Compilation error while rebuild kernel

[MKana.1]

Hi hope you're well. 

I got stuck on part 6.Compile kernel source code->Compile and install on the current source code directory->make ARCH=arm uImage vmlinux dtbs LOADADDR=0xC2000040 giving an error as below. Thanks in advance!

Hi @MKana.1​ 

Did you made change in kernel source before to compile ?

Did you properly apply patches ?

1- No I didn't change anything even I didn't use git part if there is change that I might not know. Even it doesnt change if I use git.

2- I think I do everything as written. I know I did something wrong because it's tested and validated.

So you say the problem can be caused by unproper patch apply or changing kernel source codes. Could it be caused because of compiler or virtualbox or something else?

Hi @MKana.1​ which document are you following?

[MKana.1]

Sorry for late response. I'm following STM32MP1 Developer Package of Development zone. Link: https://wiki.st.com/stm32mpu/wiki/STM32MP1_Developer_Package

Hi @MKana.1​ ,

as @Community member​ already told you, just after you uncompressed the tarball you have to apply the patches included in the tarball.

Read carefully the file README.HOW_TO.txt

I don't know why ST is releasing sources in a so fragmented way instead of pre-applying the patches in the kernel.

Distinti Saluti / Best Regards

del this parameter and comment function 123: dwc2_hsotg_core_disconnect(hsotg);

all build and work :)

Hi @MKana.1​ ,

This build issue occurs if you're compiling the kernel with CONFIG_DWC2_HOST.

Normally, if you apply OpenSTLinux fragments (also available here: https://github.com/STMicroelectronics/meta-st-stm32mp/tree/thud/recipes-kernel/linux/linux-stm32mp/4.19) in addition to multi_v7_defconfig, kernel should be compiled with CONFIG_USB_DWC2_DUAL_ROLE and you shouldn't have build issue.

Anyway, a patch has been released on github to fix this build issue with drivers/usb/dwc2/drd.c : https://github.com/STMicroelectronics/linux/commit/2065bb653d0dfdcc7c5200512f00128685c9a0ca

Hi ,

thanks for the response. But even after applying everything on the latest tarball I am running into this error. 5.10.16 - Kernel Version

Trying to figure out for few days now. Any inputs will be appreciated.
