ESP32-USB-Soft-Host and EEPROM.h and preferences.h

[martelnov]

Hello,
I have a problem. It looks like there is a problem working ESP32-USB-Soft-Host with eeprom.h and preferences.h
A crash occurs when trying to write to flash.

Guru Meditation Error: Core 1 panic'ed (Cache disabled but cached memory region accessed).

hi,

Cache disabled but cached memory region accessed

please specify the espressif core version used with your sketch, there's a chance it's too old and needs to be updated to an earlier version.

Arduino-ESP32 v 2.0.11

[tobozo]

see this post where an untested solution is suggested, using this code in your setup, before USH.init():

USH.setISRAllocFlag(0)

if it doesn't solve the issue, then I'll need much more information e.g. esp32 type, library version, operating system,a code example that reproduces this error, and any other detail you may find relevant.

Compilation error: 'class USB_SOFT_HOST' has no member named 'setISRAllocFlag'

BINGO! I downloaded version 1.0.4 and it runs fine. Thank you very much.
