Boot from eimnor in sabreauto

nishad_kamdar — Mon, 14 Dec 2015 10:31:25 GMT

Hello,

I have a custom imx6q board which is based on the 'sabreauto' reference board.

I have a spansion CFI NOR flash on board for booting.

How do i generate the uboot with eimnor config?

I am using Yocto and fsl-community-bsp with 3.10.17 kernel

I tried changing the

UBOOT_CONFIG ??= sd"

UBOOT_CONFIG[sd] = "mx6qsabreauto_config,sdcard"

UBOOT_CONFIG[eimnor] = "mx6qsabreauto_eimnor_config"

UBOOT_CONFIG[nand] = "mx6qsabreauto_nand_config,ubifs"

UBOOT_CONFIG[spinor] = "mx6qsabreauto_spinor_config"

UBOOT_CONFIG[sata] = "mx6qsabreauto_sata_config"

UBOOT_CONFIG[mfgtool] = "mx6qsabreauto_config"

in imx6qsabreauto.conf

UBOOT_CONFIG ??= eimnor"

UBOOT_CONFIG[sd] = "mx6qsabreauto_config,sdcard"

UBOOT_CONFIG[eimnor] = "mx6qsabreauto_eimnor_config"

UBOOT_CONFIG[nand] = "mx6qsabreauto_nand_config,ubifs"

UBOOT_CONFIG[spinor] = "mx6qsabreauto_spinor_config"

UBOOT_CONFIG[sata] = "mx6qsabreauto_sata_config"

UBOOT_CONFIG[mfgtool] = "mx6qsabreauto_config"

but i get the following error

make: *** No rule to make target `mx6qsabreauto_sata_config'. Stop.
| make: *** [mx6qsabreauto_sata_config] Error 1
| ERROR: oe_runmake failed
| WARNING: exit code 1 from a shell command.

What should i do to boot from eimnor?

Thank your for your time,

Have you tried to compile it not using bitbake?

export ARCH=arm

export CROSS_COMPILE=/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-

make distclean;

make mx6qsabreauto_eimnor_config

make

I tried it using BSP 3.14.28 and compiled with not issues.

Best Regards,

Alejandro

Hi,

Thanks for the reply.

I tried using 1.6.2 toolchain to compile the u-boot-fslc.

I still get the same error.

My BSP is 3.10.17.

How do i switch to the new BSP?

I manually downloaded the u-boot from 3.14.28,

from the following link:

Freescale/u-boot-fslc at v2014.04 · GitHub

and tried compiling it

It gave the error

nishad@nishad-VPCEB34EN:~/fsl-community-bsp/u-boot-fslc$ make mx6qsabreauto_eimnor_config

***

*** Can't find default configuration "arch/../configs/mx6qsabreauto_eimnor_defconfig"!

***

make[1]: *** [mx6qsabreauto_eimnor_defconfig] Error 1

make: *** [mx6qsabreauto_eimnor_config] Error 2

Nishad

Hi,

I was able to solve the issue. I am able to build the eimnor u-boot using bitbake now.

The fsl-default-providers.inc file had the following contents:

# Freescale BSP default providers

PREFERRED_PROVIDER_virtual/xserver = "xserver-xorg"

PREFERRED_PROVIDER_virtual/kernel ??= "linux-imx"

PREFERRED_PROVIDER_u-boot ??= "u-boot-fslc"

PREFERRED_PROVIDER_virtual/bootloader ??= "u-boot-fslc"

So my BSP was by default using u-bot-fslc image which does not support "mx6qsabreauto_eimnor_config."

After reading the "Freescale_Yocto_Project_User's_Guide" i found out that it uses u-boot-imx as the default bootloader.

So i modified the fsl-default-providers.inc file to:

# Freescale BSP default providers

PREFERRED_PROVIDER_virtual/xserver = "xserver-xorg"

PREFERRED_PROVIDER_virtual/kernel ??= "linux-imx"

#PREFERRED_PROVIDER_u-boot ??= "u-boot-fslc"

#PREFERRED_PROVIDER_virtual/bootloader ??= "u-boot-fslc"

PREFERRED_PROVIDER_u-boot ??= "u-boot-imx"

PREFERRED_PROVIDER_virtual/bootloader ??= "u-boot-imx"

and changed the imx6qsabreauto.conf to

UBOOT_CONFIG ??= "eimnor"

UBOOT_CONFIG[sd] = "mx6qsabreauto_config,sdcard"

UBOOT_CONFIG[eimnor] = "mx6qsabreauto_eimnor_config"

UBOOT_CONFIG[nand] = "mx6qsabreauto_nand_config,ubifs"

UBOOT_CONFIG[spinor] = "mx6qsabreauto_spinor_config"

UBOOT_CONFIG[sata] = "mx6qsabreauto_sata_config"

UBOOT_CONFIG[mfgtool] = "mx6qsabreauto_config"

Now the bitbake does not yield any error as it did before.

Still need to test the u-boot on hardware though.

Thanks for your time,

Best regards,

Nishad
