Hello,
I just start using a NUCLEO-H743ZI2 board with a modification to use quartz X3 of 25Mhz (that seems to working correctly) and now I am trying to configure SPI3 interface in polling mode but SPI is working only when using PER_CK as input :
When I am using PLL1Q input clock with different speed from 240 to 60 Mhz there is no SPI frame transmit on the output of the microcontroller. When I use the PER_CK input everything work correctly. Is any one having the explaination of this behaviour ?
Thank you very much if you take time to read until this line =)
Regards
