MCU-PLUS-SDK-AM263X: Variable realtime streaming a via DAP for debug

Nicolas B.

Hi,

I was wondering whether it would be possible, via the Debug Access Port of Sitara AM263x and code composer studio, to stream at "high speed" (> 1 kHz) a variable (in OCRAM) to scope it ?

Thank you for your support.

Hello Nicolas,

To clarify, are you wanting to have something external to the SoC that is changed when the variable is changed? For example, if variable = 1 then GPIO = high - and then use an oscilloscope on the GPIO to see the behavior?

Regards,

Erik

Hi Erik,

thank you for your answer. In fact, my main use case is the opposite, I would like to see on my PC some analogic signals I have in global variables (e.g. see the output of a given digital filter). One of the motivations to do that is to validate the processing chain of an analog signals from ADC input line to processed signal.
