Mraa-gpio list: No Pins

rolly · July 10, 2019, 3:39am

Hi, I am trying to use the gpio pins and I followed the steps in the wiki, I am on ubuntu mate desktop. But I have this, could anyone please help? Which kernel on RockPi 4 supports mraa?

rock@rockpi:~$ sudo mraa-gpio list
No Pins
rock@rockpi:~$ mraa-i2c list
rock@rockpi:~$
rock@rockpi:~$ uname -a

Hi all,
I tried further to compile the mraa myself, but it fails with errors:

Hi all,

I can confirm GPIO works on Ubuntu Mate Desktop with direct access to the /sys/class/gpio bythe following code to blink an LED. I am sure that it is the problem of libmraa itself. Can anyone please take a look at the problem?

Thanks to all.

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <fcntl.h> //define O_WRONLY and O_RDONLY

#define SYSFS_GPIO_EXPORT “/sys/class/gpio/export”
#define SYSFS_GPIO_RST_PIN_VAL “157”
#define SYSFS_GPIO_RST_DIR “/sys/class/gpio/gpio157/direction”
#define SYSFS_GPIO_RST_DIR_VAL “OUT”
#define SYSFS_GPIO_RST_VAL “/sys/class/gpio/gpio157/value”
#define SYSFS_GPIO_RST_VAL_H “1”
#define SYSFS_GPIO_RST_VAL_L “0”

int main()
{
int fd; //open port on /sys/class/gpio# echo 157 > export
fd = open(SYSFS_GPIO_EXPORT, O_WRONLY);
if(fd == -1)
{
printf(“ERR: Radio hard reset pin open error.\n”);
return EXIT_FAILURE;
}
write(fd, SYSFS_GPIO_RST_PIN_VAL ,sizeof(SYSFS_GPIO_RST_PIN_VAL));
close(fd);

//set direction /sys/class/gpio/gpio157# echo out > direction
fd = open(SYSFS_GPIO_RST_DIR, O_WRONLY);
if(fd == -1)
{
printf(“ERR: Radio hard reset pin direction open error.\n”);
return EXIT_FAILURE;
}
write(fd, SYSFS_GPIO_RST_DIR_VAL, sizeof(SYSFS_GPIO_RST_DIR_VAL));
close(fd);

//reset: push high for >100ns
fd = open(SYSFS_GPIO_RST_VAL, O_RDWR);
if(fd == -1)
{
printf(“ERR: Radio hard reset pin value open error.\n”);
return EXIT_FAILURE;
}
while(1)
{
write(fd, SYSFS_GPIO_RST_VAL_H, >sizeof(SYSFS_GPIO_RST_VAL_H));
usleep(100000);
write(fd, SYSFS_GPIO_RST_VAL_L, >sizeof(SYSFS_GPIO_RST_VAL_L));
usleep(100000);
}
close(fd);

printf(“INFO: Radio hard reset pin value open error.\n”);
return 0;
}

Hi, rolly

I use debian and install libmraa-rockpi4 from Radxa APT , both mraa-gpio and mraa-i2c can work.

I’ll test if it works on ubuntu later. If you’re in a hurry, try debian first.

Hi, @rolly

I’m glad to tell you that both mraa-gpio and mraa-i2c can work in ubuntu if you install it from Radxa APT .

tip: You need to first remove mraa-gpio installed from PPA.

Hi setq,
Thanks but I tried to purge and reinstall via radxa apt, but it still fails. Could you please show your steps to remove the ppa package?

Besides, my /etc/apt/sources.list.d/apt-radxa-com.list reads, is it correct?

HI setq,
Thanks very much and I confirm it works with radxa apt.
