J721EXSOMXEVM: J721EXSOMG01EVM

Sergiu Berinde

Part Number: J721EXSOMXEVM

We are using the GPIO LedBlink example from the pdk_jacinto_07_03_00_29 with no modifications, built for MCU1_0.

We see in the terminal window of CCS that "All tests have passed", however none of the USER LEDs is showing any activity...

SDK used is 07 03 00 07

Please advise what could be the issue.

Thank you!

    Hi Sergiu,

    There are no GPIO LEDs available on the J721E EVM board, the GPIO LedBlink example is just to verify the GPIO functionality. If you want to validate the LEDs, which are connected to I2C IO expander, you can use LED diagnostic example.
