Hello jleb! There's no problem fetching the samples from the ADC subsystem and store them in the external memory block (or DRam area). You don't need both PRUSS, one can do that.
But the ADC subsystem isn't fast enough. It needs 14 cycles to perform a step and a further cycle to start the step sequence. In your case that's 1 + 4 * 14 = 57 cycles at 2.4 MHz, which results in a maximum sampling rate of 42.2 kHz. Depending on the signal impedance, you may need some open delay to stabilize the input. In order to test the ADC subsystem, you may have a look at libpruio <http://beagleboard.org/project/libpruio/>. It can be used to configure ADC steps and fetch samples in a ring buffer.
