PSRAM initialization failed error (IDFGH-4170) #6031

Open Sanketa54 opened 4 years ago

Environment

Environment Module or chip used: ESP32D2WD IDF version: v4.3-dev-1561-g357a27760322 Build System: idf.py and vscode idf extention Compiler version: xtensa-esp32-elf-gcc (crosstool-NG esp-2020r3) 8.4.0 Operating System: WIndows 10 Power Supply: USB PSRAM = External ( 64 MB)

Problem Description

I have been configured external psram with ESP32 D2WD chip tried on idf platform with esp-idf extention on vs code. I flashed the example of https://github.com/espressif/espidf/tree/master/examples/system/himem but not getting the expected output.

Expected Behavior

I (254) spiram: SPI RAM mode: flash 40m sram 40m I (259) spiram: PSRAM initialized, cache is in low/high (2-core) mode.

Actual Behavior

10:52:02.435 -> [0;32mI (203) psram: This chip is ESP32-D2WD[0m 10:52:02.435 -> [0;31mE (209) cpu_start: Failed to init external RAM![0m

PLease help me with the solution or suggest me easy example just to check the psram

What hardware are you using? How is the PSRAM connected? What GPIO pins do you have in use?

Sanketa54 commented 4 years ago

@Spritetm : PSRAM : APS6404L-SQR-ZR (64Mb) PSRAM is connected externally to ESP32D2WD chip revision1 with GPIO pins CLK - GPIO6 and CS- GPIO10

Spritetm commented 4 years ago

CLK for GPIO6 is non-standard, I think - by default it should be GPIO9, unless you modified this in Menuconfig.

Sanketa54 commented 4 years ago

I tried modifying that in menuconfig but it didn't worked for me. It was showing the same message "cpu_start: Failed to init external RAM!"
