ErrDisp error when exit homebrew app and open another app.

[sn76496]

I am working on porting rockbox (SDL2 app) to the N3DS.

The app seems to be working fine, but when I exit using the home menu and open any other app I get the ErrDisp error screen:

An error occurred (ErrDisp)

Error type:         generic

Porcess ID:         15
Process name:       menu
Process title ID:   0004003000008f02

Address:            0X0022951c
Error code:         0xc8a0cc04

Press any button to reboot.

I am using:

Luma v13.3.2
New Nintendo 3DS, latest firmware.

Can you please tell me a possible cause of that kind of error?

Error code indicates this is an APT issue, you should look there. Ensure you are using the latest versions of tools (devkitARM, libctru and so on)
