Hi,

Is there any connector on the AM243x-EVM to test Sigma Delta PRU output ?

Thanks,

Eli

Eli,

Are you asking about the pr<k>_pru<n>_pru_r30_out[1] signal mentioned in table 6-365 of the AM243 TRM, or something else?

Note that all of the PRG0 signals are available on the High Speed Expansion Connector of the TMDS243EVM. The easiest way to access these pins is using the TMDS243DC01EVM breakout board for the High Speed Expansion Connector.

Thanks,
Mike

Hi Mike,

I would like to test sigma delta code I have.

I'm not sure which and where are the output pins on the 243x-EVM , I can connect to.

Thanks,

Eli

Eli,

Are you using sysconfig to set up your pinmuxing? You should be able to select with sigma delta pins from sysconfig, then you can use the breakout board mentioned above to access the pins.

Thanks,
Mike
