Hi,After a lot of testing/debugging (previously in thread “Firmware /
bitstream for USRP2 Rev 4”) by using a re-compiled version of txrx.bin
the gnuradio firmware source code, I was able to find out where the
Regardless of whether the usrp2 is connected to a machine or not, it
stuck in the following loop in ethernet_mac_miim_write(). We verified
the firmware goes through the following sequence of code:
- main() (in txrx.c) calls ethernet_init() (in ethernet.c)
- ethernet_init() calls eth_mac_miim_write(PHY_INT_CLEAR, ~0) (in
- eth_mac_miim_write() gets stuck in :
while((eth_mac -> miistatus & MII_BUSY) !=0)
Apparently, the hardware status is always seen as busy.
Any ideas on what might be wrong?
