barish Posted February 7, 2019 Share Posted February 7, 2019 I did the following upgrades this morning libcurl3:armhf (7.52.1-5+deb9u8, 7.52.1-5+deb9u9), libgd3:armhf (2.2.4-2+deb9u3, 2.2.4-2+deb9u4), armbian-config:armhf (5.72, 5.74), linux-headers-next-sunxi:armhf (5.70, 5.73), linux-image-next-sunxi:armhf (5.70, 5.73), curl:armhf (7.52.1-5+deb9u8, 7.52.1-5+deb9u9), libcurl3-gnutls:armhf (7.52.1-5+deb9u8, 7.52.1-5+deb9u9), linux-dtb-next-sunxi:armhf (5.70, 5.73), base-files:armhf (9.9+deb9u6, 9.9+deb9u7) and found my I2C bus not working anymore. I did a scan on the 4 buses (Olinuxino Micro A20) and found a device on i2c-1 instead of i2c-0, changed my settings and all worked again, so I guess one of the updates must have changed the labeling of the busses? Is this by accident or on purpuse? Link to comment Share on other sites More sharing options...

This is indeed the case. Thanks for this information, the change must have crept in lately. If I had the energy I could find out which of the i2c adapters on the Olinuxino were labeled as "hdmi", but right now, since I don't need to know, I won't...
