the certified distributions support mipsel: Debian does (and is not certified), but gNewSense (being Debian filtered for RYF certification purposes) does not presently (and without suitable hardware probably won't in future, either). ___ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk

I imagine that the supported gcc version will be that provided by the distributions being offered. For Debian, you can find out versions by searching on the packages site: https://www.debian.org/distrib/packages Searching for "gcc" should provide results that employ descriptive package versions corresponding to the actual gcc version involved in each case (although you may need to strip off prefixes like "4:" and suffixes like "-1" as in "4:6.1.1-1" to get "6.1.1"). I see gcc 6.2.0 on Debian unstable, myself, but that's on i386. Nevertheless, the supported architectures tend to offer the same versions of things if at all possible. My cross-compilers seem to be 5.4.0, but an update is apparently pending with those. I can't answer the specific questions about the A20, but maybe the gcc ARM- related notes can provide some answers. For example: https://gcc.gnu.org/onlinedocs/gcc-6.2.0/gcc/ARM-Options.html Paul ___ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk

That may change, as it needs only some license clarification on some published code from AW. And knowledge of the HDMI PHY model they used (which differs from the previous generations of HW). Do you have contacts inside AW for the groups that created this chip, maybe you could try a bit of lobbying in that case...

[Arm-netbook] Gamechangers GO Course
well, i signed up for the gamechangers go course that my friend informed me about. the course is specifically targetted to encourage people to use wisdom and integrity in their purpose, with the primary focus being on "changing the game" in their chosen field. it sounded perfect, and exactly what i need, so i signed up. the cost is $3,000 and i have negotiated payment of that over 12 months, or until such time as i raise sufficient income from sources *not* related to the crowd-funding campaign (which presently total around GBP 700 and there is more on the way). the first assignment is here (discussion online took place at 5:30am this morning...) and was around the following: http://gcgo.lkcl.net/2016_course/prompt_1/ and my response (which you are all invited to comment on) is here: http://gcgo.lkcl.net/2016_course/prompt_1/lkcl/ now, as the course is *defined* as "encouraging its participants to act with integrity and wisdom in their chosen game-changing life purpose", i was a leeetle bit surprised when, without any discussion, consultation or consent, my inbox was flooded with signup demands for proprietary privacy-violating services, accompanied by a message that all communications forthwith regarding the course would henceforth take place exclusively through the same. oink. a series of increasingly-specific communications with the organisers was therefore escalated, and the proprietary SaaSS subscriptions cancelled (for me). i have therefore set an assignment for the organisers of the course, for them to provide satisfactory answers for both myself and for you. you are therefore invited to participate in the discussion of the questions raised (please do not edit them yourself): http://gcgo.lkcl.net/2016_course/organisers_prompt_1/discussion/ where the background and questions for the organisers are here: http://gcgo.lkcl.net/2016_course/organisers_prompt_1/ the purpose of writing that to the organisers should be fairly clear. any questions feel free to raise them here (or in the discussion as appropriate) l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68 ___ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk
