IMX6SX YOCTO

[2548903578]

Hi!

 I encountered a problem about imx6sx. I want yocto to generate uboot files about emmc. According to echo "UBOOT_CONFIG = \" emmc \"" >> conf / local.conf and MACHINE=<machine name> bitbake -c deploy u-boot-imx these two commands are still The uboot file of emmc cannot be generated. I did not find the corresponding .conf file for imx6sx under the directory imx-yocto-bsp/sources/meta-imx/meta-bsp/conf/machine. I just want to ask what should I do to generate the corresponding uboot image file of emmc.

Hi,

1. Use L5.4.24_2.1.0 ,  we didn't release document of L5.4.3_2.0.0.

2. Use standalone to compile u-boot and linux kernel.

In i.MX_Linux_User's_Guide.pdf,  see 4.5.11 How to build U-Boot and Kernel in standalone environment, please!

---Download u-boot source code

---Download linux-imx source code

---export toolchain through Yocto.

---install toolchain

....

3. compile u-boot

# make clean

# make mx6sxsabresd_emmc_defconfig

# make

It is easy to control some code or configurations for you in standalone operations.

Hope the information is helpful to you.

Have a nice day!

B.R,
