Title: TE0720/TE0701 i2c interfaces
Post by: jhannon on April 10, 2014, 12:37:10 AM
Question 1:
We have a TE0720 SoM installed on the TE0701-03 carrier board. We also have a custom FMC card that we want to install on the TE0701 but it requires 2.5V VADJ only. The TE0701 always comes up with the power enable to the FMC (EN_FMC = 1) and with FMC VADJ at 3.3V whether an FMC board is installed or not.  According to the Trenz documentation FMC power should be disabled by default. Any idea why the board is behaving like that?

Question 2:
Ultimately we will not run u-boot or linux. So now I am running a standalone application developed in C within SDK. If I am not running the Trenz u-boot/linux installation am I missing any required configuration of the TE0720 CPLD?
