Can't compile "fatal error: hal/cpu_hal.h: No such file or directory"

[Fredkopp]

Feeling kinda dumb, but I'm getting this error trying to compile the usb_test.ino. There is no such file in this library, but the "usb_host.c" is referencing it. What am I missing? This is the exact error message: "/home/user/Arduino/libraries/ESP32-USB-Soft-Host-main/src/usb_host.c:18:25: fatal error: hal/cpu_hal.h: No such file or directory compilation terminated."

hey thanks for your feedback :+1:

looks like you're using an older version of arduino core for esp32, the requirement for this driver is arduino-esp32 2.0.0 and should be available in your boards manager.

[Fredkopp]

Hey that did the trick! Thank you very much!

[tobozo]

closing this as solved, have fun !

In arduino board manager the latest version is not available for installation,still the latest available for updatation is ESP32 1.0.6, Also tried downloading from github still also doesnt work. C

[tobozo]

1.0.6 is quite olde, you probably need to update the package url in the additional boards manager (arduino preferences)

you can remove the old URL and use this one instead:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

the highest version of this package is currently 2.0.5

Yeah its done Sir :) Thankyou so much. Can I ask you a doubt, In my circuit ,ESP32 is flashed via usb through CH340 ,is that possible to make a HID without removing the CH340 as my device is a 2/3 inch thermal printer there is the need of a COM port as well as a HID.

[tobozo]

this library uses regular pins from the ESP32, so you can do whatever you want with the unassigned pins

[Vineeth-B007]

Okay sir, Mine has Zero pins available. Thinking to remove CH340 and use HID ONLY
