This processor is having silicon revision 1.0. We have RTC & ADC connected over i2c1. Also, We are using GPIO pins muxed with i2c2 in GPIO mode. The problem is, when i configure these muxed gpio pins in GPIO mode, my ADC & RTC is not working. Content of SICRL & SICRH Register at this Condition were as follows :- SICRL : 33fc0800 SICRH : 0030c003 We disabled GPIO mode for GPIO pins muxed with i2c2 and found ADC & RTC over I2C1 working fine. Content of SICRL & SICRH Register at this Condition were as follows :- SICRL :- 33fc0800 SICRH :- 0000c003 Thanks Rudresh -- View this message in context: http://www.nabble.com/I2C1-is-not-working-in-U-boot%2C-When-I2C2-pins-are-config-as-GPIO-in-MPC8313-board-tp22620921p22620921.html Sent from the Uboot - Users mailing list archive at Nabble.com.
