Hi, I am trying to use Adafruit ChronoDot 3.0 for an RTC on the BB AI64. This uses a max 31328, which is functionally equivalent to a DS3231. I was successful (I think) in installing I2C2 on the BB AI64 with the max31328 attached. (One strange thing was that I could not see the max31328 using i2cdetect -y -r 2. I then ran ls -l /dev/bone/I2c and saw that 2 → …/…/i2c-5. When I ran i2cdetect -y -r 5 I saw that 68 was attached? I then got stuck in creating /dev/rtc?
I found Robert’s discussion on this issue on the forum:
src/arm/overlays/BB-I2C1-RTC-DS3231.dts · v5.10.x-ti-unified · BeagleBoard.org…
I pulled these then make & make install and copied the 2 dtbo files into extlinux.conf. The BB AI64 now fails to boot. I’m in the process of reinstalling Debian 11. Any help would be greatly appreciated. Thanx
