With ESP32S2, SD card read works in main loop, but will crash when called in a subroutine. #4716

RudyFiero · 2021-01-14T05:42:38Z

Hardware:

Board: ESP32-S2-Saola-1M
Core Installation version: ?1.0.0? ?1.0.1-rc4? ?1.0.1? ?1.0.1-git? ?1.0.2? ?1.0.3?
IDE name: Arduino IDE 1,8.13
Flash Frequency: 80Mhz
PSRAM enabled: no
Upload Speed: 115200
Computer OS: Windows 10

Description:

I can read a file on a SD card if I try and read it from Setup() or in Loop(). But if I have the same routine in a subroutine I get a crash.

Sorry if I have not done a good enough job with the formatting. I always have difficulty with it, but I can't put the time in to fix it. I should have been in bed a couple of hours ago.

that }8.13 in the subroutine I would guess is a typo? Can you decode the backtrace please?

RudyFiero · 2021-01-14T12:17:38Z

Yeah. I was trying to enter the Arduino version and I was starting up a new session with the IDE and it changed the focus. Something like that.

I have not done much with ESP32s yet. I don't know how to do a backtrace yet, I have not installed and decoder. I'm assuming it is like the ESP8266, if so then I should have no problem. I can't look at this until tonight. Right now I need to get this working in loop(). I was hoping to demo something to my managers today.

RudyFiero · 2021-01-14T13:44:06Z

In my application I tried moving the file read routine into loop() and have a flag to trigger it. It doesn't work. So maybe it working in loop() with the above code isn't triggering the problem.

This is from the code above.

In my application (the above post) I have it do (inline) the file read in setup() without a crash. But in loop() it causes the crash in the above post.

RudyFiero · 2021-01-15T00:48:46Z

I think I used an older ESP32S2 code to generate the above stack traces. I will do it again but with a version that is more recent.

I had had something similar.
Move the „SPIClass SDSPI(HSPI);“ to the top of the sketch.

See:
https://github.com/venice1200/MiSTer_tty2oled/blob/main/MiSTer_SSD1322_SD/MiSTer_SSD1322_SD.ino

Maybe it helps.

Could someone help me to fix this error AllanOricil/esp32-mfa-authenticator#9
I cant read/write/append files anywhere in the loop. It only works inside the setup. I have no idea why this happens.
