[U-Boot-Users] MX31ADS: I2C1 bus

Hi Sascha,

I downloaded current u-boot repo to perform a simple test on MX31ADS: I just have to verify that an I2C component connected to JP13 is detected by U-Boot (iprobe). So I enabled the I2C support in MX31ADS config file:

/* I2C */ #define CONFIG_HARD_I2C 1 #define CONFIG_I2C_MXC 1 #define CFG_I2C_MX31_PORT1 1 #define CFG_I2C_SPEED 100000 #define CFG_I2C_SLAVE 0xfe

U-Boot builds and boots fine however, when issuing iprobe command, SDA and SCL lines are stuck at ~2.1V. JP6 and JP7 are both in 2-3 position.

Am I missing something?

TIA, llandre
