 === Setup === === Setup ===
 +First we need to fetch a working cross-compiler. RetroBSD supports this one in Linux.
 +
 <code> <code>
 cd /usr/local cd /usr/local
Line 14: Line 18:
  
 === Checkout === === Checkout ===
 +Now we fetch the RetroBSD source from GitHUB. 
 <code> <code>
 mkdir -p /embedded mkdir -p /embedded
Line 20: Line 25:
 cd retrobsd cd retrobsd
 </code> </code>
-=== Build ===+=== Configure === 
 +In this example we will configure RetroBSD for the [[:boards:sdxl|SDXL]] board. 
 + 
 +First select the SDXL.
 <code> <code>
 sed -i 's/(MAX32)/(SDXL)/' Makefile sed -i 's/(MAX32)/(SDXL)/' Makefile
 +</code>
 +
 +Now we will enable two UARTS. Edit the following file,
 +<code>
 +vi sys/pic32/sdxl/Makefile
 +</code>
 +
 +and add the following within the DEFS section, save the file.
 +<code>
 +DEFS += -DUART1_BAUD=115200
 +DEFS += -DUART1_ENABLED=YES
 +DEFS += -DUART2_BAUD=115200
 +DEFS += -DUART2_ENABLED=YES
 +</code>
 +
 +Now edit the kernel configuration to enable the devices.
 +<code>
 +vi sys/pic32/sdxl/SDXL
 +</code>
 +
 +Add the following options to enable the UARTS.
 +<code>
 +# tty0
 +device uart1 baud=115200
 +# tty1
 +device uart2 baud=115200
 +</code>
 +
 +
 +=== Build ===
 +Building will create the unix boot image and the SD card image for the system.
 +<code>
 make cleanall make cleanall
 make make
 +</code>
 +
 +=== Install ===
 +
 +First we create the file system image on a micro SD card.
 +<code>
 +dd if=sdcard.img of=/dev/sdc bs=4M
 +</code>
 +
 +Next, Hold the PROG button and toggle RESET on the SDXL board to enter the boot laoder. We will use [[:tools:pic32prog|PIC32Prog]] to install the kernel.
 +
 +<code>
 +pic32prog -d /dev/ttyACM0 ./sys/pic32/sdxl/unix.hex

 +
 +=== Login ===
 +
 +A virtual com port should have been detected after installation.
 +
 +The kernel will log something similar to the following.
 +<code>
 +usb 1-1.4: new full-speed USB device number 12 using dwc_otg
 +usb 1-1.4: New USB device found, idVendor=04d8, idProduct=000a

 +cdc_acm 1-1.4:1.0: This device cannot do calls on its own. It is not a modem.
 +cdc_acm 1-1.4:1.0: ttyACM0: USB ACM device
 +</code>
 +
 +Connecting with a terminal emulator to the virtual com port and pressing enter will boot the system.
 +<code>
 +screen /dev/ttyACM0 115200

 +
 +Enter the username root with an empty password to login.
