commit b42ec9a2c1858d95f570736d2ceefcf9df5a9594 Author: yukangzhi <[email protected]> AuthorDate: Wed Aug 26 14:21:15 2026 +0800 boards/esp32s3-devkit: disable C++ in usbmsc to avoid esptool align assert The esp32s3-devkit:usbmsc config uses CONFIG_ESPRESSIF_SIMPLE_BOOT, so the image is packaged with "esptool elf2image --ram-only-header". With esptool v5.2.0, that path asserts that each flash segment satisfies (f.tell() + 8 + BOOTLOADER_FLASH_OFFSET) % IROM_ALIGN == segment.addr % IROM_ALIGN When .flash.text lands right on a 64 KB (IROM_ALIGN) boundary the assertion cannot be satisfied and elf2image fails with AssertionError, even though NuttX itself links cleanly. usbmsc is a plain C test and does not need the C++ runtime. Disabling CONFIG_HAVE_CXX / CONFIG_HAVE_CXXINITIALIZE moves .flash.text off the IROM_ALIGN boundary so the SIMPLE_BOOT image can be generated, without changing the boot mode or the test's intent.
