10 months ago hi, It gave a compilation error as below, I think it's a kernel incompatibility.
~/soft_uart $ make
make -C /usr/src/linux-headers-6.1.21-v8+ M=/home/v2x/soft_uart modules
make[1]: Entering directory '/usr/src/linux-headers-6.1.21-v8+'

Looking at other issues, it seems that the kernel version is 4.x. Should I lower my kernel version?
Please fix the error,,
