Hi Stefan, hi everyone,
unfortunately I'm still struggling with the USB driver (and therefore Network) of the Raspberry Pi 2 (and 3).
As one can see, for the RPi 3 sometimes! the USB driver works and therefore I assume the same should be possible for the RPi 2. At least they they do share the same USB/Network-Chip (LAN9514).
I checked the memory map and adapted the base addresses accordingly, the interrupts seem to have not changed between RPi 1 and RPi 2 (apart from the multicore aspect).
Even some USB urbs are sent until the error -92 appears.
I currently have no idea where else to look and therefore I would be helpful for any hints I can get, regarding how I should continue to solve the problem I have with the USB driver.
Is the usb_otg/usb_dwc driver just not compatible with the Raspberry Pi 2 and I should look at the current driver situation in the Linux Kernel? As far as I know usb_otg/usb_dwc was used in the early time for the Raspberry Pi 2 until it got replaced by dwc2? Anyone has an idea if/what big difference there is between the driver versions dwc and dwc2? Would it make sense to look at the new driver and port it to Genode?
I saw that some changes were made regarding the USB support in Genode with version 18.08 - does this change anything for the RPi?
Thanks in advance! Any help is appreciated!
Regards, Alexander
