Question
STM32H750 CubeIde MPU setting ignored
Hello, I am trying to get Ethernet working, I don't like HAL, switched all is possible to LL library. @Piranha Hi, if this is a bug please add to your report if someone try use LL configuring Ethernet.
Platform Linux
CUBEIDE Version: 1.7.0
STM32Cube_FW_H7_V1.9.0
After a lot of odd hard fault I focused again on MPU configuration and I discovered LL CUBEIDE MPU TEX setting got ignored. Is this a bug or am I wrong in some way?

}Must be IMHO

void MPU_Config(void)
{
/* Disables the MPU */
LL_MPU_Disable();
/** Initializes and configures the Region and the memory to be protected

LL_MPU_ConfigRegion(LL_MPU_REGION_NUMBER0, 0x0, 0x030040000, LL_MPU_TEX_LEVEL1|LL_MPU_REGION_SIZE_16KB|LL_MPU_REGION_FULL_ACCESS|LL_MPU_INSTRUCTION_ACCESS_ENABLE|LL_MPU_ACCESS_NOT_SHAREABLE|LL_MPU_ACCESS_NOT_CACHEABLE|LL_MPU_ACCESS_NOT_BUFFERABLE);

}Thank anyone try address this issue.
