Hi All
We are working on DM3730 based custom board on which we want to access a passive device (which is having no registers) through I2C interface , at u-boot level.
At kernel level we are able to perform write and read operations using i2c_master_send and i2c_master_recv function calls respectively .
At u-boot level we tried to access the device through i2c_read_byte and i2c_write_byte function calls , but both requires a specific register address to perform read and write operations
We have by passed the register address in i2c_write_byte function , after which write is successful. But We are not able to read the correct values through read function .
Please tell us how can we perform read and write operations for such a device .
Is there any other function calls present in u-boot which doesn't utilize slave's registers.
Thanks
Harsh
