Hello Edk2 team,
We are trying to change the UART Baud rate dynamically from UEFI shell using
"sermode" command in our ARM64 based platform.
I see the code flow of sermode call as below :
ShellCommandRunSerMode() -> SerialSetAttributes() ->
SerialPortSetAttributes()
SerialSetAttributes() <-
TerminalDriverBindingStart() ->
SerialSetAttributes() -> SerialPortSetAttributes()
TerminalDriverBindingStart() <-
SerialSetAttributes() <-
TerminalConInReset() ->
SerialReset () -> SerialPortInitialize()
TerminalConInReset() <-
SerialReset() <-
TerminalConInTimerHandler() ->
SerialSetAttributes() -> SerialPortSetAttributes()
TerminalConInTimerHandler() <-
SerialSetAttributes()
ShellCommandRunSerMode() <-
I am not able to understand why SerialSetAttributes and SerialReset are being
called, while the first call to SerialSetAttributes has not yet completed.
Is this code flow right ? am I missing something ?
Thanks & Regards,
Pankaj Bansal
