<mripard> wens: earlyprintk doesn't use interrupts iirc
<mripard> it only outputs data, but doesn't read any
<wens> mripard: ok, i'll look into the new earlycon stuff, which uses DT, so should be cross platform
<wens> iirc it can read stuff in though

<fathead> libv: is the in-circuit buildroot URL for the SoMPi public/shareable? I'm still waiting for a response from them.
<libv> i do not see why not, but, i will try to finish the device page ASAP, and get the fex file and such included in our sunxi repos

<Inode> Seppoz: is there really an A40?
<NiteHawk> Seppoz: you're not referring to the 'rumoured'/marketing name of what later ended up as A31? http://linux-sunxi.org/A31#History
philippe_fouquet has joined #linux-sunxi
<NiteHawk> there are some hints (namely an Olimex blog post) that Allwinner may release a new quad core that's pin compatible with A20/A10, but it's unclear if that might be named A40
<wens> don't see any new a-series chips
<wens> seems like olimex has a33 prototypes, and is working on h3

<ajeandet_> Hi is there any interest in adding some hardware resources on the wiki such as kicad footprints? My point would be to add some resources to start making PCBs.
<libv> ajeandet_: as long as you respect licenses of the projects that you get the kicad files from, sure
<ajeandet_> libv: For sure, I plan to make them ;)
<libv> ajeandet_: sounds great :)
<ajeandet_> libv: I got some funding in my lab to make a kind of evolutive tablet, it would be for next year.
<ajeandet_> libv: I order some chip from olimex today, next step would be to get a working DDR3 layout on kicad I would share as a base design.
<Inode> ajeandet_: a tablet that finally features an easily detachable/replacable battery would be great :)
<Inode> are you using any of the allwinner tablet reference design schematics at all?
<ajeandet_> Inode, To be clear I work for a research lab, I will share everything I will make but wont sell anything.
<Inode> that's cool, i'm just asking out of personal curiousity
enrico_ has quit [Quit: Bye]
<ajeandet_> Inode: I will use Olimex designs as reference since they share schematics. And yes the battery should removable.
<ajeandet_> The idea is not to make it really slim but to add an FPGA and turn it into an oscilloscope, a generator or anything custom.
<libv> ajeandet_: olimex does full oshw :)
<libv> for all but their soms, as there is a market for people who are afraid of oshw
<ajeandet_> libv: Yes and no since eagle isn't, in my opinion eagle isn't much better than Altium or any other
<libv> ajeandet_: yeah, tsvetan is aware of eagle not being the most open source friendly solution
<libv> but still, nobody currently does match olimex with respect to oshw
<ajeandet_> libv: that's why sharing the DDR3 layout would be a big kickoff, and yes Olimex is the best I agree.
_massi has quit [Remote host closed the connection]
<ajeandet_> libv: the first prototype will be based on their a20 som.
<ajeandet_> One more question, does anyone tried to find the max speed of UARTs on A20?

<Inode> according to the A20 user manual section on UART, page 648/835: baud rate = (serial clock freq) / (16 * divisor)

<Inode> page 51 has a table describing APB1_CLK_DIV_REG, and it features a bit field labelled APB1_CLK_SRC_SEL that apparently defaults to 0x00 (OSC24M) - assuming that's a 24MHz clock divided by 16 at best, 1.5MHz or ~1500000bps?
