WROVER-B PSRAM fails to initialize on newer versions of arduino-esp32 #9041

Open marchingband opened 11 months ago

marchingband commented 11 months ago

Board

ESP32 WROVER-B

Device Description

ESP32 WROVER-B on a custom PCB (based on this open-source design https://www.sparkfun.com/products/21307)

Hardware Configuration

DAC, eMMC, opto isolator

Version

v2.0.14

IDE Name

Arduino

Operating System

macos

Flash frequency

40

PSRAM enabled

yes

Upload speed

115200

Description

I have an application which I have been using for many years without issue, however I received a board from a user who made his own with what looks like an older version of the ESP32 WROVER-B, and the PSRAM fails. If I upload the application from my older laptop, which is running 2-year old versions of the Arduino-esp32, the program works as expected. With the newer versions, it fails. Using newer version of ESP32 WROVER-B, the new library works fine, it is just this one (seemingly older) chip on which is fails.

I don't know if this will be helpful, but here is a photo of the part in question.

Jason2866 commented 11 months ago

A quick look in the project you linked shows that many IDF calls and functions are used. core 2.0.14 is based on IDF 4.4.6. There are changes in IDF which you have to port. PSRAM in general works with core 2.0.14

marchingband commented 11 months ago

@Jason2866 sorry maybe I was not clear enough. This project works well on most WROVER-B chips, using any version including 2.0.14. There is only a tiny subset of chips, like the one in the photo, for which the project fails to initialize PSRAM, and this failure only occurs on 2.x.x, but not 1.x.x.

I know this sounds very strange. I have spent many hours debugging this. I use this code base everyday, so I can be sure that what I am reporting is accurate and complete to the best of my knowledge.

Jason2866 commented 11 months ago

Do you have added the psram fixes? Probably a ESP32 rev.0 or 1 which does need

marchingband commented 11 months ago

@Jason2866 no, how do I do this in Arduino IDE? thanks!

Jason2866 commented 11 months ago

Sorry, never used ArduinoIDE. Doing everything with Platformio

marchingband commented 11 months ago

@Jason2866 I also use PIO a lot, and I have tried the same thing with PIO and this line:

build_flags = 
    -DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue
    -DCORE_DEBUG_LEVEL=3

But it does not fix the issue.

marchingband commented 11 months ago

This is the exact part that fails: https://www.lcsc.com/product-detail/WiFi-Modules_Espressif-Systems-ESP32-WROVER-B-16MB_C529591.html

Jason2866 commented 11 months ago

Really weird. Curious if Tasmota will crash too, when trying to init PSRAM. For testing could you flash the Tasmota32 Webcam Build? (not having a cam device is not a problem) this build includes PSRAM use and the fix. Install is easy. Just via the WebInstaller from https://tasmota.github.io/install/

@marchingband No it does work. If not connected within 3 minutes it restarts. Search for AP tasmota-2A7FCC-8140 and connect to. Open address 192.168.4.1 It errors out when trying to start the espcam (as expected) and continuous starting.

From the log so far it detects PSRAM and has it enabled. More infos when the device is connected to your WLAN and you can browse to Tasmota Information page.

The 16MB flash are detected and used too. Not needed flash space is used for File system (12600kB)

marchingband commented 11 months ago

@Jason2866 So then what is the fix for Arduino or for PIO?

lbernstone commented 11 months ago

Are you using the psram pins (16&17)?

marchingband commented 11 months ago

@lbernstone I am not. As I said the application and board works perfectly with most WROVER-B chips.

do you mean GPIO 16 and 17? They are not even available on WROVER-B, PIN 16 and 17 are GPIO 13 and 9, which I do use, but I do not believe these are connected to PSRAM?

Jason2866 commented 11 months ago

@Jason2866 So then what is the fix for Arduino or for PIO?

@marchingband Nothing. Just the application code is different.

But we use a forked own framework. Maybe the changes and settings we did in IDF and Arduino is the reason? You can try with Platformio:

platform  = https://github.com/tasmota/platform-espressif32/releases/download/2023.12.00/platform-espressif32.zip

SPIFFS support has been removed.

marchingband commented 11 months ago

@lbernstone @Jason2866 Using PIO, with platform = https://github.com/tasmota/platform-espressif32/releases/download/2023.12.00/platform-espressif32.zip the problem is gone. This should be enough information for the Arduino team to fix the bug, do you agree?

marchingband commented 11 months ago

playing around with PIO versions here is my results:

WITH PIO and build_flags = -mfix-esp32-psram-cache-issue: platform = espressif32@6.2.0 -> PSRAM fails platform = espressif32 -> PSRAM works

WITH ARDUINO IDE using board "esp32 by espressif": version 2.0.2 -> PSRAM works version 2.0.14 -> PSRAM fails version 3.0.0-alpha3 -> PSRAM fails (E (84) quad_psram: PSRAM ID read error: 0x7aa9ae06, PSRAM chip not found or not supported)

Jason2866 commented 11 months ago

@marchingband Just using that is a very very bad idea platform = espressif32 It tells Platformio it can use any version found. Always! pin the version. Latest core 2.0.14 can be used with Platformio with platform = espressif32 @ 6.5.0 So your Platformio test does not tell what version used.

