I'm using an APU2C2 board to communicate with 1-Wire devices through the I2C bus (Through a DS2492 chip).
The communication appears to be very slow
I used the exact same devices with an ALIX2D without any issues.
Under Linux, I've noticed that the i2c scanning utility "i2cdetect" is also much slower when runned under APU than ALIX.
It seems that the I2C bus can be operated at different speed, I don't know if it's related to the chips used or whatever, but it's really a big issue for me.
Any ideas, comments, solutions, workarounds ?
