Startup crashes with PSRAM enabled on ESP32-WROVER-E-N8R8 (Cache disabled but cached memory region accessed)

Postby mrpace2 » Thu Apr 18, 2024 10:31 am

Enabling PSRAM (CONFIG_PSRAM=y) causes startup code to crash consistently. Board works fine without PSRAM enabled.

  • Hardware: custom board using ESP32-WROVER-E-N8R8
  • Toolchain: PlatformIO latest (platform=espressif32, framework=espidf), uses IDF 5.2.1
  • OS: Linux Mint

See https://github.com/platformio/platform- ... ssues/1360. Haven't tried myself, though.
