Hi,

The TFT (Application) Kits include the TLF35584 Safety Micro Power Supply. A feature of the TLF is that there is a watchdog which should be serviced by software running on the AURIX via the SPI connection. The demo code supplied with the kit included this code, but your code does not. There are three ways to solve this problem.
You can add the code to your project to service (or disable) the watchdog feature of the TLF35584
If you are using a debugger, you can add a script that runs when the debugger resets the AURIX and disables the watchdog.
You can modify the hardware to disable the watchdog by pulling the TM pin of the TLF35584 high. There are pull up and pull down resistors on this pin in the hardware, by default the pull down is fitted, this can be removed and a pull up resistor added.

Hello,

I wanted to know if there are any differences for double pulse testing compared to IGBT's?

Thanks!

If I use TOM to generate PWM, then will interrupt clear by CPU or GTM have it's own co-processor to clear it.

Hey tomonori,

There's a thread over here that might help: https://www.infineonforums.com/threa...ll=1#post15266

I've been looking for additional commands and ways to use the software from the command line without much success.

Dears,
another question from my side:
What is the maximum dv/dt for an SiC MOSFET turn-on and turn-off? How is it affected by current and temperature?
Thanks for you help

4 pin have an aux. Source connection could help to improve the switching efficiency ,the turn on loss is around 60%~70% , tun off loss is around 80% when compare with 3pin.
It is also good for the parallel usage.The separate Kevin Pin sperate itself with the E pin which conducting the high current ,without the attenuation of the gate voltage coming from the power emitter, the switching of the IGBT becomes faster than in the standard TO-247 package.

Hello,

I am working on TC264 Project using Eclipse + Rt-druid v3 and TASKING Compiler.
As known, we can only flash th eexecutable .hex file to AURIX TriCore board.

Could you help me please generate the hex file in order to flash the program?

Thank you.

Best regards,

The short-circuit time should derating with the bus voltage, gate voltage and temperature increase ,

Yes, this is possible. You need only have attention on write access to safety endinit protected registers (e.g. Pxx_PDR) to avoid a parallel access from 2 CPUs to the endinit of the safety watchdog.

I think the problem is this line:
uint32* reserved_data_pointer = (uint32*)reserved_data[i];
here you set the pointer reserved_data_pointer to the content of reserved_data[i] and then the reserved_data_pointer is set to an invalid address and the next line traps.
I am not sure what you will do but change the line to:
uint32* reserved_data_pointer = (uint32*)&reserved_data[i];
Maybe this solve the problem.

Hi,

The DAVE_Init function is defined as weak function that you can override.

Hi,

Only BUTTON2 pin (P1.15) is an input to one of the ERUs. For BUTTON1 (P1.14) you need to poll the state of the pin in SW.

Hi,

You could go using the XMCLib (check the examples provided in the XMCLib for using these functions)

XMC_I2C_CH_Init();
// Configure input pins
// Configure interrupts / events
XMC_I2C_CH_Start();
// Configure output pins
XMC_I2C_CH_Stop();

XMC_UART_CH_Init();
// Configure input pins
// Configure interrupts / events
XMC_UART_CH_Start();
// Configure output pins
XMC_UART_CH_Stop();

Jesus

You could implement message passing or shared memory using IPC methods or semaphores.
