PICO-TGU4 how to update bios?

fred — Fri, 29 Apr 2022 06:31:12 +0000

Hi!

I have a PICO-TGU4 board and i need to update the bios, so i created a usb key as described here https://forum.aaeon-community.com/discussion/39/update-bios-through-uefi-shell

but I doesn't work, it will not boot the uefi shell from the key and always come back to the bios settings...

But the key is recognized as uefi
What am i missing ? Thank you.

How to do HW modification to support I2C on PICO-APL1

Han — Mon, 26 Aug 2019 15:08:46 +0000

here we discuss about HW modification to support I2C on PICO-APL1.
(Note : any damage from H/W change at customer could violet warranty.)

PICO-APL1 A1.0 LPC connector CN18, pin 10/11 are co-lay for SMBUS and I2C , default is SMBUS.
schematic info as following:

If customer needs I2C, it needs following rework, please check detail in picture.
1.R437 change to R481
2.R440 change to R482
They are all 0 ohm resister. 1050700004 (TF)CR.0.1/16W.5%.0402.SMD

Hi-safe V3 API all I2c Ids results in EAPI_STATUS_UNSUPPORTED

PeterHer007 — Sat, 12 Feb 2022 09:28:56 +0000

Hi All,

I am trying to use the EApiI2CGetBusCap function from the API, but every I2c Id (see below) results in EAPI_STATUS_UNSUPPORTED.

Functions for GPIO are working fine.

I have : PICO-APL1-A10-0001

Any ideas?
Thanks in advance.

Audio Line-out

Han — Wed, 18 Sep 2019 13:59:06 +0000

PICO-APL1 has connector (CN17) for line-out .
line-out signal is from Realtek Codec ALC892 Chip (pin 35 Front-L and pin 36 Front-R ) .
it is front channel output signal and can't be connected to speaker directly, it needs still amplifier.

current from SATA power connector CN2

Han — Mon, 26 Aug 2019 15:08:22 +0000

the rating current of pin in CN2 is 2A, below is Connector Spec /Schematic info.

Update BIOS through UEFI Shell

Han — Mon, 20 May 2019 11:56:45 +0000

PICO-APL1 BIOS files include update tool and BIOS image (.bin) in a ZIP file.
for example standard v1.3 ZAP1AM13

it can update the BIOS per UEFI as followings
1. unzip the files and copy to a USB disc.
2. Power on board with USB drive attached.
3. select the first boot priority to UEFI Shell.
4. Move operating directory to USB drive (fs0 or other labels)
SHELL> fs0:
5. Enter the directory with BIOS file and update batch
6. Execute update batch (go.nsh)
7. Confirm update procedure is completed without problem
8. Reboot system (automatically)

an UEFI-Shell screen for reference.

Wake-up On Lan

Han — Mon, 05 Aug 2019 12:28:26 +0000

for PICO-APL1, WOL function is support in general.
the OS/ Driver will also play a part for WOL function in application, please make sure they are configured by using this function.

In this discussion, it will show some LVDS cable solultions for certain panels.

Windows IoT Core drivers

Han — Wed, 15 May 2019 14:04:07 +0000

Intel BSP link as below for building IoT Core image for PICO-APL1.
https://downloadcenter.intel.com/download/25618 <- Please use the x64 version for Apollo lake

For the serial port driver (HS-UART), man can find the serial port driver in IoT Core BSP and it's provided by Microsoft
this link: https://docs.microsoft.com/en-us/windows-hardware/manufacture/iot/bsphardware#intel-bsps

BTW: AAEON has made a test version for Win10 IoT Core v1703 for PICO-APL1, follow the link below.

PICO-APL1 LVDS BIOS setting for panel resolution/ channel / color depth.

Han — Mon, 13 May 2019 13:06:14 +0000

There are panel resolution and color depth settings for LVDS interface in the BIOS of PICO-APL1 for different compatible displays that may appear in the application.

Panel type sets the resolution of the target display

Color depth sets the LVDS channel and color of the target display

Further explanation is provided here to avoid misunderstanding
Color depth
18bit= single channel & 6 bit color
24bit= single channel & 8 bit color
32bit= dual channel & 6 bit color
48bit= dual channel & 8 bit color

For example, the pictures above selected setting for 1024x768 panel with a single channel 6 bit color .

note:
Resolution from 1440 x 900 to 1920x1200 must be dual channel data transmission
So choose 18/24 Bit (Single channel) can't light the screen.

PICO-APL1 onboard LEDs and optional external LED

Han — Wed, 08 May 2019 16:09:33 +0000

There are 3 LED indicators on the PICO-APL1 board.
Red LED indicates standby voltage ready
Green LED indicates operating voltage ready
Blue LED is the hard disk indicator

In addition to the LEDs on the board, the PICO-APL1 can connect external LED via front panel CN3.

(Info from PICO-APL1 Manual)

Here is schematic of CN3
HDD_LED signal (pin 3 and 4)
PWR_LED signal (pin 7 and 8)
Both are an voltage 3.3V with 330 Ohm resistor , it pull maximal 0.01A current.

PICO-APL1 Thermal Report and Temperature Montior

Han — Wed, 08 May 2019 13:28:33 +0000

PICO-APL has operating temperature 0~60 °C
below link is one thermal report based on intel N4200 CPU with 8GB RAM under windows 10 with PassMark Burn in Test 8.1 Pro.
It shows thermal image and measure key component temperature.
https://www.dropbox.com/s/qnwe8bbg4d3rg60/PICOAPL1THR.pdf?dl=0
(PICOAPL1THR.pdf)

AAEON also provides HW Monitor function in Hi-safe SDK under windows .
Please check Hi-safe info under AAEON homepage
https://www.aaeon.com/en/ac/aaeon-hi-safe

There are CPU/Chipset/system temperature in BIOS and HW Monitor from Hi-safe.

They link to 3 thermal sensors on board.
One close to CPU (CPU)
One close the south bridge (Chipset)
One is inside of the Super IO Chip (System)

Switch COM2 RI/5V/12V

Han — Mon, 29 Apr 2019 12:31:34 +0000

PICO-APL1 COM2 support switch RI/+5V/+12V. (CN17 pin 8 , Ring in default )

PICO-APL1 has BOM selection to switch RI/5V/12V for COM2 per 0 Ohm resistors R256/R248/R250.
In default is only R248 assembled on board (RI in default).

So if it needs switch to 12V or 5V, it could do followings
1# From RI to 12V -> Remove R248 and add R256
2# From RI to 5V -> Remove R248 and add R250
Below is location of the resistors on board for reference (close to LAN connector CN10)

Note: for reworking by self it could violate the warranty when damage caused.
