FTM usage of imx7solo

[269244908]

Hi,everyone

  I want to use the imx7solo to control BLDC without sensors. And I have read the reference manual of imx7solo.  About the FTM, I have some question:

1. Which onchip module will receive the output trigger of the FTM? I can't find any information about this. 

2. Which signals are the hardware synchronization source? The RM has referred to TRIG0/1/2, I cannot see any information about these trigger source.

3. Can I use the FTM of imx7solo to control BLDC without sensors? The imx7solo has no PDB module. How can I synchronzie the ADC and FTM?

Hi daqin

I am afraid such ftm imx7solo examples are not available, sorry. Since ftm module

is the same may be useful to look at below documents:

https://www.nxp.com/docs/en/application-note/AN5303.pdf 

https://www.nxp.com/docs/en/supporting-information/Flex-Timer.pdf 

Need sample code of FTM for PWM Generation 

linux/pwm-fsl-ftm.c at master · torvalds/linux · GitHub 

Best regards
