Re: Road to K64F port
Hey walkerstop, nice to see another person working in this area! I haven't tried using the USB peripheral on my Teensy3.5s — I was mostly interested in the SDHC and UARTs. But I did eventually hack a Teensy to allow me to attach a JTAG debugger, which makes debugging low-level drivers a bit easier (...

Re: MCP23017 init & data transfer
Do you have a pullup on the i2c lines? On the Kinetis parts, if you need a pullup but don't have an external pullup, I think you need to explicitly enable pullups on an open-drain pin (I don't think the PAL driver can do this, you need to do it explicitly). The i2c peripheral might be hanging becaus...

Re: Road to K64F port
FYI, I've been pushing some changes to my fork of the repo at https://github.com/wiml/ChibiOS-Contrib , and I'll be making pull requests to the main chibios-contrib repository as individual parts become more mature. Let me know if you try to build from those branches and fail, in case I've forgotten...

Re: SDC LLD development questions
Hmmm, OK. But if it is implemented, what is it supposed to do? Or, how do I know whether my LLD should implement it or not? Is it related to the DAT0 BUSY signal?

SDC LLD development questions
I'm writing a LLD for the Kinetis K64F's SDHC peripheral. I have a handful of questions about how the higher level driver expects the LLD to behave. I can make guesses about some of them but I'd rather have the info from a more authoritative source My main question right now is the sdc_lld_sync() fu...

Re: Road to K64F port
I haven't published anything. I assume the best way to do so would be to make a fork of the contrib repository on github so that it can be merged in at some point. I am unlikely to have the time to maintain this port once I'm done with this project, but there seem to be many people who have some int...

Re: Road to K64F port
For what it's worth, I've also been working on a K64F port, for the Teensy3.5. I'm at the point where the basic ChibiOS/RT tests run, and I'm working on the one or two drivers I need.
