Hi Mark!
I inform you that I try to write a spi driver for the rk3328. Called
it rkspi (rkspi.c). Currently I have implement a early version of the
match and attach functions and it works.
It is based on your rkiic driver.
_The match function_

rkspi_match(struct device *parent, void *match,
Hi Mark!
I have installed the dtb package. And copied the rk3328-rock64.dtb in
the FAT boot partition. Now I see all boot messages from the kernel.
But with this dtb file, the ethernet is unstable:
$ ping 10.42.42.1
PING 10.42.42.1 (10.42.42.1): 56 data bytes
64 bytes from 10.42.42.1: icmp_seq=9
Oh... Sorry, i have over read your text where you have
explained the state of the rkgpio.

Hi Mark!
Thanks for the answer. That's very pity.
But i run in a other problem with the GPIO. I have written
the follwing small piece of code:
#include

#include
int main(int argc, char *argv[])
{
int fd;
printf("Open GPIO port\n");
fd = open("/dev/gp

Hello Mark!
I have found the necessary information to control the GPIO.
But what about the I2C and SPI interface?
I don't find usefull information about this. I want native
support for my projects. Don't want to make a software based
(bit-bang) I2C or SPI interface with the GPIO pins.

Hello Mark,
I just installed OpenBSD sucessfully on the ROCK64 media board.
That's very cool. Thanks for your good statement.
Best reagards,

Hello Mark,
I have an additional question. Don't want start a new thread for
this.
Are the GPIO, the I2C and the SPI interface working?
An how can i use this. Is there a short example code available?
I'm new in this. I have experience in bare-metal programming
with AVR devices. Now I want use th