And no it is not easy to say what makes the difference when using the Tasmota framework. Maaany settings are different in IDF sdkconfig. Some changes in IDF and Arduino are done too.

Maybe it is in esp32-hal-psram.c

E (257) psram: PSRAM ID read error: 0x7aa9ae06
[    14][W][esp32-hal-psram.c:71] psramInit(): PSRAM init failed!

We have a small change in this IDF file against the original.

marchingband commented 11 months ago

@Jason2866 I came here to report a bug, is there anything else I need to do? Are you able to triage it?

marchingband commented 11 months ago

I did some regression testing here are my results, using PIO

platform = espressif32@4.2.0   ; esp-arduino 2.0.2 ; ESP_IDF 4.4-beta1 -> PSRAM WORKS
platform = espressif32@4.3.0   ; esp-arduino 2.0.3 ; ESP-IDF 4.4.1     -> PSRAM WORKS
platform = espressif32@5.1.0   ; esp-arduino 2.0.4 ; ESP-IDF 4.4.1     -> PSRAM FAILS
platform = espressif32@5.2.0   ; esp-arduino 2.0.5 ; ESP-IDF 4.4.2     -> PSRAM FAILS

marchingband commented 11 months ago

@mrfaptastic @maho24at I doubt very much it is related to my bug report. On S3 you must set the PSRAM type very carefully or it will fail DIO/QIO etc must be set right for the module or it will fail to init.

maho24at commented 11 months ago

in my case, I can upload normal sketches, like the Blink sketch, and it will execute normally, if I upload a program that uses the PSRAM intensely (which BTW runs on other ESP32 perfect fine) my N8R2 as well the N32R8 start to boot loop..

so you think that is another issue?

TD-er commented 11 months ago

For ESP32-S3 this is indeed a completely different issue as the S3 is very strict on what SPI settings you use for both flash and PSRAM. I tried to make an overview here on what SPI settings you need (!!!) for the S3 or else it will bootloop. See: https://espeasy.readthedocs.io/en/latest/ESPEasy/ESPchips.html#quad-octal-spi-mode

About this issue, I think it has to do with the "silicon bug" in earlier revisions of the ESP32-WROVER. Detection of PSRAM was not working well and the Tasmota platform packages does indeed have a fix for this included.

You are correct. I have deleted my comment. The issue I experienced was due to accidentally using GPIO38 which is allocated to the Octal-PSRAM. Once I did not use that GPIO (and any of the others) the issue went away.

TD-er commented 10 months ago

@mrfaptastic Thanks for that link, now that I see it I remember that's where I got that table info from. So I will add it as a source to my table.

Jason2866 commented 10 months ago

https://api.riot-os.org/group__cpu__esp32__esp32s3.html for the s3 a very complete and correct comprehension. On the other side infos for the c3 are very wrong. But S3 issues are completely off topic in this thread. and not related to this very specific esp32 PSRAM issue.

@me-no-dev i compile with visual micro; but it's also the same problem with PlatformIO;

I use this config : [env:esp32] platform = espressif32@6.7.0 board = esp32dev framework = arduino

me-no-dev commented 5 months ago

How about with Arduino IDE (1 or 2)

Mbouk commented 5 months ago

@me-no-dev is the same! Capturearduino

me-no-dev commented 5 months ago

Can you get a close up image of the module, so that we can read what's on it? All modules we have here work fine on 3.0.1, so you must have one from a batch with different PSRAM. @igrr any clues? Regression in IDF's supported PSRAM chips?

Mbouk commented 5 months ago

ESP32

Jason2866 commented 5 months ago

@Mbouk I would be interested if it does fail with my fork build too. Can you test with Platformio using this platform?

platform = https://github.com/tasmota/platform-espressif32/releases/download/2024.06.10/platform-espressif32.zip

The debug sketch is removed in my build. Just try with your sample sketch. @me-no-dev If my fork works i have an idea where to search.

Mbouk commented 5 months ago

@Jason2866 it does not work, Did I configure correctly? CaptureESP

Jason2866 commented 5 months ago

@Mbouk Yes, config looks correct. Did it install stuff? If yes the setup is working. In this case my theory what it could be is wrong. No idea what causes the issue.

me-no-dev commented 5 months ago

We will try to find the same module and give it a shot. It might take a few weeks though (depending if we have it in the EU office or not). @P-R-O-C-H-Y please check in the office when you are back next week.
