Hi @Alan & @Frank sir, I was also thinking the same, first check for the drivers I need and then copy it and the change as per my needs. Then change Makefiles, Make.defs, and Kconfigs files to make the driver include. Then make them an app to run on picocom.
Will try to change driver as per need and try to make driver into app to get it run on picocom. Thanks for the information.
