Reading suggestions to start programming with STM32H747 like mcu, especially with GCC

I'm starting my studies on programming for Single Chip MCU with multicore, and I'm having a little trouble finding material on this topic.

I read a post here in the community about the NXP's LPC4300 which is a Cortex-M4 + M0, which was very instructive, but I am focusing my studies on the STM32H747, a Cortex-M7 + M4 dualcore, since it is used in the Arduino line which is base of my work.

Could you please indicate readings, books, appnotes that will lead me to success in compiling code for this chip and the like, especially using GCC, or only with the native ST compiler?

thanks.
