I

remodeled

DemonstrationProgram

of

ST32Cube

into

STM32F746G-Discovery

and

was able to

play

the

MP3

in

audioplayer

.

My

MP3Program

may

sometimes

do

Stall

in

Error

.

Will

there be

the

good

method

to perform of

Debug

in

FreeRTOS

?

Best Regards.

Output diagnostic and telemetry information about flow and status via the VCP attached USART, or via the SWV debugger channel, and viewable with the ST-LINK Utilities.

Running the code in a debugger might also provide some fine grain understanding, but first you probably want to get a feel for the mechanics of what the code is doing, and how tasks are interacting.

Thank you for

a

reply

I

intend

to use

,

but

do not

understand

how to use

.

Should

I

output

it

simply

in

printf

?

In something like Keil you'd have to provide fputc() type functionality using ITM_SendChar() to get information via SWV. The SWO (PB3) pin needs to be connected to the debugger, and the viewer needs to be configured to the frequency of the core.

I

use

System

Workbench

for

STM32

.

Debugger

is

GDB

and

OpenOCD

.

I

appoint

SWD

in

Interface

in

ST-LinkV2

in

Device

of

Script

.

__STATIC_INLINE

uint32_t

ITM_SendChar

(

uint32_t

ch

)

I

check

Function

mentioned above

.

Yours sincerely,
