Hi

Is it possible to increase alter the testptp program or something under it to allow a longer pulse from pps out pin on the cm4 ?

-w 4095 is the maximum which works ....from what I can see the testptp supports larger values ...however this is the maximum value allowed with this hardware without error ....is there anyway to increase this please ?

maybe there is good reason this cannot be done ?

Thanks
