| + | If you have a USB-UART console, you can easily check the u-boot version using 'ver' on u-boot stage. \\ | ||
| <code> | <code> | ||
| - | $ tar zxvf c2_bootloader.tar.gz | + | Hit [Enter] key twice quickly during u-boot loading and enter 'ver' or 'version'. |
| - | $ cd c2_bootloader | + | |
| - | $ ./sd_fusing.sh <device/path/of/your/card> | + | odroidc2# version |
| + | U-Boot 2015.01-00089-gdfb8216 (Apr 09 2016 - 06:20:43) | ||

| + | |||
| + | Or you can check it after kernel booting on userspace using a simple shell script. | ||
| + | <file sh getUbootVer.sh> | ||
| + | #!/bin/sh | ||
| + | dd if=/dev/mmcblk0 of=/tmp/temp.bin bs=512 skip=97 count=1334 status=none | ||

| + | rm /tmp/temp.bin | ||
| + | </file> | ||
| + | |||
| + | <code> | ||
| + | root@odroid64:~# vi getUbootVer.sh | ||
| + | root@odroid64:~# sudo chmod a+x getUbootVer.sh | ||
