Hi !

I'm working on Tricore Tc397 SPI.

It appears like datawith is 2-32bits.

Is there a way to send over SPI in one frame with more than 32bits for example 64bits?

One frame here i mean is CS stays low and SCLK is continuous.

Hi infineon

As the title said, I got a problem with "Vddk", I use the next formula to configure "Vddk", but some products(not all, same program) will exceed the threshold(±2%) when ambient temperature increasing, and the calculated value close to low boundary? Could you give me some advise? Thanks

i'm trying SPI_CPU_1_KIT_TC334_LK.. I've joined SPI_A to SPI_B (confirmed on schematic for dev kit - - i hope).

when the code runs i dont have an LED on which says the data has transfered ok -- 😞 .. sad face .

i've run it a few times and set a break point . plus used a logic analyser ..

 

 

if i disconnect the MISO / MOSI lines i receive no data .. so i know the SPI slave is getting data..  .. 

i've added this line , but nothing has changed ..

I am using TC387. When I download *.elf file using Trace32, it works OK. But I download *.hex file using Trace32, it does not work. Even if I download *.elf file using Trace32, if I disconnect Trace32 and power off and on, it does not work. I have several boards but most of them have no problem. But some of them (around 10%) have this problem. What should I need to check? Show Less

Hello!

I have the following code that is not working. After first call of readRegister response is 0, after calling readRegister the second time, I receive the expected value. 
Can you please help? I must mention that my application is based on the Infineon SPI_CPU_TC334 training and I've also tried to change  spiMasterChannelConfig.channelBasedCs but I still don't receive the expected behavior.

I've also attached the source code for QSPI.
Thank you!

Hi,

after flashing (iROM) the LCDDemo provided by the Free Aurix Entry Toolchain, the TC2X7 V1.0 Application Kit Board is performing an reset within an second after every startup of the application. Therefore i can't flash the board by the Toolchain anymore, because no connection can be estabiled or the board is disconnected after the board resets.

Is there any possiblity to halt the board after the startup and stop the execution of the the application code e.g. by an hardware pin, so that i can erase the application code or flash a new one?

I'm thankful for every hint, which could lead to an solution of my problem!

Best regards
Lukas Show Less
