In this case, you can reference:
https://github.com/apache/nuttx/blob/master/drivers/rpmsg/rpmsg_port_spi.c
https://github.com/apache/nuttx/blob/master/drivers/rpmsg/rpmsg_port_spi_slave.c
which contains the common logic to send/recv messages on spi bus async.

Hello Xiang Xiao,
Can you connect me with Donny or can you help me to understand spi_slave
semaphore "unlock" ?
Looking into spi_slave_driver.c:330
while (priv->rx_length == 0)
{
remaining_words = SPIS_CTRLR_QPOLL(priv->ctrlr);
if (remaining_words == 0)
{
spiinfo("All words retrieved!\n");
}
else
Awesome! Thank you Xiang :-)

Hello All,
I did a dummy question, in master branch, spi slave implementation already
blocked until new data is available. I wasn't working in the master branch
but I will switch to.

Hello Xiang Xiao,
thanks for sharing with me about rpmsg, to be honest it is new for me =/, I
was locked in baremetal for several years. For now I cannot use it because
my host mcu is running baremetal (maybe in the future we will change it). I
developed a simple protocol using ack and nak whey to
Yes, we use DMA for both SPI master/slave, but DMA is more related to the
driver not the framework.

One question by the way someone asked me recently - can NuttX SPI Slave
work in DMA mode? :-)

am developing is an spi slave. Up until now, my application has been
