Device Notes +================================ +a. Serial Port +-------------- +The FRI2 has an optional serial daughter card providing a serial +console via the micro-USB port on the top of the device adjascent the +SIM card slot. + +The UART from the EG20T is connected to a TI UART-to-USB device +(TUSB3410) which appears as a serial port on the host computer. From a +Linux host, load the driver with the following options: + +# modprobe ti_usb_3410_5052 vendor_3410=0x0451 product_3410=0x5053 + +In future versions of the Linux kernel (3.4 and later), the +vendor and product codes are detected automatically. + +When you power on your FRI2, your host will discover a serial device +and name it /dev/ttyUSB0 (or similar). You can communicate with this +device at 115200 8N1 using your preferred terminal emulator. + +In order to redirect the BIOS console to the serial port, you may need +to set up console redirection in the BIOS menu. The serial port is +referred to as COM2 in the BIOS. + + Advanced + Serial Port Console Redirection + COM2 + Console Redirection [Enabled] + Console Redirection Settings + Terminal Type [ANSI] + Bits per second [115200] + Data Bits [8] + Parity [None] + Stop Bits [1] + Flow Control [None] + Recorder Mode [Disabled] + Resolution 100x31 [Disabled] + Legacy OS Redirection [80x24] + +Note that the UART clock is configured at 48MHz in the firmware. This +will cause problems with software assuming a typical 1.8 MHz clock. +The Linux kernel pch-uart driver is aware of the clock, but Syslinux, +for example, is not. For software expecting a typical clock, directing +them to use a BAUD of 3318 (rather than 115200) can work around the +problem. + +b. HDMI +------- +The FRI2 has two micro HDMI ports. The one closest to the 1/8" audio +jacks is the primary display. + +c. Power Reset +-------------- +The recessed button adjacent the LEDs on the top of the device is a +power reset button. + +d. Accelerometer +---------------- +The LIS331DLH accelerometer is connected to the I2C bus on the CPLD on +the compute module. The driver for this chip is under active +development and will be included in the BSP once completed. + +e. GPIO +------- +The FRI2 has two I2C PCA555x GPIO devices used for internal control +signals. These have not been exposed in the current release of the +BSP, but may be in the future. Regardless, these do would not provide +general purpose IO with which to read or drive additional signals. + +f. MMC +------ +The FRI2 provides two microSD card MMC devices. One is located +adjacent the 1/8" audio jacks, another is located on the board inside +the chassis. These devices can be used to boot the device, or as +secondary storage. + +g. 802.11 +--------- +The Intel Corporation Centrino Advanced-N 6205 that ships with the +FRI2 is supported. You can use connman-gnome to configures the +interface. + +h. 802.15.4 +----------- +The TI CC2531 802.15.4 radio is a USB ACM modem. The MAC is enabled by +issuing the following command: + +# echo J > /dev/ttyACM0 + +The bank of 3 LEDs nearest the power reset button will change if this +command is executed successfully. If you have a 3G modem installed, +the 802.15.4 device may appear as /dev/ttyACM3 instead. + +No further testing or integration has been done. + +i. Audio +-------------------- +The FRI2 has an 1/8" analog output (nearest the antennae), a line-in +input below that, as well as SPDIF over HDMI. These can be tested +using the alsa-utils package. aplay -l will list both playback +devices: + +# aplay -l +**** List of PLAYBACK Hardware Devices **** +card 0: MID [HDA Intel MID], device 0: ALC262 Analog [ALC262 Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 +card 0: MID [HDA Intel MID], device 3: ALC262 Digital [ALC262 Digital] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + +Using a sample WAV file, you can use aplay to play to either device: + +Over analog: +# aplay -D plughw:0,0 sample.wav + +Over HDMI: +# aplay -D plughw:0,3 sample.wav + + +j. Optional Devices +------------------- +The FRI2 has two mini-PCIe slots internally. The device ships with a +half-length wireless card installed. This can be replaced with a +wireless + bluetooth card. The other slot is available for use with +cellular cards or mSATA SSDs. + +The Ericsson F5521gw 3G modem has been verifed with the FRI2 images. +Note that the connman-gnome UI does not allow for configuring the +cellular interface. The ofono-tests package can be used to configure +the modem and bring up an interface. + + +IV. Known Issues +---------------- +a. EFI +------ +The FRI2 firmware can boot to an EFI shell. It does not yet boot the +EFI payload provided on the FRI2 live image. This is a known issue +under investigation. + +b. Client USB is disabled +------------------------- +The micro-USB port adjacent the primary HDMI port is intended for +Client USB functionality, but is not supported on current revisions of +the device. + +c. Audio over secondary HDMI port only +-------------------------------------- +While audio over HDMI has been shown to work, it seems to only work over +the secondary (bottom-most) HDMI port. There does not appear to be a +deterministic way of getting the device to output the signal (video and audio) +over the secondary port. |
