CW305 no attribute INITB_STATE / is_programmed

Sass · May 9, 2024, 12:38pm

Hi all,

I can neither call INITB_state() nor is_programmed() on a cw305 instance anymore.
help() on CW305 instance shows in fact, that these methods vanished.
I was seeing warning-like exceptions are being generated, would handing these be the way to go from now on? i.e. can we rely on those warnings being generated?

Best regards,
Marvin Saß

Maybe you moved to the master branch? It’s still there on the develop branch; it just hasn’t made its way to master yet:

              # calculate checksum
              vccsetting[2] = vccsetting[0] ^ vccsetting[1] ^ CW305_USB.VCCINT_XORKEY
          
              self._naeusb.sendCtrl(CW305_USB.REQ_VCCINT, 0, vccsetting)
          
              resp = self._naeusb.readCtrl(CW305_USB.REQ_VCCINT, dlen=3)
              if resp[0] != 2:
                  raise IOError("VCC-INT Write Error, response = %d" % resp[0])
          
          def is_programmed(self):
              """Is FPGA programmed

Perfect, thanks a lot!
Was setting up a new system based on main branch.
