Hi,
I am using AM1808. We are following LogicPD hardware documents.
We are customizing our new board based on LogicPD schematics. In our application we are using below peripherals. Also some of the features are not enabled in our design.
Enabled Peripherals:
- AM1808 Processor
- Crystal
Clocks
- AM1808(24 kHz), RTC( 32.768 kHz) crystal
- Memory:
- Mobile DDR
- SPI Flash - 8 MB SPI flash chip for booting
- Ethernet
(10/100) PHY:
- Ethernet is used for networking interface (TFTP/NFS).
- LCD
Display Interface:
- 5inch TFT (480x272) LCD
- Serial
Interfaces:
- UART0 - SPI
- UART1 - GPS
- UART2 - Host(PC) ttySx RS232 serial Debug
- SPI1 - FLASH boot the AM1808.
- SPI0 - This port control/configure for other ICs.
- I2C0/1 - This is used to control/configure many ICs.
- USB
Interface
- USB 1.1 full-speed host port
- USB 2.0 OTG port
- SD card
- Touch Interface
- General Purpose I/O (GPIO)
- JTAG Debugger Interface
- Power Management
- Boot mode / FET mux DIP switches (S7)
Not Enabled Peripherals:
- Audio Codec
- Battery Management circuit.
- SATA
- EMIF(External memory interface)
- Video port interface (VPIF) connector.
- Some General Purpose I/O (GPIO)
- Expansion/Feature Option.
- stereo jacks
What are the precautions will take care in kernel drivers. If we are not using some of the gpio/audio is it necessary to change any default settings for gpio/audio.
Anyone can suggest we can use same bootloader and kernel.
Regards
Francis
