[beagleboard] Re: Does not detect RTC (ds1307)

The kernel driver isn't seeing the RTC. If it did, it would have claimed the I2C address and there would be "UU" in it's place instead of the address. You're either missing the correct kernel driver for your RTC or the device tree isn't set up for this scenario. I don't use any RTC parts so

This is the screen when I connect a new beaglebone green with an rtc. If I burn the latest image, the beaglebone does not detect the rtc. El jueves,

Also, I saw something really weird on my board with an uninitialized RTC: On one of my boards with an uninitialized RTC, the RTC kernel message ("hctosys: unable to read the hardware clock") went away when I "hot plugged" a USB<->serial converter into one of our USB ports on our board. The

I'm working with the RTC (MCP794110) at the moment, but on a "BB-X15 - like" custom board platform. I'm not sure I follow. your post.. What's the I2C tool? Are you talking about attaching the RTC to the BBB via the I2C tool or a problem with reading the RTC on the BBB? Pardon my ignorance but
