Description
Board
WT-ETH01
Device Description
This is a regular esp32 with an ethernet-port bolted on.
Hardware Configuration
There's an SD-Card reader attached to pins
#define pin_SD_MISO 12
#define pin_SD_MOSI 13
#define pin_SD_SCLK 14
#define pin_SD_CS 15
Version
v3.0.6
IDE Name
PlatformIO
Operating System
Ubuntu Linux 24.10
Flash frequency
default
PSRAM enabled
no
Upload speed
115200
Description
The problem occurs with an iSCSI target running on the ESP32. During setup (DHCP, iSCSI logon) all is good.
Yet when regular i/o occurs (e.g. reads and writes to the device), an interrupt watchdog happens.
Sketch
Sofar I haven't been able to make a smaller sketch showing the behaviour.
The same 'sketch' runs fine on teensy and on linux (yes).
Debug Message
Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0).
