Hello sir,
Thank you for response.
Actually, I want to integrate Quectel EC200S-CN LTE modem with pine64 board. For LTE integration, we need to modify option.c ,qcserial.c, usb_wwan.c, and usb-wwan.h. Additionally we need to enable some of the features through menuconfig command.
As per our understanding, we need to first download kernel source in any of linux host system. After that do required change in above given file and perform procedures:
1). make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
2). make -j$(nproc) ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage modules
3). make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- INSTALL_MOD_PATH=output modules_install
After that we need to copy generated files in bootable SD card. But, now we don't know where we can find kernel source and performing all above steps true are true?. If above steps true then which file need to copy in SD card and which location.
Can you guide me for this or share any reference link?
All your suggestion are valuable for us.
