This patch adds support for the AVNET RZBoard V2L. The board support creates a bootable sd card image. The board is shipped with a u-boot inside its eMMC. The board support uses this u-boot and does not build and deploy a u-boot onto the sd card. Instead the sd card only contains a uEnv.txt, a kernel image and the rootfs.

RZBoard V2L =========== https://www.avnet.com/wps/portal/us/products/avnet-boards/avnet-board-families/rzboard-v2l/ This board support creates a bootable sd card image for the AVNET RZBoard V2L. This board is shipped with a u-boot inside its eMMC. This board support uses that u-boot and only puts uEnv.txt, kernel image and rootfs onto the sd card. Build: ====== $ make rzboard_v2l_defconfig $ make Files created in output directory ================================= output/images . ├── Image ├── boot.vfat ├── rootfs.ext2 ├── rootfs.ext4 ├── rootfs.tar ├── rzboard.dtb ├── sdcard.img └── uEnv.txt Creating bootable SD card: ========================== Simply invoke (as root) sudo dd if=output/images/sdcard.img of=/dev/sdX && sync Where X is your SD card device. Booting: ======== Configure board for sd card boot: --------------------------------- Set the 'BOOT1' switch (next to the audio jack) to '1' (away from 'ON') in order to let the board boot kernel and rootfs from SD card. Serial console: --------------- The RZBoard V2L has a 4-pin header "J19" right next to the micro USB. Its layout can be seen in the Quick-Start Guide, or the Hardware User Guide, obtainable from: https://www.avnet.com/wps/portal/us/products/avnet-boards/avnet-board-families/rzboard-v2l/ The uart pins are as follows (from left to right - orientation according to the board's labeling): pin 1: n/a (most away from the board's corner) pin 2: tx pin 3: rx pin 4: gnd (nearest to the board's corner) Baudrate for this board is 115200. Power-Up: --------- Plug in a suitable USB-C power supply and press the button 'S1' (next to the USB-C port) for 2 seconds until the LED goes on. Login: ------ Enter 'root' as login user, and the prompt is ready.
