Just got a ‘BananaPro<\/strong>‘ ARMv7 board, and updated it to Kernel 4.4-rc4 (from kernel.org<\/strong><\/span>) and Fedora 23.<\/p>\n

\"bananapro\"<\/a>More details are here:\u00a0 http:\/\/linux-sunxi.org\/LeMaker_Banana_Pro<\/a><\/p>\n

I compiled U-Boot from the latest (2015.10) released version, from ftp.denx.de\/pub\/u-boot\/<\/span><\/strong> :<\/p>\n

# cd u-boot<\/strong><\/span>\r\n# make Bananapro_defconfig<\/strong><\/span>\r\n# make ARCH=arm CROSS_COMPILE=arm-linux-gnu-  <\/strong>(or whatever cross-compiler you are using)<\/span><\/span><\/pre>\n
Then as root, copy to the SDCard (mounted via USB..)<\/p>\n
# dd if=u-boot-sunxi-with-spl.bin of=\/dev\/sde bs=1024 seek=8<\/span><\/strong><\/pre>\n
I used one of the standard Fedora 23 images (Workstation), from https:\/\/arm.fedoraproject.org\/<\/a><\/p>\n
The initial kernel (cross-)compile was done on an x86_64 system, and copied to the F23 SDCard.\u00a0\u00a0 Further compiles will be done on the BananaPro itself, as follows:<\/p>\n
make sunxi_defconfig<\/span><\/strong>\r\nmake xconfig (select Allwinner A20 - sunx7i)<\/span><\/strong>\r\nmake -j3 zImage<\/span><\/strong>\r\nmake dtbs<\/span><\/strong>\r\nmake -j3 modules<\/span><\/strong>\r\nmake modules_install<\/span><\/strong>\r\nmake firmware_install<\/span><\/strong>\r\ncp arch\/arm\/boot\/zImage \/boot\/uboot<\/span><\/strong>\r\ncp arch\/arm\/boot\/dts\/sun7i-a20-bananapro.dtb \/boot\/uboot<\/span><\/strong><\/pre>\n
Note that many BananaPro examples show uImage, but zImage works fine….\u00a0 To avoid anything being overwritten by Fedora updates, I created a \/boot\/uboot directory for the compiled kernel image and dtb..\u00a0\u00a0\u00a0 I modified the kernel config selections as necessary for Fedora (EXT4 POSIX, etc., and devtmpfs, and Tmpfs POSIX, etc..)<\/p>\n
I modified the U-Boot parameters as follows:<\/p>\n
setenv bootdelay 10<\/strong><\/span>\r\nsetenv bootargs \"console=ttyS0,115200 console=tty0 console=tty1 root=\/dev\/mmcblk0p3 rootfstype=ext4 elevator=deadline rootwait\"<\/strong><\/span>\r\nsetenv bootcmd \"ext4load mmc 0:1 0x46000000 uboot\/zImage; ext4load mmc 0:1 0x49000000 uboot\/sun7i-a20-bananapro.dtb; bootz 0x46000000 - 0x49000000\"<\/strong><\/span>\r\n< then saveenv<\/strong><\/span> to save to mmc ><\/span><\/pre>\n
Then the system booted OK:<\/p>\n
