Are you running any PX4IO drivers or RC  input?

Subject: Serial console strange behaviour

Hi,

Custom board stm32f7, PX4 based project - moved from NuttX 8.2 to 10.0.0.
If serial dev console (CONFIG_USART6_SERIAL_CONSOLE=y) is used, it works:
prints all corresponding output on boot, but then

"nsh> " is shown only when I start typing in putty.
"ls" command shows only the first output line. Other lines are shown only
if I type at least one symbol.
I tried with and without CONFIG_USART6_RXDMA - same result.

USB CDC ACM console works OK.

Any thoughts on what can cause such behavior?

With best regards, Oleg
