Dear all,
I could able to program the .bof file on snap program using the old casperfpga
package.
I am able to see the register values at using the listdev. Where I am trying to
write and read those registers I am getting errors.
is that KATCP version issues ?
fpga.listdev()
Out[2]:
['adc16_controller',
'adc16_use_synth',
'adc16_wb_ram0',
