Re: DFU Process got stuck in XU224 board
One of possible cause is related to the reboot problem in XU224, is it required to update anything in reboot routine for XU224 ?

Re: Different Channel Count with different sampling frequency
Thanks for your reply. But I think it is different case. We need to change the channel count dynamically, it is not allowed to reboot the unit. Thanks anyway !

When we select higher sampling frequ...
