qSPI (no MTRS2 output)

[#1]

Hello,
im want to send data over qSPI (4 data lines) at 10Mbaud with a word and Frame length of 16 Bit. I can see the CLK, MTSR0, MTSR1 and MTSR3 as outputs on the oscilloscope but i cant get any output on the MTSR2 no matter which pin i choose.

My program looks sth. like this:

uint16_t myData; //global variable

//cyclic called interrupt routine
void timerInterrupt(){
myData++;
EnableStartOfFrame (SPI001_Handle0 );
SPI001_WriteData(&SPI001_Handle0,&myData,SPI001_QUADMODE_HPC_OUTPUTMODE);
EnableEndOfFrame (SPI001_Handle0 );
}

Anyone an idea why i cant get any change on MTSR2? On the oscilloscope the output is always low.

Best Regards
Werner

Maybe the configuration of the GPIOs is not complet. Can you post your configuration of this pins?

This is my SPI configuration:

Hi Werner,

I think moost probably is the pin did not set properly by the DAVE.
I try to reproduce on my side and I found out that my MTSR1 pin is not configured.
Therefore, for your workaround now, please manually configured the pin (either Pn_HWSEL or Pn_IOCR register).
We will logged this issue in our system to fix it in future.
Thank you.

Thanks for your help it was the HWSEL register.
If anybody else has this problem i just added:

PORT3->HWSEL |= 0x10000000;

after the DAVE_Init();

this will enable the hardware control path for Pin 3.14.
