Behavior

USB drive appearing instead of CIRCUITPY drive.

Description

Hello, could someone help me understand why after installing the latest CircuitPython to my SAM E54 Xplained Pro, the "CIRCUITPY" drive does not appear but "USB Drive" appears instead?

When trying to open the "USB Drive", a notification appears: "Please insert a disk into USB Drive (D:)."

I'm using the latest bootloader version (3.15).

storage.erase_filesystem() did not solve the issue.

Additional information

No response

Here are some things to check:

See https://forums.adafruit.com/viewtopic.php?p=838854#p838854, and the whole thread. A user had trouble, and it turned out some board jumpers were set wrong.
(If I remember right:) A user had trouble with a newer SAMD21 Xplained board. It turns out Microchip changed the flash chip on the board during the chip shortage without much if any notification. Perhaps they did something similar on this board. Currently the board build is only expecting an N25Q256A chip. What do the flash chip markings say?
May be related to #6470.

Hi, the flash chip markings are: 26F064B

Please post a picture of the chip. It'll likely have a manufacturer's logo too.

chip Here is a picture of the chip.

Thanks! That looks like a MicroChip flash chip instead of micron as the board def says. Want to make a PR adding "SST26VF064B" to the list here: https://github.com/adafruit/circuitpython/blob/main/ports/atmel-samd/boards/same54_xplained/mpconfigboard.mk#L10 ? That's the full name of the MicroChip flash (nvm.toml define here.)

Thank you! I've tweaked it so it'll hopefully build.
