I inserted code.
OUT 0x04 endpoint works, but 0x84 IN endpoint doesn't.
I use libusb from Linux PC to communicate with nrf52840 via USB. At PC I call function "libusb_bulk_transfer" - it results in timeout - and at SOC no enter to event handler.
I see USB registers - IN endpoint packet counter don't increment, and no response.UGate.23.03.2020.zipUNrf.23.03.2020.zip
Hi,
Thanks for providing both firmware and host software to test with. Makes it very easy to look into.
Firmware built with SDK v16.0.0 (SES)
I built the software on ubuntu 19.10, and ran it:

Seems to be working? Could it be that I'm missing something?
Kind regards,

I got something different

complete.

Segmentation fault
I insert you cycle with send_ep() as you advised - got above mentioned message
Hi,
Here's the edited project I'm using:
I also included the .hex file I've used in the build folder.
Could you see if this works?
Kind regards,
Håkon
