LAUNCHXL-F28377S: I2C EEPROM Example Code on the LaunchXL working?

Brenden Fung

Part Number: LAUNCHXL-F28377S

Hello TI community,

I am having troubles getting the I2C EEPROM example code to work on the LaunchXL-F28377S. I realized early on that the GPIO pin mux code had to be changed to fit the PZP configuration of the F28377S. I also believe there is an EEPROM module on the LaunchXL as an EEPROM module appears on the overview schematic.

I am not sure which pin I am suppose to set using the GPIO_SetupPinMux function provided to operate the EEPROM. I was wondering if anyone was able to get the message to transfer correctly into the I2cMsgIn1 message buffer array.

Brenden,

There is not a an EEPROM that is accessible by the F28377S on this board. The EEPROM on the board is storing the image for the FTDI chip. There is no connection to the MCU.

It does not look like there is any BoosterPack for an EEPROM available on http://www.ti.com/launchpad . One suggestion I have is to find an EEPROM board, and make a custom harness to connect to the LaunchPad headers. There are also some prototyping BoosterPacks for custom designs as well.

Does this help you out?

Hey Mark, thank you for the reply! This explanation definitely clears some stuff up for me. I think I will use your suggesting and see if I can rig something up. Thank you!

Glad I could clear that up for you. If you have additional questions when you get to the EEPROM coding. Please create a new post!
