I have designed a peripheral board for colibri vf61. I am providing 3.3V to the card but its not booting. Same card work in development board. Is there any pull up or pull down to be given for booting colibri vf61.
There are several things which could prevent a module from booting, including wrong reset signals. Did you check the serial debug output on your carrier board? Maybe it starts booting but gets stuck somewhere? Please compare our carrier board design reference documents and compare them with your schematic. We have several documents which could help:
- Viola Carrier Board design (very simple design, so it’s closer to the minimum requirements than e.g. the bigger Colibri Evaluation Board schematic: http://developer.toradex.com/carrier-board-design/reference-designs
- Design Guides, especially the Colibri Carrier Board Design guide is helpful: http://developer.toradex.com/carrier-board-design/carrier-board-design-guides
I hope this leads you to the solution.
