CCS/TMS320F28335: the read and write of eeprom by 28335

Tool/software: Code Composer Studio

hi,I recently made a circuit board, when i use f28335 to read data from eeprom , the results are all FF, I guess the reason is there is no data inside the eeprom ; now I use 28335 to write some datas to the EEPROM , and save to the I2caRegs. I2CDXR, I can guarantee it is correct; then i want to read data from eeprom to 28335, but i find that the datas are still all FF, how this is going on? when i save the data to I2caRegs.I2CDXR,does it mean that i have saved that data to eeprom? Thank you very much

Ding,

Did you make sure to follow the format expected by EEPROM DS to write into EEPROM?

I would also probe the I2C signals to make sure my program is sending data is correct format to initiate EEPROM write.

Manoj
