Share files from MCU's LittleFS to a PC

[PaulNewf]

Has a "standard way" developed to share the files on an MCU's LittleFS with a PC (Through USB or UART)?

Wishful Application:

• MCU to have SpiFLASH with LittleFS.
• PC connects to MCU (USB CDC using D+/D- on a USBC connector).
• PC = Standard Windows Laptop, require no special software or driver installs by customer (i.e. MCU emulate a Thumbdrive)
• PC able to retrieve log files from LittleFS through MCU
• PC able to drop config files (and maybe firmware updates) to LittleFS that MCU will use after next reset.
• STM32L476 (single USBFS)

Just sharing my thoughts here (I'm facing same problem):

• You can use https://github.com/apache/mynewt-mcumgr to transfer files using fs download/upload commands over UART/BT.
• Implement USB MTP Class if you have USB support in your project.
