Archives at http://lists.laptop.org/pipermail/openec/ FYI actual location of the code and some other interesting info. I'll also go update http://wiki.laptop.org/go/OpenEC with this location as the location currently mentioned has really old code (2009). Perhaps this will also be helpful with OpenEC on Lemote Yeeloong work (FSF donated a few Yeeloongs to people who wanted to work on that a while ago, but as far as I know there has not been a lot of progress there.) cjb | djbclark: http://dev.laptop.org/git/users/rsmith/ec-1.75 for all your openec needs cjb | (it's actually the repo we're using to bring up the 1.75 right now) dilinger | cjb: is this xo-1 EC minus battery code, or written from scratch? cjb | dilinger: battery code's in there, AIUI cjb | the patent was on the NiMH battery charging, and we don't use those batteries anymore, only LiFePO4 dilinger | cjb: awesome dilinger | so is that imported into OFW now, or do you still build the EC separately? cjb | on 1.75 they're more independent than before cjb | they don't flash a new EC at the same time as flashing a new OFW cjb | so they aren't built together dilinger | interesting cjb | OFW also isn't the first thing that runs anymore cjb | the mmp2 has two cores, security processor and the main CPU (PJ4) cjb | comes up in cforth on the SP, that loads from SPI into SRAM and releases the PJ4 cjb | the SP keeps running cjb | which is neat because you can make it watch a GPIO/button cjb | and if the PJ4 hangs, you hit that button, the SP takes over the serial port again, and it has full access to RAM and peripheral state for debugging cjb | so there's an always-available method for getting dmesg after a crash dilinger | SP continues running OFW the entire time? dilinger | is it drawing full power, or is it some kind of low power mode (similar to the low power EC mode)? cjb | (cforth, not OFW) cjb | yeah, I think it's drawing power cjb | we'll have to work out how that's supposed to work later -- \|/ Daniel JB Clark | Activist; Owner FREEDOM -+-> INCLUDED ~ http://freedomincluded.com /|\ Free Software respecting hardware -- You received this message because you are subscribed to the Google Groups "loongson-dev" group.
