All, in my current system the I2C bus is not working properly on a MPC8343 in u-boot v1.3.2.
i2c board config includes : #define CONFIG_HARD_I2C #undef CONFIG_SOFT_I2C #define CONFIG_FSL_I2C #define CONFIG_I2C_MULTI_BUS #define CONFIG_I2C_CMD_TREE #define CFG_I2C_OFFSET 0x3000 #define CFG_I2C2_OFFSET 0x3100 #define CFG_I2C_SPEED 100000 #define CFG_I2C_SLAVE 0x7F chip probing works fine. mvBL-M7> i2c probe Valid chip addresses: 30 48 50 68 reading the Chips gives all "ff" mvBL-M7> i2c md 50 0 10 0000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ Observing the I2C bus wires show that everything _works excellent_ : 100kHz speed as well as all data seems ok - but u-boot shows "ff". BTW: Fetching HRCW from I2C is also working fine. After some tries (i2c md ..) the bus hangs and no more transactions can be seen on the bus. regards, Andre Schwarz Matrix Vision MATRIX VISION GmbH, Talstraße 16, DE-71570 Oppenweiler - Registergericht: Amtsgericht Stuttgart, HRB 271090 Geschäftsführer: Gerhard Thullner, Werner Armingeon, Uwe Furtner ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
