Failed to init external RAM: BLE configuration for DEVKIT v1
I was getting this error & a crash loop when trying to use the first BLE iBeacon example with a DEVKIT v1 board:
E (372) psram: PSRAM ID read error: 0xffffffff
E (376) cpu_start: Failed to init external RAM!
After some research and realizing it has no external RAM, the solution was to change this configuration:
Component config -> ESP32-specific -> Support for external, SPI-connected RAM -> DISABLE
Thought this might be a good thing to mention as you recommend this board but it doesn't seem to be the default selection in menuconfig
