Hi, I’m trying to configure the other I2C pins of the BBAI, but I tried all the codes on the internet and it didn’t work. Can someone explain to me how I can activate the other I2C devices, please?
What image are you running?
uname -r?
Regards,
debian@beaglebone:~$ uname -r
4.19.94-ti-r73
I need to activate the I2C device for 17 and 18 pins
This should work, In /boot/uEnv.txt, add:
uboot_overlay_addr4=BONE-I2C1.dtbo
if it doesn’t, please install:
sudo apt update ; sudo apt install bb-beagle-version
and then run:
sudo beagle-version
So we can debug it…
Regards,
I tried the first one adding this to the code and it did not work,
uboot_overlay_addr4=BONE-I2C1.dtbo
uboot_overlay_addr5=BONE-I2C2.dtbo
and then i did the second part but when i scan the i2c devices and could not see the new device, i see the same thing,
debian@beaglebone:~$ i2cdetect -r 1
Error: Could not open file /dev/i2c-1' or /dev/i2c/1’: No such file or directory
debian@beaglebone:~$ i2cdetect -r 2

do you thing that I am doing something wrong?
Best,
Please share the output of:

Otherwise i can’t help you…

You’ve already enabled BONE-CAN0/BONE-CAN1 in /boot/uEnv.txt, you need to also enable
BONE-I2C1.dtbo and BONE-I2C2.dtbo
Post your /boot/uEnv.txt
Regards,
and How can I enable these two?
Best,
And this is what I have in the uEnv.txt file:
#Docs: Beagleboard:U-boot partitioning layout 2.0 - eLinux.org

#uuid=

#In the event of edid real failures, uncomment this next line:
#cmdline=coherent_pool=1M net.ifnames=0 rng_core.default_quality=100 quiet video=HDMI-A-1:1024x768@60e
##enable Generic eMMC Flasher:
#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3-no-eeprom.sh

uboot_overlay_addr5=BONE-I2C2.dtbo
#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh
You’ve defined the uboot_overlay_addr4 and uboot_overlay_addr5 variables twice…
I’d do:
uboot_overlay_addr4=BONE-CAN0.dtbo
uboot_overlay_addr5=BONE-CAN1.dtbo
uboot_overlay_addr6=BONE-I2C1.dtbo
uboot_overlay_addr7=BONE-I2C2.dtbo
make sure u-boot is up-to date…
sudo apt update ; sudo apt install bb-u-boot-am57xx-evm
sudo /opt/u-boot/bb-u-boot-am57xx-evm/install-mmcblk1.sh
Regards,
Thank you for your help, it works.
Best,
