BBB - Read high speed ADC via GPIO pins

BEAGLEBK: ADC read on PRU

FARZIN ALM
Prodigy 30 points

Part Number: BEAGLEBK

Hi,

I am trying to read an external high speed ADC from TI (part number: ADS5410,  max sampling frequency: 80MSPS ) using Beaglebone black and transfer it to 512 MB on board DDR-RAM using EDMA controller . I was wondering if it is possible to do this task using PRU subsystem and if there is any upper frequency limit for PRU reading external high speed ADCs.

Thank you for your help.
