TMS320C6657: How to disable system_printf in NDK?

Shine

Part Number: TMS320C6657

Hello Champs,

Customer used NDK+AD capture interrupt. He found that the system_printf would influence the AD Interrupt. So he wanted to disable the system_printf in NDK.

He disabled it as follows.

But the console still print the TCP information.

Is there other configuration missed?

Thanks

Hi Shine,

We need to make changes to the XDC Script (It is the ".cfg" file in the project).

This document explains the XDC Scripting https://www.ti.com/lit/ug/spruex4/spruex4.pdf

For this purpose, please refer to Section 4.3.7

You can set SysMin's bufSize to zero.

var SysMin = xdc.useModule('xdc.runtime.SysMin');
SysMin.bufSize = 0;

No characters will be written to the internal buffer then. Note: you'll still have some overhead for the System_printf call. If this is too much impact, you can look at using the Log module instead (e.g. Log_print instead of System_printf). You have finer granularity with control over this module.

Thanks,
