iMXRT1024 - Seperate Debug Console and shell

GUnderdown — Wed, 15 Nov 2023 19:20:27 GMT

I would like to have the debug console put on USART1, and a true shell put on USART6. This way we can have debug messages printed over a clean port, and then have customers interact with the shell as a backup to setting information over the network/usb.

However, whenever I go to initialize the shell, the code asserts during

shell_status_t SHELL_Init(shell_handle_t shellHandle, serial_handle_t serialHandle, char *prompt)`

Specifically, it asserts after

status = SerialManager_OpenReadHandle(shellContextHandle->serialHandle, shellContextHandle->serialReadHandle); assert(kStatus_SerialManager_Success == status);

status here is "kStatus_SerialManager_Busy"

I have tried this with both non-blocking transfers as well as blocking transfers.

Here is my side of the init code

s_shellHandle = &s_shellHandleBuffer[0]; char * stringthingy = new char[16]; // should be enough for "shell@12345 #\0" // this is what will be printed before // the prompt // like user@computer $ or user@computer# // we will make it shell@serialNum # sprintf(stringthingy, "shell@%05u #", (unsigned int)GlobalHardware->GetHWInfo().hardwareSerialNum); SHELL_Init(s_shellHandle, g_serialHandle, stringthingy); // never gets beyone here SHELL_RegisterCommand(s_shellHandle, SHELL_COMMAND(viewEthernet)); SHELL_RegisterCommand(s_shellHandle, SHELL_COMMAND(viewSoftware)); SHELL_RegisterCommand(s_shellHandle, SHELL_COMMAND(viewHardware)); SHELL_RegisterCommand(s_shellHandle, SHELL_COMMAND(setHardware)); SHELL_RegisterCommand(s_shellHandle, SHELL_COMMAND(setEthernet)); //SHELL_Task(s_shellHandle); }

Here is the defines I pass in (as previously stated, have also tried with DEBUG_CONSOLE_TRANSFER_NON_BLOCKING)

Hi @GUnderdown ,

I have tried with the similar code on my board, but it works well.

I tested it based on the Shell demo with RT1024EVK, and debug console on semihost. Have you tried with the same ?

Have a great day,
Kan

I guess my biggest question is how do I tell the shell to print to USART6 instead of usart1?

@Kan_Li

How would I set it up to select the USART that the shell prints on? I want to have the shell on USART6, not semihost or USART1 (which is the default)
