Hi there,
i’m a real hardware noob, but i tried to get a led (with integrated resistor) lid up at the GPIO Port 0. But it did not work. If i attach the led to between GND and 3.3V it lights up. But not wenn attached to GPIO 0 set to output and HIGH.
Is the GPIO Port 3.3V on high? Or is this a problem with the current firmware changes (FPGA addresses)? Has someone else got GPIO working the last days?
regards
It should work. I can try to replicate today. Few questions:
Yoel
Hey yoel,
thank’s for your reply.
it’s a creator board.
led = i think it has a integrated 220 ohm resistor, but not sure
when i have my multimeter attached, i can not meassure anything on 0 the other pins not 0 have a slight amplitude of 0.1 V
my code is:
namespace hal = matrix_hal;
#define INPUT 0
#define OUTPUT 1
#define PIN_0 0
int main() {
hal::WishboneBus bus;
bus.SpiInit();
hal::GPIOControl gpio;
gpio.Setup(&bus);
gpio.SetMode(PIN_0, OUTPUT);
uint16_t write_data = 1; // tried also 0
gpio.SetGPIOValue(PIN_0, write_data);
return 0;
}oops short update, after executing the above code, something get;s broken:
/usr/share/matrixlabs/matrixio-devices/fpga_info
IDENTIFY = ffffffff
VERSION = 0
maybe i broke something…
Trying to replicate now …
Hello @loom
Could you run the following steps:
I’m looking forward to your answer.

fpga_info before gpio_demo in the examples:
IDENTIFY = 5c344e8
VERSION = 10005
and after the gpio_demo:
IDENTIFY = ffffffff
VERSION = 0
i just have cloned the hal repo and tried it with the current master branch:
https://github.com/matrix-io/matrix-creator-hal.git
Just by executing the code? Did you also connect the LED?
Can you share specs of the LED used (maybe just a photo) and explain how you did the connection?
Thank you
i only run the gpio_demo with nothing attached to the GPIOs, to get the behavior from my last post. i have also disabled all malos services
Hello @loom
We found the issue, so it has been fixed in our new release https://github.com/matrix-io/matrix-creator-init/releases/tag/v0.4.2
Could you run:
sudo apt update
sudo apt upgrade
Thank You,
Kevin Patino
