Hello Everyone,

Trying to build OpenWrt for FRDM-LS1012A-PA, but the boot loader selection is missing the menuconfig of Openwrt.

I followed below steps in Ubuntu 17.10 host,working with commit id 0f1a1489a6c584d7de6680a65b457acf328818bd 

#  git clone https://github.com/lede-project/source.git

# ./scripts/feeds update -a

# ./scripts/feeds install -a

# make menuconfig

Target System (NXP Layerscape)

Subtarget (ARMv8 64-bit based boards)  --->

Target Profile (ls1012afrdm-armv8_64b)  --->

Now when I check the "Boot loader option section"   No boot loader selection listed, Attaching the screen shot also for reference.

Could you please help me to resolve this?, How can I build Openwrt for ls1012afrdm

Thanks

Hi abhilash,

I had the same concern when I started working with this board in OpenWRT, but all is ok. The u-boot configs are automatically created when you chose the FRDM-LS1012A platform. You could see them in the .config file in /home/administrador/lede/source/ directory.

If you compile it, in directory:

/home/administrador/lede/source/build_dir/target-aarch64_generic_musl/uboot-layerscape-ls1012afrdm/uboot-layerscape-2017.09

you could see the u-boot binary.

I've write a small guide for anyone that want to try this interesting board with openWRT.

In directory:

/home/administrador/lede/source/bin/targets/layerscape

you could see the whole binary image:

openwrt-layerscape-armv8_64b-ls1012afrdm-squashfs-firmware.bin

that includes the following map of binary code:

spi Lede 17.01 file system map:

000 0000 – 00F FFFF  RCW                1MB

010 0000 – 03F FFFF  uboot                3MB

040 0000 – 09F FFFF  ppa                   6MB

0A0 0000 – 0EF FFFF  ppfe                  5MB

0F0 0000 – 0FF FFFF  dtb                    1MB

100 0000 – 0FF FFFF  kernel               16MB

200 0000 – 3FF FFFF  rootfs                30MB

You could see how is created in:

/home/administrador/lede/source/target/linux/layerscape/image/Makefile

In directory:

/home/administrador/lede/source/build_dir/target-aarch64_generic_musl/linux-layerscape_armv8_64b

you could find the following files:

image-fsl-ls1012a-frdm.dtb   Device tree binary file. Created from dts

ls1012afrdm-30M.root.ext4   Root file system, in ext4 format

ls1012afrdm-kernel.bin         Linux kernel, in uImage format

Be careful when writing spi flash, because if you write a wrong RCW binary the only way to recover the board is Codewarrior TAP, an expensive tool ($500) that NXP forces us to buy, because the Layerscape processors has no usb boot code, and the only way to boot is spi rcw. USB CMSIS can't write RCW (why?). For new boards you should buy it, or include a mechanism to write spi flash externally.

I use to write only the rootfs or kernel directly.

u-boot ethernet driver in openwrt give errors in my board (in linux ethernet works very well). That's why I use usb pendrive to load the files.

The USB has to be powered with an external 5V power supply to work. I use a micro-usb to usb-a female adapter to connect the pendrive.

The pendrive has to be formated as fat.

Then, the commands to load a new kernel are:

usb start
fatload usb 0:1 96000000 ls1012afrdm-kernel.bin
sf probe 0:0
sf erase 1000000 +$filesize
sf write 96000000 1000000 $filesize

The commands to load a new root file system are:

usb start
fatload usb 0:1 96000000 ls1012afrdm-30M.root.ext4
sf probe 0:0
sf erase 2000000 +$filesize
sf write 96000000 2000000 $filesize

RCW file is in directory:

/home/administrador/lede/source/build_dir/target-aarch64_generic_musl/ls-rcw-2017.09-ls1012afrdm/ls-rcw-2017.09/ls1012afrdm/N_SSNP_3305/PBL_0x33_0x05_800_250_1000_default.bin

To change it for a new board, you should use Codewarrior Development Studio for Networked applications.

This tool is not free, like in almost all manufacturers nowadays (for example Texas Instruments CCS), It is not even cheap: it cost $3000. But you could use the evaluation version to change RCW.

But you should have in mind that if you want to make your own board and you want to use the ddr validation tool to

calibrate ram, you should buy the Specialist version of Codewarrior that cost $5000.

I think that semiconductor manufacturers has to get money from silicon chips, not from developer tools. Developer tools has to be free to atract developers to their platforms. And that is specially clear here, because under Codewarrior there is an open source tool: Eclipse, that NXP is using at no charge.

If you make your own board, you could need to change dts to reflect changes from FRDM-LS1012A board.

There is two kind of dts files: the u-boot dts files, and the kernel dts files.

The u-boot dts files get integrated in u-boot binarty and you could find them in:

/home/administrador/lede/source/build_dir/target-aarch64_generic_musl/uboot-layerscape-ls1012afrdm/uboot-layerscape-2017.09/arch/arm/dts/fsl-ls1012a-frdm.dts

/home/administrador/lede/source/build_dir/target-aarch64_generic_musl/uboot-layerscape-ls1012afrdm/uboot-layerscape-2017.09/arch/arm/dts/fsl-ls1012a-frdm.dtsi

The kernel dts files should be written in spi, and you could find them in:

/home/administrador/lede/source/build_dir/target-aarch64_generic_musl/linux-layerscape_armv8_64b/linux-4.9.67/arch/arm64/boot/dts/freescale/fsl-ls1012a.dtsi

/home/administrador/lede/source/build_dir/target-aarch64_generic_musl/linux-layerscape_armv8_64b/linux-4.9.67/arch/arm64/boot/dts/freescale/fsl-ls1012a-frdm.dts

The commands to load a new dtb are:

usb start
fatload usb 0:1 96000000 fsl-ls1012a-frdm.dtb
sf probe 0:0
sf erase F00000 +$filesize
sf write 96000000 F00000 $filesize

@Miguel: I tried your described flashing procedure with my recently shiped FRDM board. However the kernel isn't executed due to a decompression error:

I built the openwrt firmware on my local desktop using subtarget "ARMv8 64-bit" and target profile "ls1012afrdm-armv8_64b". I used the kernel and userspace binaries that are created in the described folders to flash these two files ("ls1012afrdm-kernel.bin" and "root.ubifs") to the address 1000000 and 2000000.

Like this:

tftp 0x96000000 ls/ls1012afrdm-kernel.bin
sf probe 0:0
sf erase 1000000 +$filesize

sf write 96000000 1000000 $filesize

tftp 0x96000000 ls/root.ext4
sf probe 0:0
sf erase 2000000 +$filesize

sf write 96000000 2000000 $filesize

tftp 0x96000000 ls/image-fsl-ls1012a-frdm.dtb
sf probe 0:0
sf erase F00000 +$filesize
sf write 96000000 F00000 $filesize

reset

uBoot seems to recognize the kernel in some regard and tries to decompress it. But gzip fails with error -1.

The only difference I did was loading the image using the tftp command to load the image from my atftp server...

I also tried to boot an initramfs image. But this didn't work neither :-(...

Any ideas?

Hi,

What is your uboot init script?

Could you send a printenv result?
