163III. Device Notes
164================================
165a. Serial Port
166--------------
167The FRI2 has an optional serial daughter card providing a serial
168console via the micro-USB port on the top of the device adjascent the
169SIM card slot.
170
171The UART from the EG20T is connected to a TI UART-to-USB device
172(TUSB3410) which appears as a serial port on the host computer. From a
173Linux host, load the driver with the following options:
174
175# modprobe ti_usb_3410_5052 vendor_3410=0x0451 product_3410=0x5053
176
177In future versions of the Linux kernel (3.4 and later), the
178vendor and product codes are detected automatically.
179
180When you power on your FRI2, your host will discover a serial device
181and name it /dev/ttyUSB0 (or similar). You can communicate with this
182device at 115200 8N1 using your preferred terminal emulator.
183
184In order to redirect the BIOS console to the serial port, you may need
185to set up console redirection in the BIOS menu. The serial port is
186referred to as COM2 in the BIOS.

202
203Note that the UART clock is configured at 48MHz in the firmware. This
204will cause problems with software assuming a typical 1.8 MHz clock.
205The Linux kernel pch-uart driver is aware of the clock, but Syslinux,
206for example, is not. For software expecting a typical clock, directing
207them to use a BAUD of 3318 (rather than 115200) can work around the
208problem.
209
210b. HDMI
211-------
212The FRI2 has two micro HDMI ports. The one closest to the 1/8" audio
213jacks is the primary display.
214
215c. Power Reset
216--------------
217The recessed button adjacent the LEDs on the top of the device is a
218power reset button.
219
220d. Accelerometer
221----------------
222The LIS331DLH accelerometer is connected to the I2C bus on the CPLD on
223the compute module. The driver for this chip is under active
224development and will be included in the BSP once completed.
225
226e. GPIO
227-------
228The FRI2 has two I2C PCA555x GPIO devices used for internal control
229signals. These have not been exposed in the current release of the
230BSP, but may be in the future. Regardless, these do would not provide
231general purpose IO with which to read or drive additional signals.
232
233f. MMC
234------
235The FRI2 provides two microSD card MMC devices. One is located
236adjacent the 1/8" audio jacks, another is located on the board inside
237the chassis. These devices can be used to boot the device, or as
238secondary storage.
239
240g. 802.11
241---------
242The Intel Corporation Centrino Advanced-N 6205 that ships with the
243FRI2 is supported. You can use connman-gnome to configures the
244interface.
245
246h. 802.15.4
247-----------
248The TI CC2531 802.15.4 radio is a USB ACM modem. The MAC is enabled by
249issuing the following command:
250
251# echo J > /dev/ttyACM0
252
253The bank of 3 LEDs nearest the power reset button will change if this
254command is executed successfully. If you have a 3G modem installed,
255the 802.15.4 device may appear as /dev/ttyACM3 instead.
256
257No further testing or integration has been done.
258
259i. Audio
260--------------------
261The FRI2 has an 1/8" analog output (nearest the antennae), a line-in
262input below that, as well as SPDIF over HDMI. These can be tested
263using the alsa-utils package. aplay -l will list both playback
264devices:
265
266# aplay -l

281# aplay -D plughw:0,3 sample.wav
282
283
284j. Optional Devices
285-------------------
286The FRI2 has two mini-PCIe slots internally. The device ships with a
287half-length wireless card installed. This can be replaced with a
288wireless + bluetooth card. The other slot is available for use with
289cellular cards or mSATA SSDs.
290
291The Ericsson F5521gw 3G modem has been verifed with the FRI2 images.
292Note that the connman-gnome UI does not allow for configuring the
293cellular interface. The ofono-tests package can be used to configure
294the modem and bring up an interface.
295
296
297IV. Known Issues
298----------------
299a. EFI
300------
301The FRI2 firmware can boot to an EFI shell. It does not yet boot the
302EFI payload provided on the FRI2 live image. This is a known issue
303under investigation.
304
305b. Client USB is disabled
306-------------------------
307The micro-USB port adjacent the primary HDMI port is intended for
308Client USB functionality, but is not supported on current revisions of
309the device.
310
311c. Audio over secondary HDMI port only
312--------------------------------------
313While audio over HDMI has been shown to work, it seems to only work over
314the secondary (bottom-most) HDMI port. There does not appear to be a
315deterministic way of getting the device to output the signal (video and audio)
316over the secondary port.
