AURIX™ Forum Discussions

Hello everyone.
I would like to use the AURIX TC3 in external input clock mode. Referring to the TC3 manual, in section 10.3.1.1 it says to connect the clock source to the XTAL1 pin and leave the XTAL2 pin in high impedance.

In my case, hower, this microcontroller is mounted in the triboard TC3x9, and referring to the Triboard manual, the diagram on page 45 shows the connection of the 20MHz crystal in the two pins XTAL1 and XTAL2.

In my case, i would like to use an external clock with a frequency of 12MHz, and this clock is obtained by means of a square wave signal generator with duty cycle = 50%. The problem is that from the moment i connect the external clock signal to the XTAL1 pin of the board, i don't get the right behavior of the micro.

At this point i would like to ask the following questions:

1)Does the fact that the 20MHz crystal is connected to the XTAL1 and XTAL2 pins via the board allow an external clock signal to be used?

2)Are there any requirements for the external clock signal? I found from the data sheet that the input frequency must be between 10MHz and 40MHz, while i found nothing about the signal amplitude.

Is it possible to drive Aurix GPIOs simultenously?
for example if I have one byte of data and I would like to send this data to 8  GPIO pins simultaneously 
and the same for reading,  can I read the ports simultaneously? and concatenate the values in one byte?

can BSPLIT/BMERGE help is this issue?

Hi, guys

l was using TC334. l was working for bootloader. And l want now how to jump to 0x800080000. Its my __start address of Application.

l attempt to use __asm("ja(0x800080000)"), but studio can identify ja. It tells me a spelled incorrect of ja. And l also use following code. l used it in ARM core and it can work, but failed in Tc334. So what's the correct jump code in TC334?

l used ads(v1.9.0) with iLLD driver.

UINT32 appEntry = 0;
static void (*pJumpToApp)(void);
IfxCpu_disableInterrupts();
appEntry = *(UINT32*)(BOOTLOADER_CFG_APP_START_ADDR);
pJumpToApp = (void (*)(void))appEntry;
pJumpToApp()

Hello,

for my application I would need to reconfigure the sample frequency of the AURIX EDSADC during runtime.
Is there a way to achieve this with the EDSADC?

Thanks and regards!

Hi,

When I am generating  the code using pin mapper in Tricore IDE v6.3r1, generated code seems to be different from previous version(same .pincfg file). Is that expected?

Thanks

Hi,

I have updated the tasking linker file that we had received with the startup code. However, whenever I first time flash the board with elf generated from that linker, I get below error message:

@User13836 could you please look into it? Am I missing/misplacing something in the linker? If I reset the micro and run it again, the code is able to run all the cores.
