FTDI Driver in Kernel

laplace12 — Fri, 24 Jun 2022 21:10:32 GMT

I am running lsdk 1906 and ran the command "flex-builder -c linux:custom -a arm64" to pull up the GUI so i can select the ftdi driver. Running "flex-builder -c linux -a arm64" and then "flex-builder -i mkbootpartition -a arm64" to create kernel tarball im build/image. I also went inside build/image/linux_xx folder to check if the ftdi_sio.ko is in there but could not find anything relate to that. How do i know if the kernel tarball has the ftdi_sio driver in it when i don't see it in the linux folder.

Please find folder build/linux/linux/arm64/LS/lib whether ftdi_sio.ko exists, if yes, it will be integrated in modules folder in bootpartition tar ball.

i don't see the ftdi driver in the lib/modules/4.19.46/kernel/driver/usb. When i create the boot tarball and create the linux_4.19)LS_arm64_<timestamp>.tgz, and put that on the sd card, i see that ftdi driver exist but could not find it in the lib folder.
