Menuconfig or how to configure kernel make ARCH=arm uImage LOADADDR=<loadaddr of kernel>

[kagan_senkeser]

Hello,

I'm ustin stm32MP135F-DK and try to modify device tree 
Menuconfig or how to configure kernel - stm32mpu
in this link I came to 

make ARCH=arm uImage LOADADDR=<loadaddr of kernel>

And ı getting this error how can ı solve it

Hi @kagan_senkeser ,

I suggest you to follow this page instead : https://wiki.st.com/stm32mpu/wiki/How_to_cross-compile_with_the_Developer_Package#STM32MP135F-DK_and_STM32MP157F-DK2_simple_example

or the README_HOW_TO you can find in the developer package

Hi @Gregory PLANCHON 

I'm already following this page but in part 3.2
But it sends me to Menuconfig or how to configure kernel - stm32mpu
also in menuconfig there is no size in megabytes I found device drivers -generic driver options but there is not

Navigate to "Device Drivers - Generic Driver Options"

• • select "Size in Megabytes"
  • modify its value to 256
  • exit and save the new configuration

• Check that the configuration file (.config) has been modified

grep -i CONFIG_CMA_SIZE_MBYTES .config
CONFIG_CMA_SIZE_MBYTES=256

• Cross-compile the Linux kernel: see Menuconfig or how to configure kernel

• Update the Linux kernel image on board: see Menuconfig or how to configure kernel

• Reboot the board: see Menuconfig or how to configure kernel

• Get the new value of the CMA size (256 Mbytes) through the analysis of the target boot log

Hi @kagan_senkeser ,

So if I understand correctly, your objective is to modify the value of CONFIG_CMA_SIZE_MBYTES?

I'd like to ask you a few questions to help you solve your problem:
Are you sure you've sourced your SDK correctly?
Have you tried searching for CMA_SIZE_MBYTES in menuconfig with the search option?
Can you tell me what kernel version you're running?

Regards,

Grégory

Hello,

Have you tried searching for CMA_SIZE_MBYTES in menuconfig with the search option?
this worked thank you.
