Hi, I'm trying to store the u-boot environment in an EEPROM (at24c128) on a custom at91rm9200 based board. This fails when using the included HARD_I2C driver, and since there are known problems with the I2C controller on this uC, I'm trying to set up SOFT_I2C instead, without success so far...
Problem solved! Turns out the peripheral clock for the pio controller wasn't enabled. In the Linux code I looked at this was already done elsewhere. Thanks to Joakim and Matteo for valuable help. For the record, here is the code:
Did you try my patch also and did it work?
