Hi to all.
Sad story.
I have been connecting PCM5102 DAC to my Raspberry Pi 3b and damaged BCLK pin of my Raspberry by static electricity.
Have checked on another Raspberry.
PCM5102 - normal Raspberry
VCC -> VCC ; GND -> GND
BCLK -> GPIO18 pin 12. Oscilligraph shows signal about 2.8Mhz
LRCK -> GPIO19 pin 35. Oscilligraph shows signal about 44.1 kHz
DATA -> GPIO21 pin 40. Oscilligraph shows variable signal 120-250kHz
At that time DAC works correctly, there are no problems. Sounds well.
The same configuration on damaged Raspberry
PCM5102 - damaged Raspberry
VCC -> VCC ; GND -> GND
BCLK -> GPIO18 pin 12. no signal. pin short circuited to GND.
LRCK -> GPIO19 pin 35. Oscilligraph shows signal about 44.1 kHz
DATA -> GPIO21 pin 40. Oscilligraph shows variable signal 120-250kHz
And there is no sound.
So the question is - how can I using SSH and MobaXterm change BCLK pin of I2S interface from 12th pin GPIO 18 to an another raspberry’s GPIO?
Unfortunately i have almost no skills in programming, but hope i’t is possible.
P.S. found here linux/bcm2710-rpi-3-b.dts at rpi-4.4.y · raspberrypi/linux · GitHub that bcm2710-rpi-3-b.dts file includes necessary information.
i2s_pins: i2s {
brcm,pins = <18 19 20 21>;
but I cant find the same fine in among Volumio’s files.
Please help…
