Rockchip官方純linux,kernel4.4.0

比現在firefly的kernel 3.10.0還新很多
而且firefly算是android轉過來的linux

高手可以研究看看嗎??

來分享給大家

这个好。。。。收下。。

不知与firefly RK3288板子兼容性可好？有人吃螃蟹吗~

按照說明把u-boot , kernel 都編譯出來了

可是
emmc boot
sd boot
通通失敗 , 都無法讓firefly 進入u-boot
不理解阿??? 高手在哪

Booting from emmc
Writing to the board with USB
For USB to work you must get your board into ROM boot mode, either by erasing
your MMC or holding the recovery button when you boot the board.

rk3288(upgrade_tool)
To create a suitable image and write it to the board:
tools/mkimage -n rk3288 -T rksd -d spl/u-boot-spl-dtb.bin u-boot-dtb.bin(normal)
tools/mkimage -n rk3288 -T rksd -d spl/u-boot-spl-nodtb.bin u-boot-dtb.bin(firefly)
sudo upgrade_tool db  ../rkbin/rk32/rk3288_boot.bin
sudo upgrade_tool wl 64 u-boot-dtb.bin ------------fail
sudo upgrade_tool wl 256 u-boot.img ---------------fail
sudo upgrade_tool rd

Booting from sdcard
Flash uboot
To write an image that boots from an SD card (assumed to be /dev/sdb)
(u-boot-spl-nodtb.bin for firefly)

tools/mkimage -n rk3288 -T rksd -d spl/u-boot-spl-dtb.bin out&&
sudo dd if=out of=/dev/sdb seek=64&&sudo dd if=u-boot-dtb.img of=/dev/sdb seek=256
Format sdcard
Enter into the uboot and issue the following command:
(otg should be connected, maskrom should be pressed)

gpt write mmc 0 $partitions
ums 0 mmc 0

这流程和现在的 firefly 硬体对得上吗?:o

发现在linux擦不了flash,用windows下的androidtool先擦后在操作都可以烧进了。但启动不起来。提示：

还在摸索中。。。。

我是sd boot

卡在讀不到zImage , 可是我真的有放到裡面

原来在虚拟机下面操作总是不行，现找了个硬盘装单系统ubuntu操作后。TF卡启动正常了。还差rootfs.

你真的可以讀到zImage耶

虛擬機器不行是什麼意思 , 我真的是虛擬機器

可是我zImage真的有放到 /dev/sdb6

你的步驟是什麼
可不可以說一下

之前是在win10下跑的虚拟机32位ubuntu，发现在uboot下用otg挂TF卡到ubuntu，怎样都挂不了。/dev下没有相关设备。在非虚拟机下没这问题 。    另外你要看看zImage是放在TF卡第一分区，具体是不是sdb6要看清楚了。昨天折腾了一下rootfs，但内核挂载不上。但uboot下用指令可以挂载。也能正常读到里面文件。。
