Hi Robert, Jason and William, Sorry for not pulling the device tree files, I've been out of town. I hope the files help someone in the future if they purchase a mikroBus cape.
This morning I found that the mikroBus cape is using a Microchip 24AA01 (1K, 128 x 8) eeprom not a 24C256. Two questions came to mind after I found this out. 1.) The Microchip 24AA01 doesn't use A0 ~ A2 (Don't Care). Responds to any 0x5X address. Potential cape addressing conflicts here. 2.) The non-B version clock is limited to 100Khz. Is the default clock for i2c bus 1 > 100khz? Ex. 400Khz 1000Khz? Can I force it to 100 Khz? Yep, having problems writing to the eeprom. The schematics don't agree with the delivered board. Looks like they intended to use the 24C256 but in manufacturing they used the 24AA01 instead. Mike On Monday, July 27, 2015 at 10:27:54 AM UTC-7, RobertCNelson wrote: > > Thanks!
