Quelltext der Seite Linux BSP customization for Argos®2D A100 Camera

This document describes various specifics of the '''Argos&reg;<sup>2D</sup> A100 Camera''' as far as the '''Bluetechnix MX53 Linux Board Support Package''' is concerned.

= Quick start =

Here is how to start with your Argos&reg;<sup>2D</sup> A100 Camera based on the CM-i.MX53 SoM.

*Usually the camera will arrive pre-mounted
*Configure the DIP switches on the base board for [[#SD (Secure Digital) card|SD card boot]]. (If you do not want to boot the Argos&reg;<sup>2D</sup> A100 demo application, boot Linux only from [[#SPI NOR flash|SPI-NOR]]).
*Connect 12V DC to the power connector on the back panel
*Connect a monitor or TV via HDMI on the back panel
*If you like, connect Ethernet on the back panel
*Optionally, connect to the serial terminal to see the board's boot messages (via eCAM-EXT-Debug board on the red extension connector X11)

= Boot modes =

The Argos&reg;<sup>2D</sup> A100 board allows to configure the CM-i.MX53  module's boot mode via a DIP switch.

== SPI NOR flash ==
{|
| width="150" | V1.0.X || width="150" | V1.1.X || width="150" | &ge;V1.2.X

|-
|}

== USB/UART boot mode ==
NOTE: The mfgtool requires this boot mode to be set.

|-
|}

= JTAG connector =

Some JTAG debuggers, like the PEEDI JTAG, short pins #1 and #2 (VREF and VSUPPLY) of the [https://www.jtagtest.com/pinouts/arm20 20-pin ARM JTAG header] (X9). On the Argos&reg;<sup>2D</sup> A100, these pins are connected to different voltages (2V8 vs. 3V3) and MUST NOT be shortened.

'''Important!''' If your JTAG device/connector shorts pins #1 and #2, the following switch setting must be done on Argos&reg;<sup>2D</sup> A100 &ge;V1.2.X. It disconnects 3V3 from JTAG pin #2 (VSUPPLY).
'''<span style="color:#cc0000">Do not connect such a JTAG device to Argos&reg;<sup>2D</sup> A100 &le;V1.1.X!</span>'''


{|
|  &ge;V1.2.X ||
|-
| {{dipswitch|X|X|X|0}} || Disconnect 3V3 from JTAG pin #2 (VSUPPLY)
|-
| {{dipswitch|X|X|X|1}} || Connect 3V3 to VSUPPLY
|-
|}

= U-Boot/Linux kernel configuration =

There is a Linux kernel parameter for the Argos&reg;<sup>2D</sup> A100 Camera which enables some specific features at boot time. Add this to your ''bootargs_base'' variable in U-Boot.

*Boot U-Boot
*Press any key to stop Linux kernel boot, you will get to U-Boot's prompt.
*Add the Linux kernel parameter:
 CM-i.MX53 U-Boot> setenv bootargs_base $(bootargs_base) <span style="color:#009900">board=icam</span>
 CM-i.MX53 U-Boot> printenv bootargs_base
 bootargs_base=setenv bootargs console=ttymxc0,115200 hdmi di1_primary video=mxcd
 i1fb:RGB24,1280x720M@60 console=tty1 <span style="color:#009900">board=icam</span>
 CM-i.MX53 U-Boot> 

What it does:
*Reads factory reset pin on boot and prints the message "Factory Reset on iCAM-CM-i.MX requested!" in case the button is pressed
*Configures on-board RTC correctly
*Doesn't switch off the PMIC after ''poweroff'' command (since restart would require power-cycling)

= Serial terminal over USB-OTG =
On the Argos&reg;<sup>2D</sup> A100, the UART1 serial port is only accessible on an extension connector via a breakout-cable. Alternatively, one may use a serial terminal over USB-OTG.

Please find the instructions in the [[Linux Software User Manual (i.MX53 Modules)#Serial terminal over USB|MX53 Linux Software User Manual]].
