K64F Fails to read I2C EEPROM

[mmahadevan108]

Where is this EEPROM chip located. I could not find it on the application shield board shown below:

I realized I don't have a test-shield board, can you please try the attached patch.

@mmahadevan108 , if you're a partner please reach out to your partner enablement contact and they will send you a couple boards)

Thanks, I have contacted them.

@mmahadevan108 I tried the patch, seems like an additional tweak is needed. With the patch the start condition isn't followed up by anything. Please give it a try on the test shield and let us know.

@maclobdell If you can retest latest master , there's a fix , I got all OK for i2c tests, using K64F target

I tested it with the master branch and confirm that everything passes now. @mmahadevan108 Thanks for the fix!
