There is a doubt I have ever since I started working on the microzed and breakout carrier card.
There is a VCCIO jumper on the carrier card which provides 3 options: 1.8V, 2.5V and 3.3V. The following pins on carrier card are supposed to give out a voltage level (DC signal) as selected by the VCCIO jumper:
In order to check that the carrier card along with the VCCIO jumper are working fine, we should check the level of the above mentioned pins.
Well in my case, the above mentioned pins have a voltage level of 0.6V when I set the jumper to 1.8V position. These pins maintain the same voltage level even when I switch the jumper to 2.5V or 3.3V. Could anyone please suggest what might be the issue here? I feel that the carrier card has some problem. Should I get a new carrier card?
I am facing serious issues as all the output signals from CON1 and CON2 pins which are controlled by the VCCIO jumper are attenuated to below 0.5V. Please suggest if I should buy a new card.
