Hi Alison,
I created a busybox file system. So I have a folder on the host that contains: /bin /sbin /tmp /proc /usr /lib ...
Can you please explain how should I create a root file system with genext2fs (or with anotehr utility) ?
Thank you, Z.V ________________________________________ From: Alison Wang [alison.wang@nxp.com] Sent: Thursday, January 05, 2017 4:13 AM To: Vered Zvi; u-boot@lists.denx.de Subject: RE: [U-Boot] mkimage for ls1021a-twr.dtb
For dtb, you can use ls1021a-twr.dtb directly. No need to use mkimage.
To generate uImage, you can use mkimage for it.
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux Kernel" -d arch/arm/boot/zImage uImage.ls1021a

Hello,
I'm compiling vanilla 4.1.13 for ls1021a with gcc created with crosstool-ng Upon kernel build completion I got the file: ls1021a-twr.dtb
Then I ran: mkimage -A arm -O Linux -C none -T kernel -n 3.14.4 -d ls1021a-twr.dtb uImage.dtb
using tftp I downloaded: uImage -> 0x83000000 uRamdisk -> 0x88000000 uImage.dtb -> 0x8F000000 bootm 83000000 88000000 8F000000
Upon booting uImage.dtb I got: ERROR: uImage is not a fdt - must RESET the board to recover. Could not find a valid device tree
What am I doing wrong ?
I have a uImage.dtb taken from NXP's Yocto project. With this file I'm getting: ## Flattened Device Tree blob at 8f000000 Booting using the fdt blob at 0x8f000000 Loading Kernel Image ... OK Using Device Tree in place at 8f000000, end 8f008469
With my file I'm getting: ## Flattened Device Tree from Legacy Image at 8f000000 Image Name: Iamge Type: ARM Linux .. .... ERROR: uImage is not a fdt - must RESET the board to recover. Could not find a valid device tree
Thank you in advance, Z.V
