USB HOST (PEN DRIVE)

[eliezer_fortron]

Hello, I have an IMXRT1050-EVKB kit.
I'm trying to create .txt file and write to a thumb drive, but all examples of the SDK teach only to communicate with terminal (Tera Term).
Has anyone ever written a txt file on the thumb drive? Can you help me?

Hi Eliezer,

You could take as reference/base the “host_msd_fatfs_bm” SDK example (from SDK v2.4.2 for IMXRT1050-EVKB board), that access to USB stick folders/files:

usb_examples->host_msd_fatfs_bm

Attached you can find the readme PDF file of such example.

CAUTION: This example erases all the content of the connected USB stick (performs a format).

Hope this will be useful for you.
Best regards!

Hello Carlos,
I imported the SDK sample and followed step by step into PDF but it did not work.
Is something missing to be done?

Hi Eliezer,

Please ensure that you are connecting the USB stick on micro USB connector U9, using a proper micro USB - USB Host adapter (that ties to GND the ID pin).

Hope this will be useful for you.
Best regards!

Hi Carlos, I've been able to find what I need.
Thanks for listening.

Ola Carlos, set the example right.
I am trying to create a .txt file to save in PEN DRIVE but there is a lot of stuff in that code, I'm pretty confused, I'm new to NPX.
I am using as base the FatFs - Generic FAT Filesystem Module.
I am not able to find the functions that tests if the pen drive is connected in order to generate my .txt file and when it is disconnected.
