ChibiOS Free Embedded RTOS

[update: It works a bit better if you use the right AF ]

I don't understand: I used to have it working, but now it no longer works...

Anyway, when I send something over SPI using
(MYSPI is defined to SPID2 here), it does spiStartSendI(spip, n, txbuf); and then suspends. It is waiting for the DMA transfer to finish, but I never see the wakeup happening.

I'm now doing the SPI from a second thread, so that I can use my own embedded debugging code to debug things:
This is the SPI2 peripheral. The third word seems to indicate: TXE. So the SPI module is waiting for DMA to fill the TX buffer. Correct?

So examining the DMA module:
the interrupts for DMA5 are enabled.
Here everything looks good, except for the count: it is zero.

Further suggestions?

P.S. SYSCFG->CFGR1 is zero.

Are debug options enabled in chconf.h?

The usual SPI demo for the F0 runs normally here.

Yeah. That's a plan. First modify the example get that to work, and then try to re-integrate with the source I have. Thanks for the suggestion. (it works better with the proper pin AF's selected, but not quite yet. It might be set too fast. I'll dust off the logic analyser first).
