I will receive my samd21 xplained pro soon and wanted to ask if someone could help me. I'm looking for a hint/example for using the internal or external serial flash as a MSC block storage.
I found an example for an SD card but I'm really new to the samd21 as well as to MSC.
Any help is highly appreciated.
UPDATE: I just found this example: http://asf.atmel.com/docs/3.40.0/common.services.usb.class.msc.device.example.samd21_xplained_pro/html/index.html
It can mount any of the available memories as MSC. Exactly what I wanted. Now I do have another question. If I place a .txt file on the internal or external flash. How can I read this file from the SAMD21 side? Does it have to be fatfs formatted?
