• RE: LSF0108: LSF0108 signals cutting off

  

  Clemens Ladisch

  The CC's output pin must sink the current through all pull-up resistors. With higher pull-up currents, a higher V OL is expected. (The CC3301 datasheet specifies 0.45 V for 4 mA, i.e., 112.5 Ω in the worst case.) As long as it is below the other device…

  TXV0108. Consider redesigning your system to use 1.8 V I/Os on the FPGA.

  Thanks, I reduce the pull-up resistors from 10k to 470ohm. Now SWD works. Although I still did not find the root cause, I will keep new circuit in our Launchpad design.
