T1Sim badge v01

T1Sim badge v01

Initial downloadable stock firmware package for the T1Sim badge.
Built from firmware main revision 0aa12fb1121f8108f21f9e6d870607f3055385e2 using Pico SDK 2.3.0 and
Arm GNU 14.2.Rel1, Release configuration.

Validated: firmware build, complete RP2350 UF2 structure, board identity,
version, flash address bounds, manifest size, and SHA-256 checksums.
These checks do not establish hardware operation. This publication has not
been flash-tested on a physical T1Sim badge, or through the GUI on macOS/Linux.

Use Tools > Firmware Update > T1Sim badge in a GUI build containing the
new updater, or copy the standalone UF2 to this board's RP2350 BOOTSEL drive.
Keep USB power connected. Internal data and microSD contents are preserved.

The RP2350-E10 workaround uses 0x107fff00 in the final sector of the lower
8 MiB firmware area. The default 0x10ffff00 would touch the internal data
area and is rejected by the packaging tools and GUI. The initial download
was withdrawn before this corrected package was published.
