Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

C++20 for bare-metal microcontroller programming
Being able to mark a register RW vs RO vs WO and have the compiler check your access is great. Have you also considered the case where a register bit is cleared by writing a 1 to it (or to another register)? I've also implemented my own approach for a general register class (bits and pieces stolen from various other projects): https://github.com/4ms/mdrivlib/blob/main/drivers/register_access.hh I use types for registers, rather than structs, which lets me do RegisterSetClear to handle the case where different registers set and clear a bit.

Anyone using the STM32MP1 ? (Dual ARM cores (A7 + M4), Linux, Ethernet, CAN, USB, DACs, ADCs...) FreeRTOS on the 2nd core ?
2x A7 cores for running an OS (Linux, Android) or you can run bare metal code on them too. (https://github.com/4ms/stm32mp1-baremetal)

Hard Real Time Embedded Linux in MPU(cortex A7+M4) Question
As others have said, it’s not real-time Linux because it’s not Linux. I also want to add that if you require hard-real time and are ok with not having Linux, you can also use the A7 core for hard-real time applications. Some example projects here: stm32mp1-baremetal

STM32MP1 SAI Module Slave RX FIFO not filling. TX works fine
I didn’t go through the 29 bytes you’re sending to the codec, but I do see you call the array “master”. The codec should be setup as slave. It could cause problems if the codec and ARM chip are both trying to be the master (generating the clocks). You’ve double/triple checked those bytes set up the codec properly? You may want to spell them out like I’ve done here: https://github.com/4ms/stm32mp1-baremetal/blob/master/examples/audio_processor/lib/mdrivlib/drivers/codec_CS42L51_registers.h

Real-time Audio Processing Question
And if you want more processing power and memory, there are some audio examples in this project using a Cortex A7 (STM32MP157) bare-metal (512MB RAM, 800MHz) https://github.com/4ms/stm32mp1-baremetal
