Problem with PSRAM in the tutotial/convert_tool_example with esp32-S3-DevKitC-1 (AIV-655) #140

Closed msalexms closed 9 months ago

msalexms commented 9 months ago

The program compile and build ok, but in the monitor I get this error:

E (260) quad_psram: PSRAM ID read error: 0x00ffffff, PSRAM chip not found or not supported, or wrong PSRAM line mode
E (263) cpu_start: Failed to init external RAM!

I am using the last version available of ESP-DL and ESP-IDF.

I use the official guide

The problem was the mode of the SPRAM. I have to change it from QSPI (Quad Mode PSRAM) to PSRAM was OPI (Octal Mode PSRAM) in the menuconfig.

This might help you also. https://github.com/espressif/esp-idf/issues/6288#issuecomment-1468725900
