I had to declar my section to NOLOAD in the linkerfile which had the same
effect as .noinit.
And in the c-programm I had to work with the __attribute__ command.
C-Programm:
volatile uint32_t shared_mem_array[1024]
__arttribute__((section“.my_pru_sec“)))
Linkerfile:
SECTIONS{
…
.my_pru_sec(NOLOAD) > PRU_SHAREDMEM,PAGE2
...
}
This link helped me with this problem:

Thanks for your help
