osmo-remsim-client-st2: asserts when the simtrace2 is in dfu-mode
Added by lynxis over 2 years ago.
Updated over 1 year ago.
Description
When the simtrace is in dfu mode, the osmo-remsim-client-st2 asserts:
osmo-remsim-client-st2 -V 1d50 -P 4001 -C1 -I0 -S0 -H 1-1.4 -A3 -i <SOMEIP> -p 9998 -c 1 -n 0
DRSPRO INFO ../rspro_client_fsm.c:308 RSPRO_CLIENT(server){REESTABLISH}: Creating TCP connection to server at <SOMEIP>:9998
Assert failed rc == 0 user_simtrace2.c:309
This platform has no backtrace function
Aborted

this is quite odd as I would expect osmo_libusb_get_ep_addrs() to fail already at an earlier stage? Isn't DFU only implemented with control pipe requests? So there should be no buil/irq descriptors and hence osmo_libusb_get_ep_addrs should fail?
I can confirm the problem still exists:
