Now we have this Pico application below based on tinyUSB to program Eve connected Flash(e-flash): https://github.com/BRTSG-FOSS/pico-brteve/tree/develop/tools/uf2

We want to add the support:

[x] Detect the SD card and read SD card to program the flash image to e-flash if there is the pre-defined file "e-flash.bin" or "e-flash-v.bin" at the root directory.
[x] Read the eve-connected flash and write the data into SD card with the name e-flash-readback.bin if the pre-defined file "e-flash-v.bin" at the root directory.
[x] the pin assignment of Eve SPI interface by users (optional)

If e-flash.bin is detected and flashed, the INFO_UF2.TXT will have this line:

X-Eve-Flash-image: /e-flash.bin

Otherwise it has this line:

X-Eve-Flash-image: NONE

Example:

Added EFLASH.BIN entry so user can read the whole EVE's connected flash just by copying it on Window Explorer:

The pin assignment of Eve SPI interface by users is supported.

Usage: Edit file SPI_PIN.CNF directly by notepad and just save it to reflect the change.
