The host lib (usrp_prims.cc) maps usrp_read_fpga_reg into usrp_spi_read. I have found and fixed the problem. The problem is due to a compiler bug in SDCC 2.4.0. I've rewritten spi.c (read_byte_msb) to work around the bug. Give it an hour for sourceforge to sync the developer CVS to public CVS, then update and rebuild usrp.
