Ciao guys,

I'm currently working on ArgonKey, which is a 96 board with a
STM32F412
plus a bunch of motion and environmental sensors.

I'm exploring the possibility to put in place the communication from
HiKey to ArgonKey and I noticed that the stm32 SPI environment
already
implements the SPI_SLAVE communication. Does somebody have already
tried
it out and know what the status is? Is there any example (doesn't
seem
so) where I can get a look from?

Thx,
Arm

Thx Tomasz,

You probably need the first patch, and the second is an example how
to
do it. Note however the API has changed a bit, you'll have to
check.

It seems quite old. Why hasn't it been merged yet?
Is there something wrong that prevent it?

It has not been rebased against latest SPI API changes, thus why it
can't be merged. But it's a fine PR besides that.

Hello Thomasz,

Quick update before leaving for the week.

I took the patches suggested by you and I prepared
a very simple test environment. I have an issue
though: it seems that I'm not able to consume data
at the proper speed and OVR error is found in SR.

Just for testing I tried to comment the error out and
what I see is that I receive 1 byte evry 3.

I think I can slow down the spi master, but I think that
we would need to add DMA handling to stm32 spi. Is there
any plan?

Thanks,
Armando
