The original kernel version used was the kernel of Linux 3.2, which has soft serial port (SUART). However, as the version was too low to support many new libraries, we need to upgrade the kernel version to the new version (SDK is 4.14.79).We found in the upgrade of the new kernel source no Pru extension software serial port related driver source code and firmware, how to solve this problem?
