Hello everyone,
I am using the embedded python block in GRC to realize
some simple functions. All works fine in the GRC local
set-up. However, if I connect a USRP sink to the flowgraph
which includes that python block, and set the sample rate
more than 20 MHz (I need 100 MHz in my case), it will keep
output "UUUUUUUU....", and then GRC will stop working.
I tried the defaulted python block, where the output is
simply multiplied by a factor k, the same overrun problem
happened. And GRC works fine with the USRP sink if the
python block is not used.
Does anyone know what could be the problem?
Thank you!
Regards,
Wei
