I decoded guru meditation errors

Hi.

i decoded guru meditaion error and i see this errors :

PC: 0x40112665: jsvInitJsVars at src/jsvar.c line 316
EXCVADDR: 0x0000000c

you can help me for fix error?

I when have insert javascript codes on esp-wroom-32 show this errors.

just wondering, is this something else than the topic you already created here https://forum.espruino.com/conversations­/383867/ ? why to have two?

as for the decoded stack trace - that's great you have it - so you can check what is failing at line
`jsvInitJsVars at src/jsvar.c line 316 - possibly some null pointer or read from invalid address?

maybe, just guessing from E (567) psram: PSRAM ID read error: 0xffffffff, you are accessing address that should be in external SPI RAM which is not working/is not present on your board?

This conversation is related to the previous conversation.

When I make my own new firmware for esp32, after I flash it and enter the espruino editor, unfortunately, when I try to save the javascript code on it, this error is displayed. After a thorough search, I was able to decipher this error. The loop is src/jsvar.c and this error is not complete and accurate.

this file (jsvar.c) :
https://github.com/espruino/Espruino/blo­b/f173832d935f87033f560b88de4af4f3a0fa1c­de/src/jsvar.c#L316

I use the esp32-wroom module, the firmware that Mr. Gordon put in espruino runs without errors, but when I built it myself, I encountered these errors.

This conversation is related to the previous conversation.

it is better to not create new conversation for same issue as someone may later answer to the other one => mess and duplicated/wasted effort

I use the esp32-wroom module

see previous post #3 - just a guess - wroom module does not have extra PSRAM at all (?) , maybe you are building for wrong ESP32 board variant? PSRAM is optional

!!! I wanted to clearly state the decoded error in the new conversation.

I did exactly what was said for the ESP32

https://github.com/espruino/EspruinoTool­s

I went through all the steps

make clean && BOARD=ESP32 make

I entered it and it was created, then I flashed the boot files.

But unfortunately, these errors occurred.

Can you output the new build for esp32?

If you've done this, please help others fix this problem by making a tutorial video and uploading it to YouTube.

You will be doing a great favor.

Even if you tell me how to do the PSRAM settings, it would be great

Check discussion here https://github.com/espressif/esp-idf/iss­ues/8306 about wroom vs PSRAM.

when searching now in espruino code, PSRAM is enabled here https://github.com/espruino/Espruino/blo­b/6df01b93404975befd5ff12a02e2625fe2f888­08/targets/esp32/Changes_V3.1/sdkconfig#­L180 since year 2018

however that flag about ignoring missing PSAM is set to yes https://github.com/espruino/Espruino/blo­b/6df01b93404975befd5ff12a02e2625fe2f888­08/targets/esp32/Changes_V3.1/sdkconfig#­L184 so it should boot

sorry I don't use espruino with esp32 very much and I am not sure I have wroom32 module to check this error, will check

also I am not familiar with state of PSRAM support in espruino, here is some comment that is a bit cryptic https://github.com/espruino/Espruino/blo­b/6df01b93404975befd5ff12a02e2625fe2f888­08/boards/ESP32.py#L28
maybe your variables are too large so it tries to use missing PSRAM, so reducing the size of variables may help? but I am just guessing really, someone more familiar with ESP32 should better comment

you can also try to modify sdkconfig and disable PSRAM there, then it may work or fail with out of memory => too many variables

Tnx for this links i later test.

These items were also useless, however, thank you

Can you send me the address of the sdkconfig file, I'm not sure which one it is

maybe @MaBe could help, I don't understand ESP32 target very much. I'd try to modify file app/build/include/sdkconfig.h by maybe it won't work as it looks already pregenerated in some state.

As for variable size I was wrong, look like for ESP32 target the number of variables in board file is mostly ignored and just works as a baseline to determine size in bytes of each variable. So it only defines maximum number of variables, real value is determined at startup based on available free memory.

Hmm, please send the board file you used to build your own firmware.

Hi.

ESP-wroom-32

Firmware zip : http://microcosm.app/out/ANkHi

I build this firmware with EspruinoBuildTools>ESP32 uploaded on github.

have you changed any thing in this file?

https://github.com/espruino/Espruino/blo­b/master/boards/ESP32.py

Nope

Which xtensa gcc version are you using?

I did not check this

But I went through all the steps mentioned in github with wsl Ubuntu and then I got the output

Is it possible to record the training video and upload it to YouTube?

When does this guru error occurs?

when i turn on esp32

make erase_flash
make flash
and try again

Could you make a video tutorial of all the things you described and upload it to YouTube? I think I didn't do part of the work or maybe I should add something but I don't know how to make a video tutorial and upload it. If you do this, I am sure that those who have this problem like me will be solved and then this issue will be closed once and for all.
