DSP C6674 holding i2c bus after DSP booting completes from I2C EEPROM

Hi Sir,


My custom board uses a DSP C6674 and MicroBlaze processor, both processors interfaced with a shared I2C bus connected with multiple I2C devices like EEPROM, Temperature sensor and current monitor sensors.

DSP is enabled to boot from I2C EEPROM successfully. But after that other I2C devices are not accessible from DSP as well as other MicroBlaze processor.

When DSP and its EEPROM isolated from main I2C bus, MicroBlaze processor is able to access other I2C devices even after DSP booting successfully.

Can somebody help on this, how other I2C devices are accessing after removing DSP from shared I2C bus.


Thanks!

Mani Kumar
