We are using MPC885ADS Eval. board ,we are porting U-Boot 1.1.1 on it and working fine,
I understand that you rae using the CPM implementation of the driver?
You are aware of the differences between MPC885 and other (older) processors of the MPC8xx family (like MPC860), aren't you? Did you modify the I2C driver accordingly (especially the handling of the iic_rpbase filed in the parameter RAM) ?
We are connected an EEPROM (CHIP ADDRESS : 0X50) on I2C bus, when we trying to check with "iprobe" command its displaying a message like :
Valid chip addresses: 00 01 02 03 04 05 06 07 ............ 80
Is it really displaying exactly such a row of dots ?
Its talking a lots of time and not working.
It's normal that the ip[robe command takes very long with the CPM implementation; is there any good reason for not using soft-I2C?
Has anyone faced same problem?
Did you search the mailing list archive?
