For STM32F429ZIT6 not work with MOSI SPI3 on pin PD6

?

On the other pins PC12 and PB5 MOSI signal works.

Well based on the alternate function table, it should work. If using a custom board, make sure the soldering is good and there is no electrical conflict on the PCB trace. Othewise, check if there is an errata sheet related to this topic.

Try one MOSI at a time, not all of them at once.
