B9L lk2nd 2nd-stage build (RAM test only — never flash without a separate GO)

  • Base: lk2nd 23.1 e9c8b217 (same tree as lk2nd-build/src, cloned to ~/aurora-lkbuild/b9l-src; the original tree is untouched).
  • Patch: lk2nd-23.1-aurora-b9l.patch (msm8916 QUP4 SPI clock + iomap, gpio_config_blsp_spi, clock_config_blsp_spi clamped to 16 MHz, module lk2nd/aurora (st7735s.c), project hook AURORA_SPI_PANEL=1).
  • Command (in b9l-src): make -j4 TOOLCHAIN_PREFIX=arm-none-eabi- LK2ND_DTBS="msm8916-512mb-mtp.dtb" AURORA_SPI_PANEL=1 lk2nd-msm8916 (differences from the B9L-0 23.1 image: no LK2ND_FORCE_FASTBOOT, + AURORA_SPI_PANEL).
  • Toolchain arm-none-eabi-gcc 14.2.1 20241119. Output lk2nd-b9l-st7735s.img sha256 775986e2d562ff92840de1783d60899d23babb70fb6566a285600e99a4361499 (299024 B).
  • Splash variant (2026-10-03): + AURORA_SPLASH=1 → frame = b9/b9l/splash/swag.png (128x128, alpha 255 everywhere) converted by splash/mk-splash.py to RGB565 LE (aurora_splash.h, blob sha256 87955300). Patch: lk2nd-23.1-aurora-b9l-splash.patch. Output lk2nd-b9l-swag.img sha256 e6849a2b. Panel init code identical to 775986e2 (geo variant).
