We have used L4T 32.4.3 BSP and customized it for our carrier board, I am facing some issue with Serial as It was working fine with earlier BSP (L4T 32.4.1) with same carrier board.
there are 4 tty nodes ttyTHS0,ttyTHS01,ttyTHS04,ttyTHS06.
If I transfer data as below, I am seeing these behaviors:
ttyTHS0 → ttyTH1 :no data
ttyTHS1 → ttyTH0 : echoed in 1
ttyTHS4 → ttyTH6 :echoed in 4
ttyTHS6 → ttyTH4 : echoed in 6
AGX Xavier to external node/ laptop via Tera term using serial to USB
tera term → ttyTHS0 : no data
ttyTHS0 → tera term :no data
tera term → ttyTHS1 : OK but sometime it is getting echoed
ttyTHS1 → tera term :OK
Can you please suggest on this?
