[ERROR] usb3380_context_init_ex Unable to open USB3380

[ducnguyenAstro]

When running ./test_libusb3380 -t -l2
with XTRX attached on the USB3 box and USB3 port is connected.
lsusb did see the chip as:
Bus 002 Device 002: ID 0525:3380 Netchip Technology, Inc

and dmesg command:
dmesg | grep usb

test_libusb3380 is a basic test utility to check whether USB3380 wrapper is working. It's not doing any XTRX related things.
Probably you meant ./test_xtrx -t -l2 ?

[smallkid]

hi i have issue when testing the libusb3880
when running sudo ./test_libusb3380
[ERROR] usb3380_int_csr_cfg_read Unable to usb3380_int_csrin_sync!
this error also show on log when running osmo-trx
kindly advice

[sergforce]

Can you run ./test_xtrx -t -l9 to see what's happening?

[smallkid]

i tried this is the output
sudo ./test_xtrx -t -l9
Segmentation fault (core dumped)
btw i use ubuntu 16,04LTS i686 and port is USB 2.0

[smallkid]

this is the output when i run osmo-trx-xtx
sudo ./build/Transceiver52M/osmo-trx-xtrx -C osmo-trx.cfg

Unfortunately, I wasn't able to repeat Segmentation fault.

Can you run under debugger so I can get insight where it fails

gdb --args ./test_xtrx -t -l9
