Hi,
I m Aravind. I am using DSP processor TMS320VC5502. I have written a code for
receiving data from PC using UART module. I am now booting DSP from external I2C
EEPROM. Can i get data from the same I2C EEPROM from a specified location using
the I2C module of the DSP after the booting process is complete.
Regards
Aravind.

If DSP is master and EEPROM is slave, then yes it should be possible. You will need
a) a data sheet for the EEPROM device and b) some example C55x I2C code. In C55x
code you should be able to use CSL functions for I2C:
