tar -xvf Module.symvers-5.15.10-tinycore.gz

it reports the following err:
tar: invalid tar magic

Hi lovelypp
It's not a  tar  file. Try:

Code: [Select]

gunzip Module.symvers-5.15.10-tinycore.gz

[lovelypp]

thank you
I unzip it successfully and put it to the Kernal source dir.
but when compile my driver, it reports:
ERROR: modpost: "phys_base" [/mnt/sda3/mydrv/anet/anet.ko] undefined!
make[2]: *** [scripts/Makefile.modpost:134: /mnt/sda3/mydrv/anet/Module.symvers] Error 1

How did you prepare the kernel source?

[lovelypp]

tar -xf linux-5.15.10-patched.txz
$ cd linux-5.15.10
$ make mrproper
$ cp ../config-5.15.10-tinycore64 .config
$ make menuconfig
$ make prepare
$ make modules_prepare
$ make modules
$ make modules_install

Copy the module.symvers file to the kernel source directory, after you have ran the prepares, just before you run make modules.
