With ESP32S2, SD card read works in main loop, but will crash when called in a subroutine. #4716
Description
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.
Sketch: (leave the backquotes for code formatting)
//Change the code below by your sketch
/*
Connect the SD card to the following pins:
SD Card | ESP32
D2 -
D3 SS
CMD MOSI
VSS GND
VDD 3.3V
CLK SCK
VSS GND
D0 MISO
D1 -
