AURIX™ Forum Discussions

Hello all!

I am currently experimenting with FreeRTOS and the TC275 lite kit. The starting point for my experiments is the FreeRTOS port from the Aurix_AudioAppKit (https://github.com/Infineon/Aurix_AudioAppKit), which is already quite an exciting piece of software, especially since it uses the GTM to generate I2S signals.

 The FreeRTOS software compiles for the TC275 under the AURIX Development Studio and flashing a LED and simple task handling works. However, I have a strange problem.

 When I start the software on the TriCore using the AURIX Development Studio, it always takes about 5 seconds before the system starts and the LED starts flashing. Therefore, I have added the UartTask from the Aurix_AudioAppKit, which regularly outputs information via vTaskGetRunTimeStats(). Enclosed are the two different outputs and the used software.

Start via AURIX Development Studio

 Task statistics 19 - UART RX Count: 0

UART task 54744 <1%

IDLE 4785042 68%

LED task 496 <1%

UART TX task 1033 <1%

Tmr Svc 2111544 30%

UART RX task 1 <1%

Starting after reset

Task-Statistics 18 - Uart RX Count: 0

UART task 52013 2%

IDLE 2539971 97%

LED task 471 <1%

UART TX task 993 <1%

UART RX task 1 <1%

Tmr Svc 143 <1%

So, the cause seems to be in the “Tmr Svc”. However, I have not created this. Can someone help me here?

Hi all,

I am new for AURIX MCUs. Could you please help me with 3ph PWM generation, when over/undersampling condition could be requested on-line?

I assume I should use the GTM module, 3 (A)TOM channels to generate the switches control signals with the desired switching frequency and one additional (A)TOM channel to generate the PWM waveform with the desired sampling frequency to synchronise sampling/control ISR with it, but how can I synchronise my "switching" and "sampling" counters?  

Thank you!

hello

Recently, We have tested the transfer speed of EMMC without DMA.

But we have tested the read and write speed,

Read speed is about 37MByte/s

Write speed is about 21MByte/s

However, the bandwidth of the reference manual is 400Mbits/s(about 50MByte/s)

Hello,

Is someone can share source using illd to trigger Adc group conversion with atom.

My Adc conversion is never launched 😞 

thanks in avance
