RZ-A/Boards/YLCDRZA1H



=YLCDRZA1H Board= AKA, "High Resolution Embedded GUI Solution Kit for RZ/A1H" https://www.renesas.com/en-us/products/software-tools/boards-and-kits/renesas-demonstration-kits/ylcdrza1h.html

The "High Resolution Embedded GUI Solution Kit for RZ/A1H" is intended to showcase the graphics and image capture capabilities of the RZ/A1H as well as 3rd party middleware (non-OS and RTOS) using a 1280x800 LCD. However, the board can be used to run Linux as well.

USB-to-Serial Module

 * The board itself does not have a USB-to-Serial connection. Instead, you will have to use the PMOD connector that brings out SCIF3 and supply your own adapter.
 * The Digilent PmodUSBUART module seems to work pretty good because all you have to do is plug it in and you're all set. ( https://www.digikey.com/products/en?keywords=1286-1097-ND )

Install the RZ/A1 RSK BSP
$ git clone https://github.com/renesas-rz/rskrza1_bsp.git $ cd rskrza1_bsp
 * We will us the RSK BSP build environment even though we we will be using a YLCDRZA1H board. The reason is that the u-boot and Linux repositories on github also support YLCDRZA1H.
 * 1) Clone the BSP from github

Get Latest code from github
$ cd output/u-boot-2015.01 ; git checkout 2015.01-rskrza1 ; git pull ; cd ../.. $ cd output/linux-3.14 ; git checkout master ; git pull ; cd ../..
 * (which will include YLCDRZA1H updates)
 * Update the u-boot and kernel source inside the BSP by pulling updates from github
 * Start in the base of the BSP (where the build.sh file is, where you should have left off from the last step)

Install Segger Jlink Drivers for Linux

 * NOTE: This board has the JLINK HW already included on the board, so all you have to do is plug a USB cable into J17.
 * Install the "J-Link Software and Documentation Pack" from Segger's website
 * https://www.segger.com/downloads/jlink
 * Hint: You need to click the "Click for downloads" to actually find the download links.

Building

 * The tested build environment was Ubuntu. If using another distribution, some changes might be needed (but I'm not sure what exactly).
 * Lines that start with the symbol '$' are to be copy/pasted into the Linux PC terminal (without the $)
 * Lines that start wit the symbol '=>' are u-boot commands
 * Lines that start wit the symbol '#' are just comments

Build the File System
$ ./build.sh buidlroot $ ./build.sh buidlroot menuconfig
 * We do this first because we need Buildroot to download the toolchain that we will use to build u-boot and the kernel.
 * NOTE that I suggest the 'minimum' file system option when prompted becase it makes the build much quicker.
 * NOTE that because the Stream it uses a different serial port (SCIF3) as the RSK board(SCIF2), we will have to modify the Buildroot config from it's default RSK board value.
 * Now go back and switch the serial console (BR2_TARGET_GENERIC_GETTY_PORT from /dev/ttySC2 to /dev/ttySC3
 * System configuration -> Run a getty (login prompt) after boot -> (ttySC2) TTY port -> Change "ttySC2" to ttySC3"
 * Now use ESC to back out of the menu and save the new config.

$ ./build.sh buidlroot $ ./build.sh axfs
 * Run Buildroot again (will be quick this time)
 * Also build the AXFS XIP file image

Build u-boot
$ ./build.sh u-boot ylcdrza1h_defconfig $ ./build.sh u-boot

Build the Kernel and Device Tree
more coming soon...
