v1.2.15 — Fix native haptics + speaker audio regression (closes #11)

on GitHub

What's fixed

Native haptics and controller speaker audio now work reliably at 150 MHz alongside the auto-haptics feature.

Root cause (issue #11)

PICO_FLASH_ASSUME_CORE1_SAFE=1 was an unsafe shortcut: it told the SDK that core1 never touches flash, but TinyUSB, btstack and cyw43 still had code in flash. When core0 called config_save() (flash erase/program), core1 was mid-flight in flash — causing XIP cache corruption, audio dropout, and native haptic regression.

Fix

• PICO_FLASH_ASSUME_CORE1_SAFE=0 — SDK now properly parks core1 before any flash operation
• flash_safe_execute_core_init() in core1_entry() — registers core1 as a flash-safe victim
• PICO_EMBED_XIP_SETUP=1 — reinitialises XIP cache after each config_save()
• src/ram_mem.c — RAM-resident memcpy/memset/memmove (RP2350 bootrom no longer exports these)
• WDL_Resampler, libopus (celt/silk), pico_util queue relocated to SRAM via cmake/relocate_to_ram.cmake

How to update

Flash the .uf2 file: hold the BOOTSEL button on the Pico 2W while plugging it in, then drag-and-drop the file onto the drive that appears.
