Micro-python repl, mounting sd card through serialport

## What am I trying to do?

Trying to mount the sd card by sending python code through the serialport that is executed on my devices micro-python repl.

## What's my problem?

When I send information through the serialport the code is executed on the device's micro-python repl.
I am trying to execute the following code on my device's repl


Code: Select all

port.write("os.mount(machine.SDCard(),'/sd')\r\n")
However I am met with this error

Code: Select all

E (1066260) sdmmc_sd: sdmmc_init_sd_scr: send_scr (1) returned 0x109
I know that mounting the sd card from the repl is possible because I am able to mount the sd card when I execute that code without sending it through serialport(tera term). I am using serialport node js to write to the port.

Just confused as to why I am met with that error when I try to execute the code from the computer(serial) whereas otherwise no errors are met.
