Hi to everybody,
i designed the device based on AM1806 processor. Device consist of AM1806 TI Sitara processor, 128MB of mDDR RAM, 8MB NOR Flash for booting, uSD/MMC card slot, OTG USB Port, and Aptina MT9P031 CCD sensor. Whole board is powered by TPS65070 PMIC from TI. The board is designed to be powered from DC adapter, USB port or battery.
I designed board to can be bootable from SD/MMC card, UART2 port, SPI Flash and Emulation debug. Booting method which will be used can be selected with DIP switches.
Board is assembled and it is powered for the first time. I got correct voltage ranges on TPS65070 regulated output pins. Also the current is 20mA, and I assumed that that is correct.
Now I have to boot Linux and write application software, and that is the reason why I writing the post here. I'm hardware engineer and this is my first time to doing something like this.
Can somebody explain to me what is next step to keep alive the device that I made. I read that I need to use pinmux utility to configure hardware. Does somebody make the device from the beginning and which are the steps?
Thanks for answers.
